Description

This is the results of last night's galaxy hunt. Only just over 4 hours of data but that is about the length of astrodarkness up here now. The moon was up but did not cause terrible trouble. I was first a bit dissapointed about the lack of structures in the arms of M90, but after looking at other images of this galaxy I realize that it has very smooth arms, with most of the structure found near the core.
