:

30 sec. x 3 exposures using a Canon EOS 20D SLR digital camera mounted at F2 focus on my Celestron CGE 1400 with tracking equatorial mount. HyperStar adapter was used. No guiding was used during the exposure. I used Maxim/DL CCD software from Diffraction Limited with Max Eos driver software from bearcreekobservatory.com to process the picture.
