NGC 7000 closeup in HST-palette NGC 7000 in HST-palette from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen. HST-palette colors are borrowed from an older, wide field image of North America nebula. I'll shoot new, high resolution, color channels for O-III and S-II, when ever weather up here allows me to do so. Technical details for the older image, from 2008, can be found here: http://astroanarchy.blogspot.com/2008/09/my-first-ever-narrowband-color-image.html (This is actually my first ever narrow band color image!) Technical details for closeup: 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
