M101 is not easy - especially those really faint arms.

It needs a lot more data than 75 minutes!!

A good start though.

I'd say that was pretty good for 75 mins of data but there's a bit of a wierd colour cast - too much green I think.

Thanks for the kind comments. I knew it was a dim target so I planned 20x 300s and 10x600s though the 10 minutes subs would be finishing after it started getting light. But the guiding stopped.  Everything else kept working except the ASCOM connection to the mount.
