Here's an image of the Crab Nebula using data taken by Adam Block with the Schulman 32-inch RCOS Telescope at the Mt. Lemmon Skycenter in November and December of 2012, from Adam Block Studios Cosmic Canvas.  I hope I did the data justice in the processing of this image.....the calibrated master bias, darks and flats were done with CCDStack and, of course, I use Pixinsight, so that was a bit of a problem to get the RGB and Ha images to calibrate.....but I finally figured out how to do it.  There's 5h 45min of RGB @900s/sub and 11h of Ha @1800s/sub.   It's GREAT quality data and once I got the frames to calibrate, it was a heck of a lot of fun to further process.
Anyway, hope ya like it!
