M1 as a Stereo pair, New version
Parallel 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.

M1 as an animated 3D-image, New version
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!

M1, an anaglyph 3D, New version
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.

M1, the "Crab Nebula", finalized
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 Crab Nebula supernova remnant locates in constellation Taurus. The actual, bright, supernova was seen by Chinese and Arab astronomers in 1054.
Distance from Earth is about 6500 light years and diameter of the nebula is about 11 light years. Supernova remnant expands at a rate of about 1500 kilometers/second.
Last night I shot S-II channel and, for the first time, broadband luminance to show the broadband component in the nebula. There is a, 30 rounds per second spinning, massive, very magnetic, neutron star in the core of the M 1. The hot plasma strikes existing gas, causing it glow in colors across the electromagnetic spectrum. Without broadband luminance, I can show only a part of the nebulas appearance.
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.
