AR2786 | HA, CaK | Discs | Dec 1rst 2020
Heya,
Chilly morning today in Florida, windy too, in the 30's F which is really cold for us. Seeing was decent. Transparency was good. But the wind was rather rough. AR2786 still has a gorgeous big spot and lots of wonderful mottling, fibrils and filaments around its area.
B&W:
Colored:
Seeing Conditions:
Equipment:
120mm F10 refractor
Baader Red CCD-IR Block (internal D-ERF) + PST Etalon + 10mm BF + ASI290MM
Baader Blue CCD-IR Block (internal D-ERF) + Lunt B1200 CaK + ASI290MM
ST80 + SM60/Lunt CaK/Baader Continuum + IMX183 for discs
Very best,

A very good set of images indeed Marty. You would have got away with the 8" for Ha first thing looking at the seeing chart. Long may your good seeing prevail!

I was thinking of attempting to use the 8" early setup, but that seeing measurement is only 30 minutes long or so. My seeing went from 0.8" to 1.8~2" in just 30 minutes, sustained. I wish I had a mount capable of holding both my 8" and my 6" frac so that I wouldn't have to swap out scopes, losing some time of my only moments of good sub-arc seeing which lasts minutes in the morning. I have more time in the summer, but in the winter it's a much shorter window. But a new mount just to gain that convenience and bit of time would be over $3k USD, closer to $4k ultimately (CEM60, CGX-L, HDX-110/EQ8) after mounting and counter weights. Sigh! When I think I want to attempt CaK, I leave the SCT off too, simply because it's rotten in near UV anyways, refractors are the best multi-purpose scopes for this after all.
Very best,
