Well, having received a Canon Digital Rebel for Christmas, I figured I'd give it a go with astrophotography. I've come to understand that I need a T-ring specific to the Canon and an adapter that will go with my focuser (1.25"). I was just wondering does this all mean that you don't use an eyepiece when using a T-Ring? I really don't understand the setup of it, and if anyone could perhaps provide pictures or a detailed description before I go out and buy the aforementioned items that would be great

Cheers, and hopefully I'll have some new pictures to post soon! (If the Chicago skies ever clear up...)

If you haven't already, look at CNC Supply for T-Rings and stuff.

As far as what you need to couple the camera, it all depends on the scope and camera. The lens on your camera is removable, so you can use a T-Ring to attach the camera body straight to a telescope. If you were to use a camera like mine, where the lens is not removable, than you could get a ring set that consists of the T-Ring, and another ring that attaches to an eyepiece.

There are a lot of other types of adapters, like Orion's SteadyPix, ScopeStuff's Universal Camera Adapter, etc.. But I'd say take a look at CNC Supply, and maybe give them a call and ask what's best for what you have.

Hopes this helps you

I'm confused, too. If you don't use a lens on your DSLR when you attach it to the scope, and you don't use an eyepiece in the scope, what magnifies the image for you to be able to take a pic?

I haven't done any prime focus photography yet, but I aim to. I have a T-ring and adapter for my Canon 40D DSLR. I understand a little more about PF AP than before, but only a little more. I'm still confused about the whole magnification thing. How does it magnify anything without the use of any lens or eyepiece? Are you stuck with one magnification power or is there some way to reach out further?
