2010-11-03 - M1 - The Crab Nebula
The Crab Nebula is the remnant from the supernova observed by Chinese astronomers in the year 1054. At it's center is a neutron star roughly the mass of the sun, but squished down to the size of a city.
29x 30 second exposures shot with a Canon T1i DSLR at ISO1600 on a 190mm F5.3 Skywatcher Maksutov Newtonian telescope. 14.5 minutes total exposure time.
I shot 54x 30 second exposures, and tossed out nearly half of them due to my unsteady LXD75 mount not tracking the stars sufficiently.
It was shot using the camera's long exposure dark frame noise reduction. I need to shoot some flat frames to remove the vignetting.
