Observation Reports
All times shown are Eastern Standard Time (with
adjustment for Daylight Savings Time during appropriate months) in
24-hour clock format. In parenthesis is how long it took to perform
the observation. Sketches are first drawn at the eyepiece/binoculars,
then (in later observations, at least) resketched inside at a desk to
make it look a bit better. Then, the colors are inverted. In some
cases, other GIMP processing may be done (e.g. to fix the color of a
star or brighten stars and/or darken the background).

| Schwassmann-Wachmann 3 Frg. B |
| Constellation: | Lyra |
| Instrument: | 9x63 Meade Travelview Binoculars 5.8° field of view |
| Power: | 9x |
| Description: About as bright as M13, nucleus seen as well as fanned tail. Only 3-4 stars of Corona Borealis visible with unaided eye, and saw stars near Vega down to about magnitude 8 in binoculars. The comet was easily found in the same field of view as Vega by looking for the prominent (in binoculars) triangle of stars, HIP92098 (mag. 6.03), HIP91674 (mag. 6.62) and the binocular double Epsilon Lyrae (mag. 4.65 and 4.56). The comet was just outside the triangle, just below (ESE) the midpoint of the base defined by HIP92098 and Epsilon Lyrae. At 22:53, a faint (mag. 7 or so) satellite crossed the field of view, entering at 1o'clock and exiting at 8o'clock, passing just south of HIP91674. At 22:57 a brighter satellite (mag. 5 or so) crossed the field of view, entering at 9o'clock and exiting at 4o'clock. (lines aren't drawn that accurately. I did not specifically witness it passing through or close to any stars other than the one mentioned.) Neither was listed on www.heavens-above.com, but Starry Night's latest update listed the brighter as Cosmos 1833 rocket booster, mag. 2.16. Haze went in and out of the field of view, making the comet seem to brighten and fade. |

| Constellation: | Cygnus |
| Instrument: | 9x63 Meade Travelview Binoculars 5.8° field of view |
| Power: | 9x |
| Description: Milky way, though not visible to unaided eye, was just visible in binoculars. In binoculars, stars visible to almost mag. 9. With unaided eye, stars visible to about 4.5 in area of Deneb and Vega (nearly-full moonglow washed out area of Albireo at the other end of Cygnus). Comet was brighter than before (mag. 6.3 according to Starry Night). It could be found by aiming binoculars at the right (upper) end of the crossbar of Cygnus (Delta Cygni, mag. 2.84) and moving to the right one binocular field and down a bit less than a binocular field. A chain of 5 bright stars (and one dim double, at center of image) made the field easy to spot, as did the two bright stars to the left, the three bright stars in a triangular pattern down and right, and the mini “cluster” of dimmer stars up and left. It was brightest at the nucleus, and faded as one went out from the tail. Due to fatigue, I did not fill in the field with all the dimmer stars, but there were many. |

| Constellation: | Hercules |
| Instrument: | 9x63 Meade Travelview Binoculars 5.8° field of view |
| Power: | 9x |
| Description: Moon was waxing crescent roughly westward. Fainter than main/C fragments. Roughly curved triangular nebulosity, fatter at the head and fanning out less—closer to teardrop than main/C was. Found by pointing binoculars toward Pi, Rho, and 69 Herculis, then moving rightward a binocular field to include the triangle of binocular-bright stars HIP84949 (mag. 5.53), HIP85888 (mag. 5.71), and HIP85688 (mag. 6.4). The comet was just below the centroid of the triangle. There was haze in that part of the sky so it faded and came back a few times while I was drawing it. I quit as field-of-view stars became harder to see. |

| Instrument: | 9x63 Meade Travelview Binoculars 5.8° field of view |
| Power: | 9x |
| Description: Could not tell if it was a tail and bright nucleus or a comet and a star (HIP90781, mag. 7.34). Moon was waxing crescent roughly westward. Beautiful faint gossamer nebulosity, roughly triangular. Easily found by pointing binoculars toward Vega, putting Vega and Zeta Lyrae in the field, and moving a binocular field rightward along the perpendicular bisector of Vega—Zeta Lyrae, and then down a little to center the comet. The two bright (in binoculars) stars HIP91119 (mag. 6.09, with a “tail” of three fainter stars) and HIP91235 (mag. 5.4) made it easy. |

