Description

I'm having fun finding Galaxy groupings. Although this image may be less dramatic than my previous post of NGC 4535 and M 49 Widefield, this image came out cleaner; most likely for two reasons. 1) I remembered to lower the ISO after adjusting position and focus. 2) I was able to acquire a longer integration.

Thanks for looking!
