I have been slowly acquiring gear to do astrophotography, much of it is in the mail still, but the other day I realized that I could mount my camera to my CG5 mount using a macro focus rail, which turned out to be a very sturdy and accurate setup.
Mount - Celestron CG5-GT
Camera - Canon T3i unmodded
Lens - Sigma 70-300mm APO
Aperture - F/5.6
ISO - 400
Exposures - 7x 1 minute 10 seconds, un-guided
Darks - 7x 1 minute 10 seconds
Flats - None. I really wish I had taken some, I had no idea I would have vignette problems with a camera lens!
Total Exposure - 7 minutes 10 seconds
Stacked with DSS processed in CS6 as 32 bit tiff
I am looking forwards to this week because my auto guider package, field flattener, and t-thread arrive so I can put my new refractor to use!
