M1 - Crab Nebula (Narrowband, FLT132)
In 1054, Chinese astronomers took notice of a “guest star” that was, for nearly a month, visible in the daytime sky. The “guest star” they observed was actually a supernova explosion, which gave rise to the Crab Nebula, a six-light-year-wide remnant of this event. It is located 6,500 light-years from Earth in the constellation Taurus, the Crab Nebula can be spotted with a small telescope and is best observed in January.
The orange filaments are the tattered remains of the star and consist mostly of hydrogen. The blue in the filaments in the outer part of the nebula represents neutral oxygen. Green is singly ionized sulfur, and red indicates doubly ionized oxygen. These elements were expelled during the supernova explosion.
This is the first image I have captured with my new William Optics FLT 132 I got for Christmas. The weather has been terrible, so I only managed to take it outside a couple of nights this week. M1 is the first of two targets I managed to acquire with this telescope after some trial and error attempting to balance this (very large) telescope on the AM5 mount and TC40 carbon fibre tripod.
I managed to get just over 7 hours integration time over two days. I used my ZWO ASI2600MC pro colour camera, a quad band and a dual band filters.
