Description

I have no business shooting M51 with a short focal length camera lens but it was a work night with a pretty big Moon so I figured it was worth the experiment. Here’s the result after 3 hours of 3 minute unguided subs on a star tracker. A very modest image compared to most but it beats watching T.V.
