M 1 – Tau
Messier 1 (NGC 1952) is perhaps the most famous supernova remnant, after the supernova of 1054 in Taurus. It was first observed by John Bevis in 1731. Its distance is estimated in 6500 light years and the gas envelope is expanding at 1500 km/s. Its nickname is “Crab nebula”.
Here, it was imaged with the Planewave 17 unit, part of the Virtual Telescope Project. A total of 36 exposures, with 5 minutes of integration each, were averaged. Images were unguided, completely trusting the Paramount ME mount. The CCD camera is a SBIG STL-6303E. The image scale is of 0.78 “/pixel. Image by Gianluca Masi.
