What a great comparison shot Ving..that was really helpful!
Thanks guys - with a bit more elevation it would have been a lot sharper. Yeah..Ice..thought I'd throw one in from left field.
Tony (Itchy)- Some seriously good DSO shots on your website mate whew!
Paul - Yep the Mintron starlight function performs very well as Mick Pinner has recently been discovering. I have a few other samples of video DSO stuff on my webpage

I can basically just fit NGC253 diagonally across the 1/2" CCD model with the 10-inch at f5 and the 1/3" model is great for smaller targets.
