ORION
by Steve Coe
13" f/5.6 unless noted

NGC 1662 Pretty bright, pretty large, not rich, not compressed, cluster of 19 stars with several nice pairs at 100X. A few stars of 8 to 9 mag show in the 11X80.

NGC 1788 Pretty faint, pretty large and irregular in the 17.5" at 100X. It looks like a paint splatter with a pretty bright star at one edge. With the 6" f/6 on a 6/10 night at Sun Valley Parkway it is faint, small, round with 2 stars involved and next to a star of 10th magnitude, using the 22mm Panoptic eyepiece. Going to the 8.8 mm almost makes it disappear.

Granite Wash Mt. S+T=6 13" 150X--bright, pretty large, elongated 2X1 in PA 135, irregular figure. 10th mag star on north end, bright spot on south end is definately not stellar and about 9th magnitude. Several other pretty faint stars involved, the UHC does not help--actually makes it less contrasty.
"The Peanut Neb"

NGC 1973 Granite Wash Mt. S+T=6 13" 100X--little round nebula on the north side of 1977, I see a bridge attaching them together. It is not much, a little blob with one 9th mag and two 11th mag. stars involved.

NGC 1975 Granite Wash Mt. S=7 T=9, great night 13" 100X--double star 10-10 mag with about 10 arcsec seperation with fuzz from NGC 1977, not much of an object to get seperate NGC number.

NGC 1976 (M 42) Extremely Bright, extremely large, irregular shape, very much brighter in the middle at 100X in the 13". The Great Orion Nebula is certainly a showpiece and it probably is the most observed deep sky object in the Winter sky, it deserves that position of honor. On a night I rated 9/10 for transparency at a very dark site in the Arizona desert the center of the Sword of Orion is fuzzy to the naked eye. In my 11X80 finder the "batwings" feature of the nebula is obvious, with the western side brighter. Going to the 13" at 100X, the nebulosity is larger than the 30' field of view. All 6 six stars in the Trapezium section are seen and a background of very faint stars embedded in the nebula are at the limit of averted vision. The area around the Trapezium in very, very mottled, like storm clouds. The dark marking called the "fish mouth" appears three dimensional. The dark area is obviously in front of the nebulosity. The dark lane extends beyond the nebula to the NE. Raising the power to 220X will hold 10 of the faint stars in the nebula steady. The central region around the Trapezium has "rays" of nebulosity that extend into the darker region to the south. The Trapezium stars are contained within a "hole" in the nebula, it appears that these stars lit off and blew away the material nearby. At all powers, the nebula is a pale lime green and has pink fringes where the nebulosity is brightest. Overall a spectacular object that no photograph or drawing can truly capture.

Ultimate Star Party, McDonald Obs., Oct. 95, S=7, T=9, 25" f/5--

Orion Neb in 25" and 16mm is cosmic experience. Mottling in area around Trap has an amazing amount of contrast. There are tiny orange stars embedded within the nebula across the face of the nebula in a wide variety of locations, many near the Trap and Fishmouth. Spectacular!!

6" f/6 at Buckeye, 7/10 S+T at 40X with 22mm Panoptic there are 31 stars involved in this nebulosity, including the 4 seen in the Trapezium. All four nebulae fit in this field; M 43, M42, NGC 1980 and NGC 1973, which includes Iota Ori. A spectacular object with many subtle changes in brightness and form. Light and dark areas intertwine and the entire Loop of nebulosity is seen, up and over the bright area of the Trapezium. Adding the UHC filter makes the nebula have more contrast, but gets rid of many subtle variations and delicate star groupings, I like the un-filtered view better. Raising power with the 14mm UWA eyepiece shows off some of that delicate structure better and the dark "Fish Mouth" area near the Trapezium is more contrasty. Going to the 8.8mm UWA shows off several orange stars in the nebula and splits the Trapezium, the E and F members are glimpsed 20% of the time. All in all, a "WOW!" object, first class.

Sentinel 6" f/6 6/10 S+T 38mm Giant Erfle will just take in the entire Sword and the Orion Nebula is the central 50% of the field. There are 38 stars in the nebula. With the 8.8mm there are several very faint orange stars in the nebula and the higher power splits the Trapezium 4 main stars easily. The E and F members are just glimped 20% of the time.

Granite Wash Mt. S=7 T=9, great night 13" 100X--Great view!! A beautiful fog around the Trapezium, dark "fish mouth" enters from the East side, the bright "Proboscus" off from Trapezium toward SE. There is more nebulosity to SW of Trapezium than side with proboscus. At 220X the "breaking up of a mackeral sky" effect in the nebula is obvious. The D and F stars in the Trapezium are seen at 220X.

Vicksberg S+T=7 binoculars 8X25--nice view of all of Belt and Sword and nebulosity, all fit in wide field. The nebula is small, but the view is nice.
10X50--entire Sword fits in FOV, the wings or flame aspect of the nebula is easy.
11X80--11 stars involved in nebulosity, central region is obviously brighter than the wings. The nebula M 43 is easily seen as comet shaped. The "upper" loop toward Iota ORI is just seen.

