Astro Photography Help

I picked up a universal 1-1/4 T-adapter and the T-ring for my camera. Now
when attached to the scope I try to focus and I run out of travel. Am I
doing something wrong? my scope is a celestron 4.5" newtonian. Thanks John

Hej John

It's normal on a reflector telescope. I have moved my primary mirror closer
to the camera (nearly 2 inch), but then I can't focus with my eyepice
without an adapter. I use a cheap barrow without lens as adapter.

Good luck
Carsten
