Crab Nebula

These shots of the Crab Nebula (M1) were made a year ago (11/11/2010) but we had no time to process them before.

We took the stills in Churriana de la Vega (Granada) and through a Skywatcher 80ED + QHY9 monochrome CCD and a  EQ6 mount:

• 1x1 binning luminance: 19 shots of 300 seconds
• Color is formed by:
• 2x2 binning H alpha: 8 shots of 300 seconds
• 2x2 binning Oxygen III: 8 shots of 300 seconds
• 2x2 binning Sulfur II: 8 shots of 300 seconds
• TOTAL: 3 hours 35 minutes
• Processed with ImagesPlus + Gimp
