NGC 185 is a dwarf spheroidal galaxy lying 2.08 Ml light-years. It is located in the constellation Cassiopeia and is a member of the Local Group of galaxies.
It is also a satellite galaxy to the more famous Messier 31 aka Andromeda spiral galaxy.

This picture was captured on 2019-10-30 during clear weather conditions from East Cheshire in England. I used my Altair Wave 115 EDT with an Atik 428ex to capture eight fifteen-minute guided exposures. This is a work in progress, as I want to add more data when the weather conditions allow.

Stacked in Deep Sky Stacker, with processing done in ST and PS CS5.

I've labeled a couple of globulars clusters within NGC 185 on your image.

This is very high-quality data, Paul!

Steve, are these globulars observable visually?

My observation of NGC 185 and two globular clusters with my 20” telescope:

At 83x I see a very large ellipse with a stellar core. This galaxy is much easier to see than nearby NGC 147 (which also has a stellar core). At 545x and 692x I occasionally see Hodge 5 pop into view about 25% of the time. Along the long axis just outside of the galaxy in the direction of Hodge 5 I saw a faint star. Along the short axis just at the edge of the galaxy on the side of Hodge 5 I see a fuzzy star. That's Hodge 3. A bit further outside on the same side lies but slightly away from Hodge 5 lies another faint star. I found Hodge 3 easier than Hodge 5. Hodge 5 appeared to me distinctly stellar while Hodge 3 appeared fuzzy. In general I find faint fuzzies easier to see than faint stars.

Great stuff. Here is a good reproduction of the original Hodge chart that I found in Jstore:

Thank you for all your kind comments.
Thank you Steve for showing these globulars that, I didn't know about.

I wanted to add that object #2 in Hodge's chart has been reclassified as a galaxy -- specifically, LEDA 2318158 = 2MASX J00385452+4828030. It was rejected as a globular cluster back in 1977 by Ford, Jacoby and Jenner in http://articles.adsabs.harvard.edu//full/1977ApJ...213...18F.

The V magnitude of this galaxy is ~16.2. In my 24-inch at 325x and 450x it appeared very faint, round, ~12" diameter. It was nearly attached to a mag 14 star at the SW edge. A mag 12 star was also less than 30" SW. I also glimpsed it in a 17.5-inch scope, but it was tough.