| Constellation: | Vulpecula |
| Instrument: | Celestron C6-R 150mm f/8 refractor with 9x50 5.8° field of view finder |
| Power: | 30x |
Description: Most of the coathanger fit in the field of view, but I chopped off one star. The central star was brilliant white. Two stars of the curved hook were orange, and one was bluish-green, and one dimmer one was bluish white. The star in the line nearest the central star was bluish white, as was the one northeast of it. The remaining stars were white. Some glow (from the moon) was on the southeast portion of the field of view. I used this asterism to measure the field of view of my 40mm eyepiece.
This is easily found in the finder by pointing the telescope 1/3 of the way from Altair to Vega.
Once thought to be an open cluster, the coathanger is merely a chance alignment of unrelated stars. |

| Description: Could see stars down to Lambda (mag. 4.40) in Serpens Caput with the naked eye. 7 main stars of Cygnus visible, but I could not see Vulpecula or Sagitta. Found by aiming binoculars at Altair, then moving toward Vega, passing Sagitta, and stopping at the prominent coathanger shape. Not a true cluster, but a chance alignment of stars. The bright stars are 1 (top, mag. 4.75) and 9 (bottom, mag. 5.0) Vulpeculae. |

| Power: | 9x |
Description: Beautiful site—milky way, though not visible to unaided eye, was just visible in binoculars; made me think of the title of a science fiction story I read years ago:
“The Stars, Like Dust.” In binoculars, stars visible to almost mag. 9. With unaided eye, stars visible to about 4.5 in area of Deneb (nearly-full moonglow washed out area of Albireo at the other end of Cygnus). |

| Power: | 200x |
Description: Epsilon Lyrae is a double star in binoculars, but with higher magnification in a telescope, each component splits into a double, for a total for four stars. TYC3122-1635-1 is the Mag. 10.4 fifth star in the field.
To my eyes, three of the Epsilon Lyrae stars appeared greenish, the fourth orange. The fifth star was gray-white. |

| Instrument: | Celestron C6-R 150mm f/8 refractor with 9x50 5.8° field of view finder |
| Power: | 60x |
Description: Slightly oblate disk, two dark bands visible, three moons visible to the west. Disk was bright yellow, and bands were dark red. Moons were mere white points. As an experiment, I timed Jupiter's passing across the field of view. 0 time is when the edge of Jupiter was first visible. At 5 seconds Jupiter was fully visible. At 15 seconds, the first moon was visible. At 24 seconds, the second moon was visible. At 36 seconds, the third moon was visible. At 215 seconds, Jupiter disappeared. Thus, Jupiter transited 0.87 degrees in 210 seconds, or about 241 seconds per degree, very close to the expected 4 minutes. (Some inaccuracies from Jupiter not being exactly on the celestial equator and not passing exactly through the center of the FOV—the former increases the time, the latter decreases the time).
This shows that Jupiter has an apparent diameter of about 1.25 minutes, and the moons are distance 2.5 minutes, 4.75 minutes, and 7.75 minutes from Jupiter. For a crosscheck, Starry Night gives values of 0.75 minutes for Jupiter's diameter, and 1.5 minutes, 5.3 minutes, and 8 minutes showing some inaccuracies (partly from moons not being exactly parallel to celestial equator, partly timing inaccuracies too). The moons, from inside out, are Europa, Ganymede, and Callisto. Io is behind Jupiter. |

