Thanks so much for all the info Carl, Just to translate into Poita Speak to make sure I get it...
FL = Focal Length = 2000mm for my C8.
Which means it is like a monster zoom lens and has a very small FOV (Field of View)
So trying to track through it, I'll have buckleys that there will be a guide star close enough to what I am imaging. So I'd be better off with a small guidescope and guider to attach to the C8.
My best bet would be to get a guider pack from bintel that has a guidescope (Orion Mini Autoguider Package?) and a CCD autoguider thingy and I attach that assembly to my scope, and interfaces to my mount/computer?
Then I can either strap my DSLR with lens onto the C8 on the mount and take pictures of the sky that way, use the Nikon T-ring and extension tube to do eyepiece projection for planets etc. and can buy a CCD camera to start getting fancy.
If I want to stay at the 2000mm then a lower Megapixel camera would suit better like the Atik 314L.
If I want to shortern my focal length and widen my field of view, then a higher megapixel camera would be an option.
Have I got it right?
