Re: [APML] Alnitak and the flame nebula

Mike, I don't use the mirror clips in my R200SS, and I should mask out the outer
1/8" to clean up the diffraction patterns of bright stars.

here is a shot of the HH, without the clips and without the mask:

here is another shot, no clips but I used an edge mask on the mirror:

the one with the mask looks a bit better around alnitak.
