Seeing was pretty good, so I thought I would try and see if I could resolve some stars in NGC185. I was generally successful, but still think I can probably improve on this under better seeing and weather conditions.
Version A of the image is annotated, with several objects of interest identified, while version C is the full 16-bit version of the image. Eight globular clusters are know to surround this dwarf elliptical satellite of M31, which I have labeled as "GlCl". There are also quite a few small distant galaxies in the field too, some of which I have marked, where data was available in visible wavelengths. There is also a possible quasars that has the pale blue color that is common in many QSOs. I noted a 20.5 magnitude planetary nebula listed on the SIMBAD astronomical server that appears to be visible in the image, so I have also marked with a "PN". Several dusty molecular clouds can also be seen near the center of the galaxy.
Also, note the enigmatic galaxy UGC 378 in the lower right corner of the image. I have been trying to find any information on this very odd little object that contains a curious bright blue-green object. No luck yet finding any scientific papers or even images of it any better than this one.
You can see a list of some of the objects identified in the SIMBAD database within NGC 185 here:
http://cdsportal.u-strasbg.fr/?target=NGC185One thing that caught my eye was the large number of carbon stars (object type C*). These are intensely red evolved stars and may be the reason the galaxy appears to have a reddish tinge.
6 five minute images were stacked to produce this image with a total exposure time of 30 minutes. Each 5 minutes image was created by live-stacking 151 two second images in SharpCap 3.2.