| Object: | M10 |
|
| Constellation: | Ophiuchus |
| Instrument: | 9x63 Meade Travelview Binoculars 5.8° field of view |
| Power: | 9x |
| Description: Could see stars down to Lambda (mag. 4.40) in Serpens Caput with the naked eye. Starfield was fairly sparse (especially as compared to the nearby Serpens Caput's head). I centered the field of view on three close dim stars in a right-triangle shape. I found the field of view by pointing the binoculars at the naked-eye star Han (Mag. 2.53) and moving to the left two fields to find two bright binocular stars (at the bottom of the drawing below) 23 and 30 Ophiuchi (mag. 5.21 and 4.81). M10 was found above 30, a little to the right, to from a 5-12-13 right triangle with 23 and 30. Globular was diffuse and dim, no visible nucleus. The two bright stars at the very top are close to M12 (not drawn, just outside field of view) which looks about the same as M10 in binoculars. At 22:57, a meteor passed through the field of view (drawn). It took about one second, much faster than an airplane or low-earth-orbit satellite. It brightened twice (both times to magnitude around 4, from magnitude about 6) as it passed through. There was no visible trail. It was white. After I finished drawing the field of view, I scanned somewhat randomly with binoculars and caught another meteor in nearby Corona Borealis at 23:08, moving roughly the same direction, passing through the field of view in less than a second, and brightening once, leaving a faint and very short lived trail one degree behind it. These might be Epsilon Aquilids. |

| Constellation: | Cassiopeia |
| Instrument: | 9x63 Meade Travelview Binoculars 5.8° field of view |
| Power: | 9x |
Description: Haze came in and out—at times, magnitude 3.43 star η Cassiopeiae was visible, but never for more than an instant. The star in the center Ruchbah (δ) was brilliant white but had the faint bluish tint associated with fluorescent lamps. The star χ appeared orangish. All other stars were white or light gray.
The moon was almost full, but behind me.
M103 is an open cluster ENE of Ruchbah, but only three stars with apparent nebulosity could be seen. The nebulosity made it look like a hazy hyphen from NNW to SSE.
I took this opportunity to check (again) my binocular field of view (advertised at 305 feet per thousand yards, which translates to 5.8 degrees). I could not put η and Caph (β) in the field of view together, but I could almost do so. The angular distance between eta and Caph is 5.3786 degrees. Thus, the true field of view of my binoculars is 5.3 degrees. |

| Constellation: | Ophiuchus |
| Instrument: | 9x63 Meade Travelview Binoculars 5.8° field of view |
| Power: | 9x |
| Description: M12 is a faint hazy patch with detectable nucleus found by aiming binoculars at the field containing Yed Posterior and the diamond belt-buckle asterism containing Upsilon Ophiuchi. Then move to the left, perpendicular to the line from Yed to the belt, two binocular fields to find a pair of stars, HIP 82405 (mag. 6.31) and HIP 82527 (mag. 6.93). M12 is just above this pair of stars. A magnitude four or so meteor (line with arrow) went through the field of view eastward at 23:07. |

| Constellation: | Hercules |
| Instrument: | 9x63 Meade Travelview Binoculars 5.8° field of view |
| Power: | 9x |
Description: M13 appears to be a hazy patch in Hercules, 1 sky arc minute in diameter. Moon has not risen, so that made it easier to spot. By defocussing the binoculars a little, I made other stars in the field the same size as M13, and picked one of similar brightness (circled). The star I picked turned out to be HIP81911 of magnitude 6.0. To check my estimate, M13's "official" magnitude is 7.0 (all magnitudes and other info from Starry Night Pro 5.8.2). It is easy to find again and again--find Hercules, find the "keystone" of Hercules. The top (roughtly NW) two stars are on each side of M13. M13 is collinear with them, about 1/3 of the way from the left one to the right one. Then, in binoculars, I find a triangle about the size of a full moon, maybe a little smaller. Two stars are HIP81848 (mag. 6.84) and HIP81673 (mag. 7.28)--M13 is at the obtuse (about 100 degrees) angle; it is almost isosceles. They disappeared when I defocussed, so I took them to be less bright than M13.
M13 appeared to be a white fuzzy patch with a noticeably bright center. None of its stars could be resolved. |

| Description: Sky was somewhat hazy, but it was mostly clear and a new moon. The field surrounding Sadr is one of the nicer binocular fields, it being in the Milky Way. Nebulosity could be seen in places, though the area immediately surrounding Sadr itself was deep black, perhaps because of contrast with bright Sadr. The overall impression was a circle within a circle within a circle—the field of view is a circle, as is some of the brighter stars surrounding Sadr, as is the apparent black area surrounding Sadr. Open cluster M29 is in the field near the left edge at about 10 O'clock. |

