I've done some prime focus as well as piggy-back stuff with the Celestron.
So far all is from my suburban light-polluted back yard. I have about 50
degrees of sky plainly visible. The rest I have to play peek-a-boo with the
trees most of the time. Limiting magnitute is around 4 :(. Still, its a
good time for me and the girls - my 9 y/o knows her way around the sky
fairly well. I recently acquired an ST-4 and off-axis guider to hopefully
improve the long duration exposures. Now if the clouds will leave during
new moon phase........
