Personal "rating" this aperture: C
Small, and very bright with an intense
core, so much so that I thought this was
a defocused star. Very, very close to another
galaxy, I believe perhaps NGC3990 which looked like
a small elliptical, round, dim, featureless..
3998 appeared as a fuzzy star with weak nebulosity
surrounding it. Took me a moment to realize it was
a galaxy.
Will have to revisit this and the cluster of galaxies
nearby.