Description: The night was exceptionally clear for the Baltimore-Washington metro area—Delphinus and Sagitta were visible to the naked eye, as was one star of Vulpecula. The Sadr-centered field of view in binoculars had a very large, hard to count number of stars visible. The North America nebula could be (just) picked out in binoculars.
It was a faint gray-white nebulosity, with an hourglass shape just detectable parallel to the 10 o'clock to 4 o'clock line. It could be found by aiming one-fifth of the way from Gamma Sagittae to Sadr. |

| Power: | 9x |
Description: A few scattered clouds, could see but not split Epsilon Lyrae with the naked eye. Sadr (Gamma Cygni, the crosspiece star of the Northern Cross), the brightest star to the north, is slightly yellow and was very spikey in the field of view. Milky way nebulosity could be seen through the binoculars in this area—the haze drawn is where it seemed most prominent (it seemed to form a ring around Sadr, but this likely was because Sadr's glare made it invisible in its vicinity). It seemed to fork, moving southwest of Sadr, with a fork going west, and a fork going south. The west fork split again past the center of the field of view. It actually looked like numerous fuzzy globs—perhaps it would have been better to draw it that way, using some sketching analog to painting with crumpled tissue.
In the center is an asterism (marked in the sketch) that looks like a very tiny dipper—the bright star in the bowl is 34 Cygni. Just east of it is M29, which looked to me like a faint pair of stars with faint nebulosity. In reality, M29 is an open cluster—the faintest stars could not be resolved in binoculars, so they appeared as nebulosity. It has two seperated groupings of bright stars—these are probably what appeared to be two stars. Just east of M29 is an optical double. This and the dipper could help one find M29 in a telescope.
I quit before I drew all the stars, as the angle I was looking seemed to put me in an uncomfortable position and I was getting restless. I did draw a lot of the stars surrounding Sadr, as can be seen. |

| Instrument: | 9x63 Meade Travelview Binoculars 5.8° field of view |
| Power: | 9x |
| Description: M3 appears to be a hazy patch halfway between Arcturus and Cor Coroli, about one sky arc minute in diameter. Moon has not risen, so that made it easier to spot. By defocussing the binoculars a little, I made other stars in the field the same size as M3, and picked one of similar brightness (circled). The star I picked turned out to be HIP66725 of magnitude 6.21. To check my estimate, M3's "official" magnitude is 7.0 (all magnitudes and other info from Starry Night Pro 5.8.2). In binoculars, I find it easily as one star on a nearly-isoceles triangle a little longer but narrower than a full moon. The two stars are HIP66725 (mag. 6.21) and HIP67028 (mag. 7.09). M3 appeared to be a white fuzzy patch with a noticeably bright center. None of its stars could be resolved. The dimmest star seen in the field is HIP66498, magnitude 8.56 (diamond). Arcturus got a halo around it about 22:10EDT, and stars in the field became harder to see. The mist disappated some in a few minutes. Transparency went from about 4 to about 3 and back to nearly 4. |

| Constellation: | Andromeda |
| Instrument: | 15x70 Celestron SkyMaster Binoculars 4.4° field of view |
| Power: | 15x |
Description: Bright nucleus that looked like a globular cluster but elliptical in the NNE-SSW direction, medium bright elliptical haze surrounding it tilted a little counterclockwise from the nucleus, and with averted vision, very faint vertically-thin “mustache” haze trailing off. Total length, including averted vision portion, almost a degree. Everything was white or light gray except one yellow star (ν Andromedae). Tree branches obscured the area south and southeast of the galaxy. M110 and M32 were not detected. I also tried but failed to detect M31 with the naked eye.
To find it, first I found Schedar (α Cassiopeiae) which forms a “V” with γ and Caph (β). The vertex of the V points the way—I pass a prominent grouping of stars, and continue past three stars in an obtuse triangle until I find three stars almost in the line I am traveling (ο, HIP3478, and π). This line points the way exactly (the “V” only being approximate). I continue, cross a line of stars perpendicular to the three I just visited, and on the other side of that line (same distance as the three stars) is M31. |

