Crab Nebula (M1) in HSOrgb


Long integration capture using narrow band filters and HSO palette plus rgb stars.

My longest integration up to now (51 hours), capturing frames during the last three months.


"The Crab Nebula is a supernova remnant in the constellation of Taurus.

The nebula lies in the Perseus Arm of the Milky Way galaxy, at a distance of about 2.0 kiloparsecs (6,500 ly) from Earth. It has a diameter of 3.4 parsecs (11 ly) and is expanding at a rate of about 1,500 kilometres per second or 0.5% of the speed of light."
