My Second attempt at imaging the Crab Nebula was much more successful than the first. This version consists of 20 5-minute subs at ISO-800. I processed the 32 bit TIFF that Deep Sky Stacker autosaved. This seemed to produce the best image. It took several attempts to create this image, but once I discovered the 32 bit processing had a little more control over the beginning steps in the processing, I decided to use it for this image.
"The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. The nebula was observed by John Bevis in 1731; it corresponds to a bright supernova recorded by Arab, Chinese and Japanese astronomers in 1054. At X-ray and gamma-ray energies above 30 keV, the Crab is generally the strongest persistent source in the sky, with measured flux extending to above 1012 eV. Located at a distance of about 6,500 light-years (2 kpc) from Earth, the nebula has a diameter of 11 light years (3.4 pc) and expands at a rate of about 1,500 kilometers per second. It is part of the Perseus Arm of the Milky Way Galaxy."
"At the center of the nebula lies the Crab Pulsar, a neutron star (or spinning ball of neutrons), 28–30 km across, which emits pulses of radiation from gamma rays to radio waves
with a spin rate of 30.2 times per second. The nebula was the first
astronomical object identified with a historical supernova explosion."
I successfully imaged the Crab Nebula pulsar. It is extremely faint, but according to what I've read, this next image points to it...
These images were taken with a 6" Newtonian Reflector and a Canon 300D DSLR.
