Image From Another New Scope
I acquired a Celestron C 9.25 OTA in a trade a few weeks ago. Last night was the first time I got to run a camera through it, mostly due to weather. It has been one giant rainstorm for at least a month now. Last night was no exception. It was windy and had just rained an hour before. The sky was very turbulent, and lightning was flashing all about. I got the scope out anyway, because I wanted to try it out.
It did a fine job. Much better than I expected in the wind. It was taking 10 mph gusts, and it did not affect it much at all. I had it set to run at F3 with a little screw in focal reducer. I will have to put the regular F6.3 reducer in place and see how it works out. My focus was slightly off too. Overall not bad though.
The test image was of M27 with my old Starshoot CCD. Ten images at 5 minutes each.
