Solar Imaging with poor visibility
12 January 2014
The weather forecast called for clearing skies, but I only have about an hour window where the Sun clears my neighbor's building and where I lose it to trees and stuff. Setting up early, the prospects of some decent imaging was going to be poor. Every once in awhile, I would get a sucker-hole where the Sun sorta pushed through and quickly snapped a pic....
Using the T5i and adapters coupled with the trusty C102 Refractor, I only managed one half-decent solar disk image, but it did capture massive solar sunspot group AR 1944, which recently belched out a good sized CME toward Earth last week....
From top to bottom:
T5i Camera T-Mount Adapter T-Ring to 2" Eyepiece 40mm ScopeTronix Maxview eyepiece 2" Focal Reducer tube (Minus the glass)
For closer pics, I pop in the 2" 2x Barlow
And finally, a Yellow filter screwed onto the Right Diagonal, fitting into the Dual-Speed focuser
I didn't even get an hours worth of semi-clear skies on this session, as the skies were mostly mucked up....
With only about 20 minutes worth of sucker holes, the Chicago skies closed up and this brief chilly session was over.....

Given that the massive sunspot region AR 1944 was at it's best around the time of the blizzard & polar vortex, I skipped trying to observe it on the days with very subzero windchills. When I tried to observe it later in the week, it was just a little too hazy to focus the Sun in my 60mm refractor that I use for projection solar observing. I would have liked to have seen it, but it was on display during a bad stretch for observing around here. Glad you captured it, even if conditions weren't ideal.
