Messier number one - the Crab Nebula wide field

 a while back on one of the groups I belong to, I talked about the possibility of imaging M1 with a short focal lngth. Well, it came to
pass this winter, and is quite interesting in its loneliness... there aren't many other dso's in the field, at least none that
I could find visually. This is almost full APS frame, cropped only for stacking error due to a little flex. Just for fun,
I have included a 200% blow up of the area around the nebula, soft, but interesting with lots of colorful stars... hope you enjoy...

some comments 

The sky was really quite good for this, and I finally quieted my mirror drift, at least on this series.. I am pleased with the star size and shape, and with the performance of the little Mak-Newt.

I think with care, and some lucky skies, one can make interesting images of tiny objects with the wide field camera.
