I observed the Deer Lick group and Stephan's Quintet two years ago, with my 3" refractor from my suburban NELM~5 backyard.
I could not see the galaxies in the Quintet using glass only, but at 110x using live video I noted: "I can easily identify the two central galaxies NGC 7318A-B, as a pair of faint fuzzy “eyes”. The galaxies NGC 7317 and 7320 each appear as a pair of stars, where one “star” is fuzzy (the galaxy) while the other is a foreground star from our own galaxy. Finally NGC 7319 can be spotted as a faint, hazy spot, while NGC 7320c is too faint to be detected by my equipment".
I've posted my observation including drawing of the Quintet here: https://www.cloudyni...-ngc/?p=7635066
In the Deer Lick group, I could see NGC 7331 (the "salt stone") as a faint hazy spot at 24x, and the three "deer" NGC 7337, NGC 7340 and NGC 7335 as fainter companions at 110x (using live video). It seems I didn't post that observation at CN (in the "Classic Best NGC" thread), so I'll include it here:

_______________________________________ COMMENTS _____________________________
It is late October, and after two weeks of cloudy autumn nights (and days), there is now finally a cool, clear evening with the first stars peeping out; The transparency is however below medium due to high atmospheric humidity (haze), so the NELM is only around 5m (SQM 17.9).
My target for tonight is NGC 7331 (RASC 3). I start my star hop from Beta PEG (Scheat), then 5° NW to Eta PEG (Matar), that forms a nice wide bino double with Omicron PEG. Right between Omi PEG and Pi PEG (7° further up NW), there is a pair of ~6m stars, the brightest being 38 PEG. From 38 PEG I now pan the telescope 3° UP NE to a close pair of ~6m stars. This is my anchor for the final hop to NGC 7331.
Placing my ‘anchor’ pair of stars at the N edge of the 1.7° FOV of my K-40mm finder eyepiece (24x), there’s a Zig-zag line of stars down a good 1° S to a pair of 9m stars, just SW of the center of the field of view. NGC 7331 is 15’ SE of this pair, and is seen as a faint hazy spot at 24x in the finder eyepiece. Clicking up the magnification …
For more detail, I now click over to live video, using my R2 ccd/lcd, which yields 110x in a 0.3° FOV; NGC 7331 is immediately revealed as a very beautiful galaxy, clearly elongated in the SSE-NNW direction. I can see its bright, elliptical bulge (a good 1’ in the long axis), with a central stellar nucleus, that is offset towards the W (caused by the galaxy’s 22° tilt from edge on). The W edge of the galaxy clearly fades away more abruptly than the E part (due to a prominent dust lane), and I can glimpse a thin, dark dust lane crossing the galaxy to the S of the bulge. The galaxy also shows a dim, elliptical outer halo, but this is without any structure at my current 110x magnification.
In the same field of view as NGC 7331, I can also with some effort (and knowing where to look) distinguish three other, very faint hazy spots, indicated on my drawing as: 1 (NGC 7337), 2 (NGC 7340) and 3 (NGC 7335). These – together with the fainter still #4 (NGC 7336, which I did NOT see) – constitute the “Deer Lick Group” of galaxies, where NGC 7331 is imaged at a salt stone and the other NGC galaxies are seen as deer. While the “salt-lick” is a relatively close neighbor (47 MLY), the “deer” galaxies are ca 10 times as far away (280-400 MLY), and thus much smaller and fainter compared to NGC 7331. [Other imaginative amateurs have seen NGC 7331 as the deer, and the smaller NGCs as fleas, but I prefer the Deer Lick description].
To verify my sketch of the group, I take a snapshot of the R2 image. Later at the computer, I am able to verify the capture of the three deer, and - just for the fun of it - I can also identify 4 double stars, that have been classified as NGCs (presumably in the belief that they were proper DSOs).
Info: NGC7331 is found 4½° NNW of Eta (η) Pegasi. It is a spiral galaxy, tilted 22° from edge on, of type Sbc (ie. with somewhat tightly coiled arms, a relatively small nucleus, and no bar).
