The Crab Nebula
The Crab Nebula (M 1) is one of my favorite objects at this time of year. This remnant of a supernova observed by Chinese astronomers in 1054, is expanding rapidly (1500 km/sec). The inner part of the nebula contains a pulsar that produces high velocity stellar winds which dominate the central part of the nebula. It emits highly energetic gamma rays, and was the first identified astronomical source emitting gamma rays of over 100 TeV.
This image was produced from 1256 x 10s integrations (approx. 3.5 hours). Captured with a Seestar. Initial processing in Siril, with noise reduction in Topaz and tweaking in Affinity and Nebulosity.
