Description

M99, found in constellation Coma, is about 5' across and has an apparent brightness of ~10 mag. Surprisingly there don't seem to be very many images of it on Astrobin, despite its relative brightness. I find it striking how similar to m101 it appears, although much smaller

I'm still getting my setup honed in after switching to my Edge HD for galaxy imaging, so corner stars are suffering a bit. Hopefully next week I'll fix my back focus.

Attached as revisions are annotated and inverted versions. Most of the smudges are galaxies in the inverted one!

Thanks for looking and clear skies
