Narrowband

Crab nebula and central pulsar

This is my shot of M1 SNR [Crab Supernova Remnant].   Although not the best opportunity last night under a nearby full moon it records well with the red hydrogen filaments together with the central mag 16.5 pulsar PSR B0531+21 as marked. 

Used my 30cm f/3.3 SCT and SX Lodestar OSC camera - data on image 

Crab supernova was observed by Chinese astronomers in 1054AD as a brilliant new star and even visible in daylight.
 
It contains a neutron star 20km diameter spinning @ 30 times per second emitting a pulsar 'beam' every 33 milliseconds.  This flickering beam has been recorded by a Forum member [not me!] using a rotating shutter before the camera!
