from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Distance is about 10.000 light years. Image is about 30' wide and covers about 100 light years.
Ra 05 hr 28 min 05.9 sec , Dec +34 hr 25 min26 sec
This is not too commonly imaged target due the lowish surface brightness and the proximity of two eye catchers, IC 405 and IC 410. This image was one of the most difficult one to process due the very weak signal. There was some very dim O-III emission in the target, it can be seen as a Blue.
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations, 50% mix..
Levels, curves and color combine in PS CS3.
Telescope, Meade LX200 GPS 12" @ f5
Camera, QHY9 Guiding, SXV-AO @ 4,5Hz
Image Scale, 0,75 arcseconds/pixel
Baader H-alpha 7nm 22x1200s, binned 2x2
Baader O-III 8,5nm 4x1200s, binned 3x3
S-II is taken from my older wide field image
