Solar Imaging on a Fall Weekend
25th & 26th of October 2014
Using the Canon T5i T-Mounted to the Zhumell variable zoom 1.25' eyepiece and tube extender, it provides a tight versatile set-up...
For Sunday's session I used the same camera, but utilized the 2" Scopetronix variable focal length eyepiece that screws directly onto the T-mount.
This was a great clear weekend in the Chicago area. Crisp fall temps and bright sunshine....and with Behemoth Sunspot AR 2129 Earthside, not an opportunity to miss.
On Saturday, I used the C5 SCT on the GC-5 mount with full aperture Baader solar filter, capturing the sunspot nicely..
At over 80,000 mile in size...enough room for about 7 Earths side by side. Even with just solar eclipse glasses, the Sunspot was easily observable.
Incredible solar event...!
Sunday proved to allow more time with the Sun and I set-up the C102mm Refractor with the same solar filter...
Sunspots 2194 and 2195 were insignificant in white light, but proved to display a very long filament in H-Alpha.
After the imaging, I spent a good 45 minutes staring at the face of the Sun with the binoviewers. Using two 25mm 1.25" eyepieces and various exotics filters, such as O-III and Narrow/Broad band filters, the slightly shifted views were nice and revealing. The pics do not translate on the views through these - intricate magnetic streamers that I swear articulate and subtle umbral shifts.
Two eyes wide open - bring it....
A very satisfactory and productive imaging session and we say goodby to AR 2129. Glad I had the means to stare at you.... monster Sunspot.

Nice pics, Joe.
I know you're a fan of full, big aperture solar filters, but how do you like that PST? The aperture is rather small, but for an H-alpha telescope, the price is reasonable, and from my experience, the views are incredible. I don't have the budget for a PST right now, but I really want to make one my next telescope purchase, whenever that may be.
