Hershel 400 Objects in Sagittarius


Abbreviations in the CON column are the IAU versions.
The column TYPE has following abbreviations:
OPNCL = open cluster PLNNB = planetary nebula GLOCL = globular cluster CL+NB = open cluster and nebulosity BRTNB = bright emission or reflection nebula
Hubble Classification for galaxies or GALXY where no classification existed.

In the Herschel Column the Classes are:
I = Bright Nebulae III = Very Faint Nebulae V = Very Large
Nebulae
VII = Pretty Much Compressed
Clusters of Large or Small Stars
II = Faint Nebulae IV = Planetary Nebulae VI = Very Compressed and Rich Clusters of Stars VIII = Coarsely Scattered

Observation Notes
6440 SGR GLOCL 17 48.9 -20 22 9.7 5.4' H I 150 is a rich globular cluster, pretty bright, pretty small and much brighter in the middle. It had ragged edges with 10 stars resolved.
6445 SGR PLNNB 17 49.2 -20 01 13.0 35"X30" H II 586 is a nice planetary, 20 minutes North Following 6440. It is pretty bright, Large and has a box shape at 200X. It shows a small dark lane at high power and is definatly not a 13th mag object as listed, I estimate 12.
6514 SGR CL+NB 18 02.3 -23 02 6.3 28.0' H V 10/11/12 & IV 41 (M20) Very bright, very large, irregularly round, approximately 40 stars involved in a nebula that is criss-crossed by dark lanes. The Trifid is naked eye from even a moderately dark site. The UHC filter enhanced the nebulosity, but I like the view of this object better without the filter.
6520 SGR OPNCL 18 03.4 -27 54 7.6 6.0' H VII 7 is a pretty bright open cluster but it is pretty small with about 20 members at 165X.
6522 SGR GLOCL 18 03.6 -30 02 8.6 5.6' H I 49 and 6528 are two globular clusters right at the tip of the spout of the Teapot. I see both as Pretty bright, pretty large, and bright in the middle. They reside in a nice MilKy Way field. What doesn't in Sagitarrius?
6528 SGR GLOCL 18 04.8 -30 03 9.5 3.7' H II 200 and 6522 are two globular clusters right at the tip of the spout of the Teapot. I see both as Pretty bright, pretty large, and bright in the middle. They reside in a nice MilKy Way field. What doesn't in Sagitarrius?
6540 SGR OPNCL 18 06.3 -27 49 14.6 0.8' H II 198 Pretty faint, small, round, not rich, very compressed at 165X. Three stars are resolved constantly and another 3 or 4 come and go with the seeing at 220X. This very compact cluster demands high power.
6544 SGR GLOCL 18 07.3 -25 00 8.3 8.9' H II 197 Pretty bright, pretty small, round, very compressed, 7 stars resolved at 220X. Averted vision makes it grow.
6553 SGR GLOCL 18 09.3 -25 54 8.3 8.1' H IV 12 Bright, pretty large, much compressed, round, about 4 stars resolved at 135X. Averted vision helps.
6568 SGR OPNCL 18 12.8 -21 36 8.6 13.0' H VII 30 Pretty bright, large, pretty rich, somewhat compressed, 33 stars within 10 arcmin at 100X, a nice globular of pretty faint stars.
6569 SGR GLOCL 18 13.6 -31 50 8.7 5.8' H II 201 Bright, large, round, resolved 12 stars with a very grainy backround at 165X.
6583 SGR OPNCL 18 15.8 -22 08 10.0 2.8' H VII 31 Pretty faint, pretty small, round, compressed, not rich, counted 12 stars at 220X.
6624 SGR GLOCL 18 23.7 -30 22 8.3 5.9' H I 50 is bright, pretty large and round. It has a very bright middle and is resolved at 165X. This a nice globular that doesn't get looked at much.
6629 SGR PLNNB 18 25.7 -23 12 10.5 16"X14" H II 204 Pretty bright, small, round, central star seen at 270X. This light green disk is about three times the Airy disk on a night I rated 8/10.
6638 SGR GLOCL 18 30.9 -25 30 9.2 5.0' H I 51 is pretty bright, pretty small, round and much brighter in the middle. I could it to look very grainy, but it would not resolve at any magnification up to 320X.
6642 SGR GLOCL 18 31.9 -23 29 8.8 4.5' H II 205 is a pretty bright, pretty small globular that is somewhat elongated and very compressed with a bright middle. It is resolved at 165X.
6645 SGR OPNCL 18 32.6 -16 54 8.5 10.0' H VI 23 Bright, large, rich, pretty compressed, 49 stars counted at 100X. This cluster is in a bizarre "donut" shape with no stars in the center of this grouping.
6818 SGR PLNNB 19 44.0 -14 09 10.0 22"X15" H IV 51 is a bright, pretty small and little elongated planetary. It is green at all powers. At 320X is looks somewhat like the CBS eye, with a subtle central bright spot that was never stellar. Three dim stars surround the nebula.
