An undevout astronomer is mad.

My astronomy sketches. Hover mouse over image for the inverted look. For fainter objects, take a look at the black-on-white original, sometimes it reveals more details.

Description:

NGC 3184 is much brighter, a perfectly round, face-on galaxy, while its companion is a much fainter nearly edge-on galaxy dancing on the border of direct visibility. The 3184 has a brighter core that isn't round but rather amorphous, and features a brighter arc on the SW side of the galaxy. Later by checking photos I've found that these are all spiral features, it's a really exciting object. NGC 3179 has an almost star-like core, with a real star nearby.
