Apart from Andromeda, most galaxies are quite small in terms of angular size.
My 80mm refractor is quite a modest scope but I was keen to see what I could make of the Whirlpool galaxy M51 and its companion NGC 5195. The two are interacting gravitationally, with the larger M51 pulling material from the smaller NGC 5195.
Some other galaxies are visible in the field of view. I think the 2 spirals to the NE (if N is at the top) are IC 4263 and NGC 5169. Small elliptical galaxy NGC 5173 is just beyond NGC 5169.
Directly E of M51, the small fuzzy blob is the elliptical galaxy NGC 5198.
Integration of 5 x 60 secs, 4 x 300 secs and 2 x 600 secs (45 minutes total).