| Instrument: | 9x63 Meade Travelview Binoculars 5.8° field of view |
| Power: | 9x |
| Description: M5 appears to be a hazy patch (fainter than M3 or M13, brighther than M10 and M12) found by locating Yed Posterior and Yed Prior in Ophiuchus, moving upward (west) to the first two naked-eye stars in Serpens Caput collinear with the Yed (alpha and epsilon), and moving to the right, perpendicular to that line, about 2 binocular fields. In binoculars, it forms a three-star chain with 5 Serpentis (Mag. 5.03) and 6 Serpentis (Mag. 5.34). Moon has not risen, so that made it easier to spot. By defocussing the binoculars a little, I made other stars in the field the same size as M5, and picked one of similar brightness (circled, HIP74895), magnitude 6.5. To check my estimate, M3's "official" magnitude is 7.0 (all magnitudes and other info from Starry Night Pro 5.8.2—I'm starting to wonder of Starry Night always puts 7.0 for Messier globulars). M5 appeared to be a bluish-white fuzzy patch with a noticeably bright center, but the blue could have been contrast with yellowish 5 and 6 Serpentis. None of its stars could be resolved. The dimmest star seen in the field is HIP75271, magnitude 8.37 (diamond). With averted vision, I thought I saw (two or three times) something hazy (question mark). It turns out to be a star HIP75014, Mag. 7.25. |

| Instrument: | 9x63 Meade Travelview Binoculars 5.8° field of view |
| Power: | 9x |
| Description: Sky was clear and dark at the zenith near M51 and Ursa Major. Alcor, the optical “companion” to Mizar, the middle star of the handle of the big dipper, was just visible to the naked eye with averted vision. Some fifth-magnitude stars could be seen. M51 was a patch of haze, just visible. With averted vision, a brighter nucleus was detectable. It appeared elliptical, but the companion galaxy was not resolved separately. It is easy to find in binoculars: first, aim at the end star of the big dipper (Alkaid). Move the binoculars in the general direction of Cor Coroli (or Denebola on the lion's tail) about one field. An asterism I think of as the “tropical punch” is visible, complete with tiny umbrella to shield the drink from the “sun” of Alkaid. 24 Canes Venaticorum forms one top edge of the glass nearest the umbrella. Then, M51 is at the bottom of the glass, forming roughly a 5-12-13 right triangle with the two stars making the bottom (HIP 66004 and HIP 65768). |

| Description: M57 looked like a gray-white magnitude 8.5 star in binoculars. No detail was detectable. It would not be recognized as a Messier object except for being in the right place and having the right magnitude. Surrounding starfield was pretty, being at the edge of the Milky Way (not visible to naked eye in Bowie, but nebulosity just visible in binoculars. It is found by aiming the binoculars at roughly the midpoint between Beta and Gamma Lyrae, and looking for a triangle of gray-white 8.5 magnitude stars (requiring averted vision) right on the line from Beta to Gamma. Two stars are north of the line, and the third “star” is M57, south of the line. |

| Instrument: | Celestron C6-R 150mm f/8 refractor with 9x50 5.8° field of view finder |
| Power: | 80x |
| Description: Fuzzy white donut with prominent hole in center of field. All stars seemed white or gray. To find, aim scope at Vega first. In the finder, Vega is very bright and a pair of stars, one a double, are nearby. Move toward the one not a double. A third prominent star can then be seen. The nondouble and the third form one side of a parallelogram of bright stars. Move away from Vega perpendicular to that line to find the opposite side with two bright stars, and a dimmer one ¼ the way across the line. The ring nebula is right at the midpoint of the line. Center the finder there and, if the finder is aligned well, the ring nebula is in the field of a low-power (30x, 40mm plössl in my case) eyepiece. It appears as a fuzzy ring, the hole possibly not evident. Center it before using higher power. At 200x (6mm plössl) it was too dim to work with, though it nearly filled the field of view. |

| Description: Both M81 and M82 were very faint, hard to detect visually. M82 was fainter than M81. M81 was close enough to another star I at first mistook it for a double star with the nebulosity sometimes seen on double stars. It appeared to be a faint elliptical smudge with a star-like nuclei. In the sketch, the view is centered on HIP48803. At 22:15, a satellite passed through the field of view (shown). To find this field in binoculars, aim at the top of the bear's nose (23 UMa, mag. 3.62) and move outward (North) along a line perpendicular to the line formed from the other two stars of the bear's nose (Upsilon, mag. 3.75, and Omicron, mag. 3.34). Pass a quadralateral of stars (a bright triangle means you are too far west), and arrive at a pentagon that looks vaguely like a smiley face. Continue on the line to find a boomerang shape with west end at 24 UMa, mag. 4.53, and the galaxies are to the east. (CF M82) |

