Hey all,
Quite the blank disc lately! But, I woke up to a lovely grouping of prominences on the limb. Weather is terrible, some clouds, and windy. Seeing was pretty bad actually too. Could barely get good surface spicules detail. But the proms came through, and that's what I really wanted. Even though its a solar minimum, there are still lovely things to see in the different wavelengths and hydrogen alpha always provides something to image or see, be it the surface itself and some features, or my favorite which are the mighty prominences.
Imaged with a 120mm F8.3 achromatic refractor and a Quark Chromophere for the Hydrogen Alpha views, and threw in a 0.5x focal reducer (on the camera nose) to change scale & FOV a little during some poor seeing. I tune mine to nearly all the way to the blue side (9 o'clock if I recall). For the white light, I used the same scope, with Baader Solar Film, Baader Solar Continum (540nm) and an Explore Scientific 3x Focal Reducer. ASI174MM is the camera I use for all this.
From my observatory I recently finished:
Setup:
Mount: Orion Sirius (HEQ5)
Imaging OTA: Celestron Omni XLT 120 + Linear Bearing GSO Focuser + 80mm Extension Tubes x 2 (I don't use a diagonal)
HA Filter: Quark Chromosphere
White Light: Baader Solar Film & Baader Solar Continuum (540nm) Filter
ERF: Baader UV/IR Cutter (in the focuser on the nose of my extension tubes)
Focal Extender: Explore Scientific 3x Focal Extender (only for White Light high resolution surface)
Focal Reducer: GSO 0.5x (to control scale & FOV when seeing is poor)
Software: SharpCap (capture), imPPG (decon & histogram stretching), Photoshop (all other edits); Colored in post
I captured 300 frames per sequence.
I stacked 31 images for virtually everything here except the prominences I stacked 41 (to reduce noise and increase S/N ratio for processing latitude).
Seeing was a solid 2 at best moments, 1 most of the time, with lots of low clouds passing through; I had to image through sucker holes.

You had a good run of images there Marty. Sounds like your seeing was the same as mine.

Nice work on the proms. I was trying to capture those guys yesterday too, but couldn't get anywhere near the detail that you have
Looking good
