IC 443 reprocessed, better Blue channel, O-III
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
I reprocessed this closeup of the Supernova remnant, IC 443.

Abell 21, the "Medusa nebula" as an animated 3D
In this blog, there is lots of experimental material. To see my actual astroimages, please, see my Portfolio: http://astroanarchy.zenfolio.com/
Animations are made by creating artificial parallax to an image. Then two images are animated together by using conversion web service, Start3D. 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!

Abell 21, the "Medusa nebula as a Stereo pair.
Parallel vision
Cross vision
NOTE! This is a personal vision about forms and shapes, based on some known facts and artistic impression. Viewing instructions can be found from a Right hand side menu.

Much more stereo images can be found HERE
This stereo pair is a kind of "preview", since I have just started this project. I'll do the final version, when ever project is finalized.

Abell 21, Sh2-274, the "Medusa Nebula", Start of the new project.
Ones again, this target is very low for me, at highest elevation in South, it was about 35 degrees and after a three hours, the altitude was only a 25 degrees.
I managed to get only one 20min frame of O-III, binned 3x3, but there was some signal, so I was able to make the "preview" image as a color one. (Red=H-a, Green=O-III and Blue=80%O-III + 20%H-a)
I'll continue with this target as soon as the weather cooperates againg.
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Levels, curves and color combine in PS CS3.