NGC 1977 Bright, large nebulosity that has several stars involved at 100X in the 17.5". The fainter parts of the nebulosity extend to the edges of a 30' field of view.

Granite Wash Mt. S=7 T=9, great night 13" 100X--bright, large, elongated 2X1 in PA 0, nebulosity with 8 stars involved. 3 of the stars are bright, mags 6-7, 5 others are 9...11. The nebulosity is brightest on the west side. The UHC does not help.

NGC 1980 Faint, large, irregular, not brighter in the middle at 100X. This nebula surrounds Iota ORI, the end star on the sword of Orion. If you are like me, the first time you looked at NGC 1980, you didn't know that you were looking at an object that has a separate designation from the Great Orion Nebula.

Granite Wash Mt. S=7 T=9, great night 13" 100X--pretty bright, pretty large, round nebulosity. 44 ORI is a triple star, involved in the nebula, there are 2 other pretty faint stars involved.

NGC 1981 Bright, large, scattered cluster of 28 stars at 100X. Double star Struve 750 on the NE side. Just north of the Orion Nebula.

Granite Wash Mt. S=7 T=9, great night 13" 60X--Cluster, very bright, large, not rich, not compressed, 23 stars counted from mags 8....12. Many bright members. It is just seen naked eye as a glow above the region of the Orion Nebula. 100X--3 of the brightest stars have nebulosity around them, this is most obvious for the stars on the East side of the cluster. 11X80 shows 7 stars in scattered cluster.

NGC 1982 (M 43) Bright, large, irregularly round, central star of 8th mag easy at 100X. This detached potion of the Orion Nebula is shaped like a fat comma. Going to 220X, there are several dark lanes across the face of this nebula.

Granite Wash Mt. S=7 T=9, great night 13" 100X--the "comma" shape is obvious, bright, large, irregular figure, bright middle, Star of 9th mag is involved, 2 stars of 11th mag. 150X--several dark striations in the nebula are noticed. One of the faintest stars invovled is right at the rip of a comma shape.

NGC 1990 Very faint, large, irregularly round, more easily seen with Epsilon out of the field of view, but never obvious at either 100X or 150X. I compared this nebulous star to Bellatrix, a star with no nebulosity, to see if light clouds or condensation on the eyepiece influenced my observation of nebulosity around Epsilon. There was always some nebulosity surrounding Epsilon in comparison to Bellatrix.

NGC 1999 Pretty bright, pretty large, round, somewhat brighter in the middle, stellar nucleus, with several dark markings at 220X. This object is brightest on the north side and averted vision makes it grow in size.

Ultimate Star Party, McDonald Obs., Oct. 95, S=7, T=9, 25" f/5--

NGC 1999 in 25" and 16mm is as large as the field of view and has several striations of light blue within the grey nebulosity. There are very faint connections of nebulosity that connect M42-43 to NGC 1999, I have never seen those before.

NGC 2022 Pretty bright, pretty large, round, somewhat brighter in the middle, a nice disk at higher powers. It was spotted at 100X, the central star was never seen, just a brightening in the middle. I called the color grey in the 13", using my old 17.5" Dobsonian at 200X I observed that this planetary was greenish.

Granite Wash Mt. S=7 T=9, great night 13" 100X--obvious dot. 220X--pretty bright, pretty small, little elongated 1.5X1 in PA 0. There is no central star at 220X. 330X--some difficult structure is seen, mostly averted vision only. The east side is consistently brighter than the west side. There are brief glimpses of a stellar spot offset to SE. All this detail is at the limit of the 13".

NGC 2023 Pretty bright, pretty large, irregularly round, this nebula is easily noticed at 100X without the UHC. There is a 9th mag star very near the center and an 11th mag star on the SE edge.

NGC 2024 Bright, large, irregular emission nebula near Zeta Ori. It is easy in any telescope I have ever used under dark skies and my old 8" f/6 would show several dark lanes winding across this nebulosity. The 17.5 incher brings out much detail in the region at 200X. Using the 13" f/5.6 at 135X with a UHC filter helps the contrast a lot and so does getting Zeta out of the field. Because of the large, parallel dark lanes, Arizona astronomers have taken to calling NGC 2024 the "Tank Track" Nebula.

NGC 2068 (M 78) Bright, large and fan-shaped. There are three stars involved in this nebula using the 17.5" f/4.5 at 100X. It is bright enough to be seen in a 8X50 finderscope. This nebulosity looks very much like an active comet, with a triangular glow that involves light and dark shading. I'll bet this guy has been turned into Brian Marsden as a false comet all too often. 6" f/6 on 6/10 night, with 14mm eyepiece it is pretty bright, pretty large and the comet shape is obvious. There is faint nebulosity out of the field of view is several directions.

NGC 2064 Faint, pretty small, round, not brighter in the middle at 220X.

NGC 2067 Faint, pretty small, round, not brighter in the middle at 220X. Both NGC 2064 and 2067 are near M 78 on the western side.

