M1 has consistently kicked my rear... Maybe until now. I've never been able to get good guiding on this relatively small object. I think I've greatly improved things with my AP 900GTO mount and this image below. See the next image and compare with previous...
Seds notes: The Crab Nebula, Messier 1 (M1, NGC 1952), is the most famous and conspicuous known supernova remnant, the expanding cloud of gas created in the explosion of a star as supernova which was observed in the year 1054 AD. It shines as a nebula of magnitude 8.4 near the southern "horn" of Taurus, the Bull. The exploding star was so bright it was visible during the day for several weeks.
10/2007 image, also from the Davis Mountains. 16x4 = 64 minutes exposures. Canon EOS 20Da (unmodified), ISO 1600, Takahashi TOA 130 (a 5" APO refractor) with flattener, and Astro-Physics AP 900GTO mount. Davis Mountains, TX, 10/2007. I used my Current DSLR Workflow including the Lab technique to accentuate the colors.
The image above is from the 3/2007 Davis Mountains trip and consists about ~25 x 4 min = 100 minutes exposure. This was on a very windy night and the guiding suffered quite a bit because of it. I had to call it quits around 12:30 when gusts in the 15 MPH range kicked up.
Equipment: Canon EOS 20Da (unmodified), ISO 800, Takahashi TOA 130 (a 5" APO refractor) with flattener. Losmandy G-11 mount. My current image processing workflow is here.
