A nibble at M101

[Uranium235]

This was my last target from last nights session. It was getting on a bit (I could hear birds already), so I took the decision to 2x2 bin my RGB subs. Guiding was a little more difficult on this one, maybe becuase I snagged the dec axis with my arm while fumbling about in the dark (doh!).

For the L subs, I decided to completely do away with LP filters. And to my surprise, I was able to get 10 min subs without any major wash-out. It certainly makes a case for not relying on LP filters so much.

Its not exactly a world beater, but its a start. I will return to it for extra L and colour unbinned.

Thanks guys If its clear tonight I'll get some more data, but the forecast isnt looking that great for this week. I need to get out again by the weekend otherwise the moon will start affecting any L subs i may take.
