The problem will be Ken if your trying to view through a scope mounted on your dob (image with the dob) then you will probably end up touching the mounted scope which will cause your image to move while your recording through the dob. If I'm imaging planets (been a bit slack on that front lately

) I will often spend some time observing visually, keeping a close eye on the seeing. If it looks like the seeing is improving I'll pop in the ToUcam and whip off a few avies, then go back to visual. If I notice improving even more I'll whip off a few more. This is with tracking though so I imagine you're going to have some fun for a while. I think you need to have a bit of a chat with the Dob Imaging King, His Royal Iceman.
