Telescope & Camera

    Hey all,

    A friend and I are thinking of getting a telescope, and we've been looking at the Celestron Nexstar 127 SLT. We'd love to be able to hook our cameras up to the telescope, and take photographs, but we're a little confused about this. We both own digital cameras with 58mm lens, and we assume the 25mm eyepiece is for cameras - but how do we hook them up when the lens on our cameras are bigger than the eyepiece?

    My friend had a telescope years ago, but it wasn't a computerized one and he's as much a novice when it comes to 'scopes as I am. So, we'd like a little advice, please. I'm interested in looking at the planets, while my friend is interested more in the stars - split right down the middle when it comes to telescopes, as far as I can see.

    What do you guys recommend, and can you clear up our confusion on the camera issue?

    Normally aperature is king in astronomy but astrophotography may be the exception... good quality optics and a modest aperature is ideal for a starter in astrophotography.

    A small aperature refractor of between 70mm to 80mm with a focal length of between 400mm and 500mm is an ideal choice for you.

    Also do bear in mind that for astrophotography the mount is as important as the scope!

    You'll also need a field flattener if you use a small refractor - covered in link from Linguo (I think).

    Something like the following would be a good choice:

    but remember to budget for eyepieces, diagonal and not forgetting the mount...

    Also, if you are serious about astrophotography check out Jerry Lodriguss - he has a CD book "A Beginner's Guide to DSLR Astrophotography" available online - sounds like it was written for you :)

    BTW the "25mm eyepiece" refers to the focal length of the supplied eyepiece - used for visual astronomy or eyepiece projection.

    Hope this helps.
