NGC 7000, the "North America" nebula closeup

Close up of the NGC 7000, the "North America" nebula.
Image is composed from O-III and H-a narrowband channels to a bi-color image.
This palette is close to a visiblel spectrum.I'll shoot more O-III and S-II for this, to build a HST-palette image, later.


Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations.
Levels, curves and color combine in PS CS3.

Telescope, Meade LX200 GPS 12" @ f5
Camera, QHY9 Guiding, SXV-AO @ 6Hz
Image Scale, 0,75 arcseconds/pixel
Exposures H-alpha 15x1200s, binned 1x1=5h
O-III 1x1200s binned 3x3
