Two Dwarfs (spheroidal galaxies)

NGC 147 (right) and NGC 185 (center) are two dwarf satellite galaxies of the Great Andromeda galaxy. Both are approximately 250 Kly from Andromeda. For comparison, the Magellanic Clouds, our most prominent satellite galixes, are 160 & 200 Kly away (LMC and SMC, respectively) from earth.

At an approximate distance of 2.1 and 2.5 Mly from earth, for NGC 185 and 147, respectively, both posses low surface brightness.

The brighter of the two, NGC 185, can be observed using a 10 in. Newtonia under moderately light polluted suburban skies.