NGC 2071 Faint, pretty small, irregularly round, seen at 100X. Going to 220X brings out the fact that the star within this nebula is double. It is approximately 10th and 13th mag with a separation of 10" in PA 200 degrees. Averted vision makes the nebulosity grow and elongate in the E-W direction.

NGC 2112 Pretty bright, pretty small, somewhat compressed open cluster. In the 17.5" at 125X the cluster is well resolved into 40 stars and has one bright member with the rest of the cluster having a mottled "cottage cheese" effect.

Granite Wash Mt. S=7 T=9, great night 13" 150X--pretty bright, pretty large, pretty rich, not compressed. I counted 32 stars in the cluster, many faint. Stars are of mags 11..... Averted vision shows a few of the fainter membes. Most mebers are faint stars.

NGC 2141 Pretty bright, pretty small, very rich, very compressed, 46 stars counted at 135X. Averted vision shows a mottled background of stars in a very rich Milky Way field.

NGC 2169 Pretty bright, not compressed open cluster in the 17.5 inch at 100X. What is bizarre is that the cluster members form the numerals "3" and "7". It is a shame that this is not M-37, you couldn't miss it.

NGC 2174 Bright, large, much elongated 4 X 1 in PA 90 at 100X. This is a nice streamer with an 8th mag star on the north side. The UHC helps this nebula a lot. Using the filter there are several dark lanes which cut across the nebulosity.

NGC 2175 This cluster is marked as a large cluster on the south side of the NGC 2174 nebula. If that is so, then this object is pretty bright, very large, a scattered ringlet of 22 stars of mags 10 to 13. This is at 100X in the 13". However, there is a pretty bright, pretty small, very compressed cluster to the north of the 8th mag star about 10' of arc. At 220X from Sentinel on a 9/10 night it just resolved into 10 stars and a fuzzy background. This compressed cluster is not marked on Uranometria 2000.

NGC 2186 Pretty bright, pretty small, pretty rich, compressed at 165X. 27 stars counted of mags 10 to 13. This cluster is just seen in the 11X80 finder. There are several delicate pairs involved.

NGC 2194 Bright, pretty rich, compressed open cluster that is well resolved in the 17.5" at 100X. The cluster has a flattened shape.

Collinder 70 (Orion's Belt) Nebulosity around central Belt star is obvious, counted 70 stars of mags 7...10, not including the Belt stars themselves. There are many nice pairs and lots of bright members, the 38mm Giant Erfle just barely wide enough for it all to fit.

Binoculars Vicksberg Rd. S+T=7
8X25--22 stars in beautiful loops and chains around the Belt stars
10X50--52 stars in a WOW arrangement, gorgious loops or curving star chains, most of the star are piercing blue-white, some are yellow or orange, the binoculars show it all.

J 320 (PK 190-17.1_) Pretty faint, small, round, brighter in the middle at 320X. It was noticed at 135X, but it is better at higher powers. Averted vision makes this little planetary grow in size. It is very light green at all powers. I have observed this object several times and it is consistently about 3 times the size of the seeing disk, if the seeing is 6/10 or better.

IC 423 Faint, pretty large, elongated 1.5 X 1 in PA 0 at 100X. It is not much on a 6/10 night, just a field brightening.

IC 426 Faint, pretty small, not brighter in the middle at 100X. There is a 9th mag star on the west side, the UHC does not help this nebula.

IC 430 Faint, large, elongated 3 X 1 in PA 135 at 100X. This streamer of nebulosity has a fuzzy 10th mag star involved.

IC 432 Pretty faint, pretty small, round, just a fuzzy star at 100X, not much.

IC 434 and B 33 is a much-photographed region that includes the Horsehead Nebula (B 33). IC 434 is a faint streamer of emission nebula that is south of Zeta Ori. The Horsehead is a dark nebula that blots out a portion of IC 434 in the shape of a mare's head. I have seen the Horsehead in the 17.5 inch scope at 125X. With averted vision some light and dark detail could be seen, but it was tough. The Horsehead outline is small, maybe the size of the Ring Nebula.

IC 435 Faint, pretty small, round, just a fuzzy star at 100X. PK 197- 3.1 Abell 14 Sentinel S=7 T=9 13" 220X very faint, pretty small, round, not brighter in the middle. Just seen at 100X, better at 220X, but never easy. A low surface brightness disk, the UHC filter helps very little.

PK197-14.1 Abell 10 Sentinel S=7 T=9 13" Found at 150X, better at 220X. Pretty faint, pretty small, little elongated 1.2X1 in PA 165, very little brighter in the middle.

PK198- 6.1 Abell 12 Sentinel S=7 T=9 13" 220X Pretty faint, pretty small, round, little brighter middle. Just seen at 220X in the glow of Mu ORI. 330X helps the contrast, the UHC filter helps a lot, the glow is much larger and more contrasty with the filter.

Sharpless2-264 Buckeye 6/10 S+T 13" 100X--faint, very large, irregular figure, 15 stars involved 7....12 mags. The UHC helps a little. Some of the bizarre shape seen.
