NGC 6640 Very faint, small, little elongated 1.2 X 1 in PA 160, very little brighter in the middle at 135X.
NGC 6675 Faint, pretty small, elongated 1.5 X 1 in PA 135, little brighter in the middle at 135X.
NGC 6688 Faint, pretty small, somewhat brighter in the middle, elongated 2 X 1 at 165X. In a very rich field of view.
NGC 6700 Very, very Faint, pretty small, round, not brighter in the middle at 100X. Averted vision helps a lot.
NGC 6702 Faint, small, little
elongated 1.2 X 1 in PA 60 and somewhat brighter in the middle at 135X.
NGC 6703 Pretty faint, pretty
large, little elongated, brighter in the middle at 135X. Has a companion
galaxy to the NW, faint pretty small, round and not much.
NGC 6710 Camp 613 S=7, T=8 13" f/5.6 100X-Just barely spotted at low power, 220X-very faint, small, little elongated 1.2X1 in PA 0, very little brighter middle, not much.
NGC 6720 (M 57) Bright, Large green ring with a "fill-in" across the ring structure. Central * seen occasionally. 36" at Kitt Peak 16 June 84, ring is so large and bright a 400X that the central * needs aviz, fill in effect obvious.
Ultimate Star Party, McDonald Obs. S=6, T=8, 36" f/5-- M57 16mm medium green, star outside ring is easy, central star is held about 20 percent of time. The "gauze across a hoop" effect is obvious and held steady all the time. The fingers of nebulosity that point inward from the Ring toward the central star are seen in moments of good seeing.
14mm + OIII some of the fingers of nebulosity OUTWARD from the Ring are evident with the 36" f/5 at TSP in 1996. I see them better with averted vision, but these low contrast neby can be held steady. The nebulosity is "blocked off" or rectangular in shape on one side of the Ring. Great view.
White Tanks site S=5, T=6 11X80 just seen as 9th mag star. 60X Annular even at low power--it is the Ring Nebula all the time! 150X Great view, bright, large, elongated 1.5X1 in PA 75 a lovely greenish donut is a nice starfield. The "gauze across a hoop" effect is obvious. 220x color is duller at higher power--a grey-green, but more detail is easier--the "gauze", outer neby, central star 5% of the time, SE and NW quadrants are brighter than the rest of the Ring. Go to all the power it will take.
6" f/6 Dugas S=5 T=6 14mm a delicate, elongated donut afloat in the Milky Way. No stars are very near the Ring--except one lonely, 13th mag Star to the East about 1 arcmin. The Ring resides in a dark area for about 10 arcmin all around.
NGC 6745 Faint, pretty small, elongated 2 X 1 in PA 0, little brighter in the middle. Averted vision helps at 165X.
NGC 6765 Pretty faint, pretty large, somewhat brighter in the middle, elongated 1.5 X 1 in PA 110. The UHC filter helps a little with the contrast of this object. There is a faint star on the NE tip, it comes and goes with the seeing. Camp 613 S=7, T=8 13" f/5.6 100X-easy to see disk is pretty faint, pretty small. 220X-pretty faint, pretty small, elongated 2X1 in PA 20, somewhat brighter middle, averted vision fills in the faint outer round shell. Grey in color at all powers.
NGC 6779 (M 56) Bright, pretty large, round, very compressed and very bright in the middle at 135X. Resolved 12 stars at 100X, high powers don't seem to bring out more stars. This nice globular is at the edge of the Milky Way and there is a dark spot next to it that is the same size as M 56. At Camp 613 at 220X, I can pick out 19 stars and a very grainy structure. There are very few outlying members of this compact globular. Ultimate Star Party, McDonald Obs. S=6, T=8, 36" f/5-- M56 with 16mm; 102 stars resolved, averted vision doubles the size of the cluster from un-resolved stars. Obvious group on North side.
