Date: August 25/26 2011
Location: LB Pearson College of the Pacific, Metchosin, BC.
Equipment: Telescope: Astrotech AT8RC, Mount: EQ6 autoguided with Orion Autoguider camera and PHD software.
Imaging Camera: Orion SSPro, v1, MaximDLE software
Exposures: Lights - 12 X 600 seconds, Darks - 3 X 600 seconds, Flats 12 X .30 s using an electroluminescent panel and 12 Bias frames processed with ImagesPlus and PhotoShop.
Note: I redid the Helix to get rid of the dust motts (dark doughnuts) in the image by using flats of a shorter exposure.
