HI

I would like some comments on getting a Celestron 9.25" or 11".

1) What is the difference in between the two, I would like to get into taking deep sky objects, comets and planets. I know I need a guide scope. I do know you need to spend a few hrs doing stacking on the photos, does size make a difference in the end result?

2)What is the difference in between the CGEM and CGEM DX mount for astrophotography. Their is a few hundred dollar difference.

3) I do have a few barlow lens from my old 6" scope, a 2x and 3x, do people use them on their CCD cameras?

4) I live in Katoomba in the blue mountains, west of Sydney, so I do have ok dark skies.

5) If their is no difference between the two, is it better for me to get the 9.25" EdgeHD? As almost the same price as a normal 11".

I hope a have covered the basics.
