Soul Nebula closeup
Nebula in natural color. Narrowband channels are mixed to match visible spectrum. Red=80% H-alpha+20% S-II, Green=O-III and Blue=80% O-III+20% H-alpha to compensate otherwise missing H-beta.
Nebula in HST-palette, Red=S-II, Green=H-a and Blue=O-III
The nebula season is kind of over but up here, 65N, it's still very possible to shoot some nebulae.
The Soul nebula, IC 1848, was in western sky at elevation of 55 degrees when I started imaging, at Nine a clock. I took last images at four in a morning, at that time the elevation was about 30 degrees and it was just past the Northern moust point at a sky. Evem though I spen whole night shooting this, poor transparency, speeding clouds and, due previous, lost guidestar, I was able to use only Seven 20min. frames for this.
Color for the final image are taken from my older narrowband image from 2008, the original Blog post can be found here: http://astroanarchy.blogspot.com/2008/10/heart-soul.html
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.

An anaglyph Red/Cyan version.
You'll need Red/Cyan Eyeglasses to be able to see this image right. Note, if you have a Red and Green filters, you can use them! Red goes to Left eye.
