M101 17th April 2010.

Thought I'd try something different tonight.
Here is 2 Hours 40 Minutes of M101.
It's really big! fills the whole image frame. But It's really dim, mag 7.5 compared to M51 which is mag 8.4, doesn't sound a lot but it is when you're imaging.
This is a very quick process minus darks... because I'm still creating them!
5 Minute subs, prime focus C9.25, PHD guiding, works a treat :-) even when the guide scope is crashing into the side of the shed!!! :-0
