Thanks Merlin66, yes I am at prime focus using a T/Ring on the Camera Body. If that is the case I will have to get a different Camera or Scope. I was thinking that one day I would like to own a 14" Meade SCT? but that's a long way away and looks like I will have do some extra trial with both Camera's to see which will give the better end results. bugger. I could try for a different CCD but it could cost a bit.
I had a thought that maybe Drizzle might double my pixel resolution if the software supports it at capture with the aid of a Guiding Camera. Is this the same as Dithering as I saw motioned in APT.???
