Herschel 400 Objects in Aquarius


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
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
Clusters of Stars
Observation Notes
7009 AQR PLNNB 21 04.2 -11 22 8.3 28"x23" H IV 1 is the Saturn Nebula, a famous planetary with outer ansae (wing-like projections) and a bright inner disk. It was discovered by William Herschel in 1782 but Lord Rosse was the first to see the extending ansae. The projections reminded him of the planet Saturn and he gave this object its' nickname. Amateurs have been trying to duplicate that observation ever since. The observation of the Saturn Nebula is made with Helen and Richard Lines' 20" f/6 Newtonian in Meyer, Az. The nebula is bright, small, somewhat elongated and light green at 150X. Raising the power to 225X will show the ansae as faint projections from the bright central section. At 400X the central star is obvious and the ansae stand out more clearly. One of the bright spots along the ansae (Helen Lines calls them wing tanks) is visible at this higher power. All these observations are on a night I rated 7/10 for seeing and transparency and I found that the U 7009 UHC filter did NOT help with either the central disk or the ansae detail. Several observers, myself included saw the nebula as light green, without the UHC filter installed.
7606 AQR GALXY 23 19.1 -08 29 11.5 5.8'x2.6' H I 104 Pretty bright, pretty much elongated and brighter in the middle with a stellar nucleus at 165X.
7723 AQR GALXY 23 38.9 -12 58 12.0 3.6'x2.6' H I 110 Pretty faint, pretty large, somewhat elongated. It has a stellar core at 100X. The core is about 10" in size at 220X.
7727 AQR GALXY 23 39.9 -12 18 11.5 4.2'x3.4' H I 111 Pretty faint, round, pretty bright nucleus, averted vision helps the contrast of this galaxy. There is an attendant galaxy about 20' to the West. I believe it is NGC 7724.
