I am jsut a beginning astronomer and astrophotography is quite demanding. But this I an pround of. Thanks to the Celestron CPC11 our school has bought and a pentax K200D DSLR courtesy of Pentax Canada, I was able to take this picture of comet C/2009 R1 McNaught at 2:00 am. Had to get to the top of a mountain to get above the fog. This is a 2 minute exposure at ISO 1600.
