M57 The Ring Nebula. North is up. - Frank Marks (frank)

Description

:

2 minute x 5 exposures using a Canon Rebel T2i DSLR camera mounted at F11 focus on my Celestron CGE 1400 with tracking equatorial mount. An Orion Starshooter ccd camera was attached to a piggy backed 150mm F12 mak telescope for auto guiding during the exposure. I used Maxim/DL Pro5 software from Diffraction Limited to process the picture. Than I used Neat Image to further reduce noise in the image.
