IC 443, a prewiev version in HST-palette
IC 443, HST-palette
I have shot this target with much wider field last year;
http://astroanarchy.blogspot.com/2009/02/ic443-in-hst-palette.html I took colors from this image and use them with my new H-alpha channel to build a kind of prewiev version of narrowband color image.
When weather allows, I'll shoot better color channels with a native focal lenght.

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

Planetary Nebula, PK 164+31.1, more lights
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.
At the same time as I was imaging IC 443 in prevoius post, I shot more lights for this dim planetary in Constellation Lynx, since IC 433 was too low after midnight.
Due the low brightness this objet is not commonly imaged, even though it has a largish angular diameter to a planetary nebula. (6'.67" x 6'.67")
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 @ 9Hz
Image Scale, 1,5 arcseconds/pixel
