M1 - The Crab Nebula - 170130
The Crab Nebula (M1 or NGC 1952) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. The nebula is the remnant of a bright supernova recorded by Chinese astronomers in 1054 A.D. that was visible during the daytime. The nebula lies in the Perseus Arm of the Milky Way galaxy, at a distance of about 6,500 light years from Earth. It has a diameter of 11 light years, corresponding to an apparent diameter of about 7 arcminutes as seen from Earth, and is expanding at a rate of about 1,500 kilometers per second (930 mi/s), or 0.5% of the speed of light. At an apparent magnitude of 8.4, it is not visible to the naked eye but can be detected with a good telescope under reasonably dark skies.
This image was cropped from a test image taken using my new QHY247C camera that I'm beta testing. This is the average of nine ten-minute frames, stacked in DSS and processed in Photoshop. The camera was attached to my Celestron Deluxe CPC Edge HD.
This has always been a challenging target and previous attempts to obtain something I was happy with always failed. While this consists of fewer frames than I might like, the result was good enough that it's worth posting a fully processed image, especially given I might not get much more time on this target this year.
