Viewed this last May in poor transparency 21.1 skies, without knowing what it was in advance. An example of how it pays to have done one's homework in advance, I would have spent more time to identify the HII regions. With a 20-inch:

"NGC 4395: Needed to switch to 121x for this one as it is large and spread out. Brighter almost stellar core area in middle of very faint, diffuse round glow uneven surface brightness. Probably a face-on spiral. Don't see any arms, just unevenness. [Turns out those uneven patches are distinct NGC designations, HII knots in the spiral]"