M92 was a dim white fuzzy patch with a brighter white star-like nucleus. By defocussing, its magnitude seemed about the same as the circled star, HIP83593, mag. 6.43. Starry Night, however, claims M92 has magnitude 7.5. It can be found by looking at the left (northern) edge of the Hercules keystone (e and p Herculis). Let that be the base of an almost-equilateral triangle with the vertex moved p-ward slightly. That vertex is M92. In addition, p and i Herculis (dragon-ward hand) form a nearly-isosceles right triangle with M92 at the vertex (M92 is slightly closer to i than p). |

Description: I could just barely see HIP60582 (Mag 8.09) yet did not detect HIP 60976(Mag. 7.84) so magnitude limit in binoculars was between 7.5 and 8, say 7.75. I used Starry Night Pro version 5.8 to find names of stars in field. I estimated seeing/transparency from this view.
A satellite passed through below center of the field. Magnitude was around 4 or 5. No match on www.heavens-above.com.
The moon was full, to approximately SSE, causing the sky to glow on this side of the field.
The optical double 17 Comae Berenices (Mag. 5.28) and HIP60891 (Mag. 6.62) has seperation 2'25”. It is not a true double—they are 12.84 light years apart. |

Description: Centered is NGC869, and below and to the left is NGC884. The former had three visible stars, and the latter 5. It is found by looking at the line formed by Ruchbah (δ Cassiopeiae) and Segin (ε Cassiopeiae). Both just fit in my field of view. I move downward (nearly East) perpendicular to that line by just over the length of that line and find a spray of stars, with what at first looked like three pairs of doubles, but on further looking, the bottom two pairs had more. It is reminiscent of Orion's sword. Perseus's head is just below the field of view. Both are open clusters.
The green line shows where a satellite passed through at 1:50 EDT. |

| Description: Shark Fin asterism near Boötes' pipe (a few degrees to the southeast of the field shown). At 23:08, a satellite not listed on Heavens Above or on Starry Night passed through the field of view moving southeast. At 23:10, a satellite passed through the field of view moving north by northwest. Starry Night claims it is CARTOSAT-1. Both were magnitude about 6 or 7. The “blue” stars are dimmer stars—this does not reflect color. All stars appeared white. |

| Constellation: | Pagasus |
| Instrument: | 15x70 Celestron SkyMaster Binoculars 4.4° field of view |
| Power: | 15x |
| Description: Very faint, low in the haze. To find it, I went to easily-visible Altair, then to Delphinus, which tonight was just detectable as a bright spot in the haze, then down to Equuleus (only visible in binoculars—easy to recognize with double star at top left, single at top right, bright at bottom right, dim at bottom left), and then used the top two stars of Equuleus as pointers to Enif (just visible with naked eye with averted vision, but off and on) which was orange in the haze (out of the sketched field, to the bottom), and then one binocular field upward (toward Albireo) to get to the Magnitude 6.09 star HIP106243. The globular cluster M15 was barely visible, and then only momentarily. It seemed slightly elongated in the north-south direction. |

| Double Cluster in Perseus |
| Constellation: | Perseus |
| Instrument: | 15x70 Celestron SkyMaster Binoculars 4.4° field of view |
| Power: | 15x |
Description: Exceptional night in Bowie—milky way was just visible in Cygnus, five stars of Delphinus visible easily, and Andromeda Galaxy could just be detected as a hazy area in the sky. Double cluster was reminiscent of the sword of orion—three prominent star groupings, two having prominent pairs surrounded by nebulosity and a few faint resolved stars, and the third three prominent and a handful of faint stars among nebulosity. It was easily found by looking for the W of Cassiopeia, then moving perpendicular to the rightmost stroke of theW away from the W (downward in this situation) a few binocular fields, and it is very hard to miss.
NGC869 is the middle and upper double, and NGC884 is the lower grouping. |

