This is another image shot with the Oshiro 135mm f/2.8 lens (wide open) and an ASI183C.

I have been struggling with the processing on this one, i.e., either I have M8 and M20 the way I want them or I have the background as I want it.

I may do yet another reprocess on this from scratch using a 2x drizzle since Michel gave me a great tip on speeding up PI.

Comments and criticism encouraged!