Camp 613 S=7, T=8 13" f/5.6 11X80 finder-easy, pretty bright spot in the Milky Way. 150X-bright, large, irregularly round, pretty suddenly much brighter middle, much compressed, pretty rich. 16 stars counted, not in core, too compressed. In rich Milky Way field. 330X-30 stars counted, core is somewhat triangular in shape, nice view, averted vision fills in the shape to round.
Sentinel 8/10 S+T 13" 11X80 just seen in rich field. 100X--bright, pretty large, irregularly round, very much brighter middle and much compressed. 10 stars counted, the bright core is somewhat triangular. 220X--22 stars counted, still a triangular core, averted vision makes it very much larger at the edges. 330X--34 stars counted, not so much averted vision growth effect at higher power. A pretty bright yellow star on the NE edge of cluster is near a thin dark lane with this compact globular.
With the 6" f/6 RFT and a 22mm Panoptic that give about 40X this compact globular cluster really swims in the Milky Way. I saw it as bright, large, round and much brighter in the middle, an obvious glob even at low power. There is a pretty bright star (about 9th mag) on the west side of the cluster. Raising the power to 100X with an 8.8mm Meade UWA will resolve 6 stars at the edge of this cluster. There is still a fuzzy central section. Averted vision will show about 20 more very faint stars that are at the limit of the 6 inch scope. These faint members were never held steady at the higher power.
NGC 6791 Pretty faint, pretty large, little elongated 1.5 X 1, Faint open cluster that is just a bright spot at low power, resolved a dozen stars at 100X. Another observation from Camp 613 brings out 38 stars counted at 135X. From the better site I called it rich with lots of dim members. Camp 613 S=7, T=8 13" f/5.6 11X80 finder-just detected as faint glow. 100X-pretty bright, pretty large, somewhat compressed, 12 stars counted with "oatmeal" glow in background. Light yellow star "U LYR" on northern edge. 150X-cluster aspect almost gone, tough to see edges of cluster, counted 22 stars as members, 5 are extremely faint, averted vision helps cluster stand out.
With the RFT and a 22mm Panoptic that give about 40X, this cluster is just a fuzzy spot in the Milky Way. I saw it as faint, pretty large, not brighter in the middle and has three stars resovled. Using an 8.8mm eyepiece will resolve 6 stars and make the fuzzy cluster larger and more obvious. Never a showpiece with the 6 inch.
NGC 6791 Eagle Eye Rd. 13"
S=6 T=7 after Moonset
NGC 6792 Faint, pretty small, elongated 1.5 X 1 in PA 30, somewhat brighter in the middle at 165X.
PK 56+14.1 Extrememly faint, pretty small, round, very low surface brightness with 2 very faint stars involved. Sentinel 7/10 with 13" at 100X. UHC no help, too faint. "you have got to have some photons to filter".
PK 64+15.1 Faint, small, round, central star seen occaisonally at 220X. The "other" planetary in Lyra is not much a needs 135X to find it even at Dugas Rd on a 7/10 night. On another observation I saw it as little elongated in PA 0.
Isk 1 No obvious cluster at this position, the Milky Way has no lumps at 60X.
Steph 1 Bright, pretty large, not rich, not compressed, about 15 members seen at 100X. Delta LYR and 15 faint stars involved.
Beta LYR Wide double, white and light blue, several other pretty faint field stars.
Delta LYR Split in 11X80 finder, at 100X white and light yellow.
Zeta LYR Wide at 100X, white and light yellow.
Struve 525 Wider pair split at 100X, yellow and blue, close pair splits and makes it a triple at 220X, clean division 10% of the time.
Struve 2349 Split at 135X, white and light blue. On a different night I saw light blue and light orange.
Struve 2372 Split at 100X, white and light blue.
T LYR Reddish-orange pretty faint star at the edge of the Milky Way. Another observation, lovely coppery red afloat in the Milky Way.
HK LYR Dark orange at 100X.
