Description

Newton 380 F / 3.5 ; Filter Ha-12nm 24 frames per 300sec, OIII-12nm, 30 frames per 300sec on QHY163M and color on ASI294 short, four-second exposures, around 4 hours, a total of 8.5 hours.
Became the first astronomical object identified with the historical supernova explosion recorded by Chinese and Arab astronomers in 1054. Located at a distance of about 6,500 light-years (2 PDAs) from the Earth, the nebula has a diameter of 11 light-years (3.4 PCs) and expands at a speed of about 1,500 kilometers per second.
In the center of the nebula is pulsar "Crab Pulsar" (neutron star), 28-30 km in diameter, which emits pulses of radiation from gamma rays to radio waves. In the x-ray and gamma-ray emission range of more than 30 Kev, this pulsar is the strongest constant source of such radiation in our galaxy.It became the first astronomical object identified with the historical supernova explosion recorded by Chinese and Arab astronomers in 1054.
