M27 the Dumbell Nebula part Deux.

M27 the Dumbell Nebula part Deux.

Another attempt at M27. A visiting friend was so taken by astrophotography at the Metchosin star party that she wanted some data to take home to try stacking/proocessing. We shot M27 from my backyard August 15 2010. This is my end result. I'm looking forward to hers.

Telescope: W.O. Megrez 90 on Synta EQ5 GEM. Unguided.
Camera: unmodded Canon Digital Rebel XTi at prime focus, ISO 800, using Canon Utilities and Zoombrowser EX camera control/image capturing software.
Exposure: 20 x 30s lights, 10 darks.
Processing: Deep Sky Stacker, PhotoShop 6 for contrast stretch, curves and levels, colour balance, unsharp masking. Irfanview for TIFF-to-JPEG final conversion.
