Well last night I tried to find M51 and after not having it in view gave Astrotortilla a shot even though my daytime tests trying to get it to solve pre-existing exposures never worked... Well this time it worked *PERFECTLY*! Told me I was about 2 deg off my target. Even though having to manually adjust and re-run the solve a few times is not even remotely as fast as a go-to solve would have been it got me on target and imaging! If you ever have problems with finding targets for whatever reason - try Astrotortilla.
Even beter now that I was on target I was able to get my first ever useable run of 15min exposures! Guiding was not *perfect* (I need to adjust my polar align a bit) but it was good enough to have no rejected frames!
Anyway... just stoked about being able to actually *find* targets with a mount capable of driving the AT6RC successfully. Going to try for more time on M51 tonight but until then here is a crop of my quick stack and process of last night's 7 900s exposures @ISO 400 w/ no calibration frames at all.
(Edit: Hmm - I intended to post this in the DSLR imaging forum.... but hey, this is MOSTLY mount related anyway so may as well leave it here!)
