The Crab Nebula
No other object in my gallery has required as much time and patience as this one. I spent 10 nights imaging over the course of 13 months.
Two of them a total
failure, one of them yielding only a single subframe and others quite successful. In one night the moon was so close that a bright arc was
cast onto the sensor and all subs needed to be cropped in order to be stackable at all. The seeing was poor quite often, up to 6 arcseconds
in some nights.
