Planetary Nebula in Constellation Lynx
Red=S-II, Green=H-alpha and Blue=O-III
Finally, after a long period of bad weather, I was able to shoot more H-a, O-III and S-II channels.
Seeing was not too bad but the transparency was very poor. This is an object with a very low surface brightness and bad transparency eated out some signal.
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

Exposures:
H-alpha 14x1200s, binned 2x2 and 7x1200s, binned 3x3
O-III 2x600s, binned 4x4 and 1x1200s, binned 4x4
S-II 3x600s, binned 4x4 and 1x1200s, binned 4x4

An Universe Today article, Stereo "Soul"
An Article by Tammy Plotner.
At this time Universe today published an article based on my volumized closeup visualization of a "Soul nebula".

Astro photographing in Finland
This it is...
Lots of snow and clouds in winter 2010.
I bet, if I'll start to shoot snow and clouds, we dont see them anymore.

3D-models from 2D-astro images, more testing
In this blog, there is lots of experimental material. To see my actual astroimages, please, see my Portfolio: http://astroanarchy.zenfolio.com/
Links to the original images are with animated models, there is links to other 3D-formats as well.
Animations are made by creating artificial parallax to an image. Then two images are animated together by using a very clever webservice. There can be some artifacts in images, due the experimental nature of this work! The volumetric models are based on some known facts and an artistic impression.
Please, let the images load for few seconds to see them animated!

This has been a very poor winter for astro imaging, playing with old data is one way to try avoid frustration.
We have just two and half months imaging season left up here in 65N. After that no astronomical darkness here until late in the next Autumn : (
