Hershel 400 Objects in Corvus


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
4027 CRV GALXY 11 59.6 -19 15 11.7 3.0'X2.3' H II 296 Pretty faint, large, elongated 1.5 X 1 in PA 110 and much brighter in the middle at 220X. This galaxy exhibits some nice mottling in the outer section. What I found bizarre is that the central core of this galaxy is elongated in PA 75, much different from the angle of elongation of the main galaxy. I cannot think of another example of an object with a bright core that is skewed in relation to its' main body.
4038 CRV Sp 12 01.9 -18 51 10.7 2.6'X1.8' H IV 28 Pretty bright, pretty large, irregularly round and somewhat brighter in the middle at 100X. Going to higher powers reveals some of the bizarre nature of this extraordinary galaxy pair. The "shrimp" or "comma" shape of the two interacting galaxies is evident at 165X and 220X. There are several small dark features seen and the entire galaxy pair is very mottled, almost like a sponge, at high power.
4361 CRV PLNNB 12 24.5 -18 48 10.3 80" H I 65 Bright, large, somewhat elongated (1.5 X 1) in PA 90, grey in color at 135X. The central star is obvious at all powers. Going to 220X brings out an almost "mottled" effect across the face of this planetary nebula, a strange effect for this type of object. Most planetaries I have seen appear smooth at high powers, this one does not.
