Tonight again used my 6 inch F3.6 Cometracker meade Schmidt Newtonian. I shot the Horsehead Nebula, it was tracking very well on the Sampson mount, so went for full 10 minute shots. Final result is:
4 x 10 min shots for a total 40 minute imaging time with my Modded 350D and Baader UHCS filter

Processed with Iris and Photoshop. I used a single dark taken a few nights ago of similar length.
This is the deepest Horsehead shots ive taken thus far.
The odd bluish object top right is an internal reflection. )Corrector plate is not antireflection coated. The Cometracker is a cheaply made scope with a plate glass mirror but does the job
