Since my processing technique gets better and the time of year doesn't give any support, I have reprocessed some older images. There is now star colors added and other processing is tweaked too.
NGC 281, in Cassiopeia
Ra 00h 52m 59.3s Dec +56° 37′ 19″
HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
NGC281 spans over 80 light years at its estimated distance of 9500 light years.
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.
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.

This is a personal vision about forms and shapes, based on my 2D-images, some known facts and artistic impression.
