Hi All
I'm just wondering if anyone here would be willing to tell me, What is the deffrence between a cassegrain and a gregorian reflector?

Hi All;
This New Year I'm planning on up-grading my old scope for a new one. And the choices and wide and varied now have an old dinamax 8" SCT. I'm looking for comments on a new scope and what you all think. I do like SCT scopes. The jump from an old 8" to a new 8" is not enough justification. So I must move up in size ;^) Also the new scopes have computers to drive them. Any thought for me to canister?

It sounds like you are seeing the secondary mirror. SCT do that if you use too long a focal length eye piece. On my 8" Dinamax the longest I can use is about 30mm or so.
good luck

Hi All
Any one know whats up with The
Astronomy Connection's web site it's been down for days now.

Hi All
I want to get in to CCD photography. And thought this is the place to get some advice on starting out. Just looking to fine out what to look for in a camera, I have an lx200 10” and a 208xt coming in the mail for guiding. So my question is what camera do you folk think I should get to start with and why? I’m looking for a camera that will make the learning process as painless as can be. I live in San Jose CA. so light dooms are a consideration. I’m looking for a starter camera. And I like to shop used if I can. thanks in advance
