Description

Plan to go back for more subs on this - but decided to go ahead and process what I had. This is not a great 104 but much better than my last effort. 
Am working on the focus routine in NINA - both the NINA stock version and the Hocus Focus plugin. Improving. Do find that I have to add fairly frequent autofocus runs into my sequence to keep the focus tight. I may have some primary mirror flop issues. This was taken with a 2" UV/IR filter.
Guiding is starting to get better. Tweeked my PA and made some adjustments to PHD2 and the guiding for this session was close .5 - .6 most of the time. It has taken the better part of a year to move guiding from around .8-.9" RMS down to .5-.6" RMS - but I can see a difference in the stars and the quality of the subs. 
Comments and criticisms welcome!
