Here is yet another view of the Crab Nebula, M1, in the constellation of Taurus. It is a beautiful representation of a super nova remnant, with colorful tendrons highlighting strong OIII and Ha emissions. This shot was taken at f/10 and despite 3 hours of total exposure, it really needs another 5 hours or so to match what I normally achieve with 2 hours at f/5! There were no issues with guiding through the use of 2 minute exposures, but some optical issues were still noted in the star shapes. This shot was taken at Chiefland.
