Cheers Beren. It's an interesting tradeoff between length of the sub and having enough of them to get good S:N. Meade recommends 50 or more images stacked so going for more than 1 min subs makes for a very long night when you are looking to get RGB.
Alex - should be interesting to see how the C11 goes on the EQ6. My Motofocus arrived today so I'm expecting clouds for the next two weeks - sorry!