The globular cluster M2 was just above the naked-eye star Sadal Suud, in the direction of Enif. The nucleus was a disc taking up most of the area. A thin outer boundary of fuzz surrounded the nucleus. |

| Description: Exceptional night in Bowie—milky way was just visible in Cygnus, five stars of Delphinus visible easily, and Andromeda Galaxy could just be detected as a hazy area in the sky. In binoculars, the nuculeus had a definite asymmetric oval shape from NE to SW, the NE side being slightly larger. It was surrounded by eccentrically-elliptical haze rotated slightly clockwise from the major axis of the nucleus, and somewhat brighter close to the nucleus than away. This elliptical haze had very faint extensions roughly NE and SW making the total size a degree or so. M32 and M110 were not detected. |

| Description: Very faint—all that could be seen was that some parts of the eyepiece were brighter than others. The most noticeable brightness was the “neck” (“Mexico”) following a trail of stars. There was also glow to the bottom left that seemed seperate—perhaps the 10-day old moon reflecting off the inside of the dew shield. This was found directly below Deneb. |

| Instrument: | 15x70 Celestron SkyMaster Binoculars 4.4° field of view |
| Power: | 15x |
Description: Moon was like a searchlight shining on me. Trees in my yard were a problem—I found a spot in which the field of view was just visible between the tops of two different trees, and M11 disappeared behind some of the leaves while I was observing, forcing me to move my chair a foot or two. Visibility wasn't all that good—there were scattered clouds, and though this is peak time for Perseids, I saw no meteors after 30 minutes of observation.
Despite less-than-optimal conditions, M11 was bright and, once spotted, was hard to miss. I needed a clear enough night to find the tail of Aquila (I tried to find M11 another night, but not being able to see the tail with the naked eye and not being sure which binocular stars were the tail, I never found it). It was easy to make out the “V” shape of the open cluster, as well as something next to it (below it in the field of view drawing), probably HIP92507 (mag. 8.46). I drew it fuzzy thinking it was part of the cluster, and it was faint enough to look a bit nebulous. The bright stars at 10 O'Clock and 3 O'Clock are 12 Aquilae and Beta Scuti, respectively. |

| Description: Moon hadn't risen yet. Exceptional night with Milky Way just visible. To see objects in this direction, I had to be in my front yard looking over my house and the trees behind it. This had the disadvantage of streetlights and car headlights, as well as neighbors' entry lights. Still, the objects I looked at tonight were bright enough to show through. At 21:48, my next-door neigbor's motion sensor lights came on—I soon realized my own motions were triggering them. M16 shares the field of view with M17 (c.f. M17 observation). M16 is on top—rectangular with four stars resolved, one brighter than the other three. |

M24 was roughly elliptical, football-shaped, with nebulosity going through it diagonally, with some nebulosity along the bottom edge of the football too.
It is not a true cluster, but the "starcloud" is a "window" in the dust lanes of the Milky Way, giving us a direct view of the next spiral arm over, the Sagittarius Arm. A similar window to the south, the Large Sagittarius Star Cloud, is a window onto a portion of the galactic core. |

My next-door neighbor's motion sensor lights were on only a few minutes this night, happily. Sagittarius is a great place to find Messier objects, except for being in a hard-to-view section of the sky where I live. Lagoon Nebula M8 reminded me of Orion's sword. I saw two optical doubles and a single, each surrounded by bright bluish-white nebulosity. This one was particularly beautiful. The two nebulosities on the left had comet-like tails pointing toward the southwest, while the one on the right was elliptical in the east-west direction, with maybe a slight bulge toward the northwest. M20 and M21 are visible in the same field of view.

