A very cold night, made worse by my mistaking Alioth for Mizar, throwing out the whole alignment. This was compounded by not being able to focus the guide scope. I have mounted the telescopes on a larger rail , so that I can balance them better. While doing this I thought I could remove an extension tube (duh!). So, after an hour, scopes finally aligned and focused and aimed at The Whirlpool Galaxy, M51. The moon was half full and in Orion, so the sky as pretty bright. I was limited to 60 s exposures. This image is based on 118 minutes of data. Pretty pleased with it, considering!
