Description

My first mosaic and submission to the Cloudynights.com Beginner and Intermediate Imaging Competition. This is a two panel mosaic and my first attempt with longer focal length imaging. I ran into a few issues with guiding and focusing and by the time everything was sorted out some overcast weather rolled in for the remainder of the month. This will absolutely be updated once I am able to get more data.
