I found a 6 inch very handy
.
I now image thru it becuse it is a fast scope
.
If you can get to a star party you will know the one you want
...but you have to work up to those ones
.
Astro photography is not hard as it seems there are levels .. you can take snaps of the Moon and some planets by holding a camera to the eye piece of a dobsonian mounted scope.
I felt the best Moon shot I took was with a 2 meg camera at the eye piece thru a 6 inch refractor.. a fluke but you can get good shots that will let you know if photograpy is for you.. if it is just think mounts.mounts.mounts.. it starts there believe me
. The good news is the eq6 mount works and they are the first good cheap mount.. approx $2000
But you need a good mount... but for now buy a dob and enjoy it.. you wont regret it..
Best wishes and good luck