| Constellation: | Orion |
| Instrument: | 15x70 Celestron SkyMaster Binoculars 4.4° field of view |
| Power: | 15x |
| Description: Moon was waning gibbous in nearby Pisces, making the sky appear deep blue. There was haze, as evidenced by a halo around the moon. Andromeda Galaxy, near the zenith, was visible in binoculars, but was not very large. It was a cool night. The sword of Orion could barely be seen with the naked eye as a faint smudge in the sky, fading in and out with the haze, with no stars resolved. The nebulosity (M42) about the central triple (two bright stars and one very faint star to the east of the southeastern-most of the pair) was roughly bean shaped—more surrounding the upper (northwestern, really the Trapezium) star than the southeastern star (θ2), and more to the right (southwest) than to the left. The third star of the triple (TYC4774-935-1) was only visible with averted vision and was hard to separate from the glare and nebulosity. The fourth star outside the nebulosity (ν, in M43 whose nebulosity I did not detect) was much easier to see, though it faded in and out with the haze. |

| Description: Moon was waning gibbous in nearby Pisces, making the sky appear deep blue. There was haze, as evidenced by a halo around the moon. Andromeda Galaxy, near the zenith, was visible in binoculars, but was not very large. It was a cool night. Only the bright red star Aldebaran was visible to the naked eye—it is not really part of the cluster, though. Under better conditions, the Hyades appear to the naked eye as a rounded V shape with Aldebaran on one tip. The entire cluster (including one prominent star of the V) did not fit in the field of view. The naked-eye V consists of Aldebaran, the pair of yellow stars with two bright stars to the left and right, the apex at the far right of the field of view, the triangular pattern of stars including the blue-green and yellow star, and one more star not in the field of view. |

| Power: | 15x |
Description: Good night, better than most, moon wasn't up. Cool but not cold. The three stars of Triangulum were visible to the naked eye. Three of the bowl stars of the Little Dipper were also visible. Andromeda Galaxy could just be detected with the naked eye, and was brilliant in binoculars. This was a very faint haze in a lozenge-shaped asterism. The nucleus could just be detected as an ovoid, large end on top. Wisps of haze extended left and right from the nucleus. In addition, there was an even fainter elliptical halo around everything. My interpretation was an edge-on disk with halo, but in fact, it is a nearly face-on spiral.
It was difficult to detect—when I first came outside, I thought I might have detected haze in the lozenge, but was not sure. After looking at M34 and giving my eyes more time to adjust, I returned to M33 and it was clear.
The hardest part in finding M33 was in finding the faint Triangulum constellation. On a prior night, I failed even to find the constellation. However, if the constellation cannot be detected, it would be hard to detect the galaxy as well. |

It first appeared as an optical double, but further study showed the leftmost member was surrounded by nebulosity. Thus, it is roughly spherical, perhaps slightly elongated north to south, with visible nucleus. |

Pleiades was visible at first as a smudge in the sky with the naked eye low in the haze, and by the time I finished, it had risen enough that four stars could be resolved. By then, in binoculars, the chain of stars coming from Alcyone had six visible members, plus the bright stars at either end. The overall impression was a handful of bright stars in a field of dim stars, all forming a patch in the sky. This is my best observation of M45 yet. |

| Andromeda Galaxy |
| Constellation: | Andromeda |
| Instrument: | Zuhmell 20x80 supergiant astronomical binoculars 3.6° field of view |
| Power: | 20x |
Description: The Moon was just past new and setting in the west. Sky was clear and dark, with the Great Rift clear in the Milky Way, which stretched from horizon to horizon. 11 stars of Hyades were visible to the naked eye, as was Andromeda Galaxy, which was a clear oval. The double cluster looked dumbbell shaped, and the Alpha Persei Association looked like a particularly bright patch of the Milky Way.
The elliptical haze of the galaxy stretched across the entire 3.6 degree field of view. I did not detect M32 or M110 (though I had the previous night when I didn't sketch it). |

The double cluster looked dumbbell shaped, and the Alpha Persei Association looked like a particularly bright patch of the Milky Way.
M33 filled the entire diamond asterism used to find it. It showed an apparent spiral arm above the brighter elliptical nebulosity below. Unexplained nebulosity surrounded the stars above and to the right--could have been haze in the atmosphere, or even my imagination.
A satellite (Iridium 911) passed through around 18:23. |
