Rohan, prime focus is the telescope without an eyepiece, and the camera without a lens. So yes, the telescope becomes a very large telephoto lens.

What it sounds like you were doing was afocal, where you still have an eyepiece in and the lens is still on the camera too.

Focussing at afocal can be hard, try a longer focal ratio in your camera settings, and set focus to infinity on the camera. The rings and adapters will help because the camera will be lined up better.

Ken, yes you'd need a laptop, or your desktop very close to your scope which is usually unlikely. You can get some cheap laptops off ebay, but yeh it's gonna cost around $1000 by the time you buy a ToUcam as well.

Start with afocal, i've seen some very nice results this way.
