A black Sun on 2023-01-06, in CaK
In order to obtain my hallmark blue-violet-ish Sun, with the active regions as white, I obtain the brighter-than-average information, long story short, this picture below. While this is usually nothing more than the saturation layer negative I use, now I publish it, cause why not, it looks awesome. Actually, I’ve seen quite many „black suns” that were negatives, curved in weird ways, especially for hydrogen alpha, a sloppy way to deal with the prominences that are much fainter than the bright limb. The Sun below is neither. It is >>the Sun<< in normal light, minus the boring part, which I also posted, for reference.

Sunshine with a Plane, 2023-01-06
Coincidentally this was the first light of my soapbox guider’s newest version, which automatically applies predefined instrument image transformations, to make sure the buttons move the celestial object’s camera image as intended, left is left, without cognitive load, regardless of the zenith flipping, zenith mirror etc. EQ3-mod, mountpusher, Lunt LS60T Ha B600, ASI 178MM (cooled)

The Moon in duoband
From 2022-12-27, I got this picture using the EQ3-mod, mountpusher, TS-Optics 76/342 TS76EDPH, ZWO DuoBand 1.25″, ASI 178MM (cooled).
The Sun in CaK, being photobombed on 2022-12-29
I just wanted to combine the 6x 4’33” stack I obtained with the plane. Which is one single frame, from a video I decided to not use for the difficulty (more like compute time) of getting rid of the tainted frames. EQ3-mod, mountpusher, Sharpstar 60/330 ED-APO, Lunt CaK B600 LS6CAKMDS2, ASI 178MM (cooled). Just like the background, the contrail needed to be extrapolated a bit, for framing reasons. A bit of an artistic license, I guess.
The Sun in UV, 2022-12-28
I recorded the Sun in UV using the automated filter wheel and the EQ3-mod, mountpusher, Baader Astrosolar ND3.8 Film, TS-Optics 76/342 TS76EDPH, Baader Venus U filter 1.25″, ASI 178MM (cooled) setup. The false color picture below was obtained from 6x 4’33 exposure, almost 500GB raw data, give or take. Active regions (brighter than their context) have been emphasized. For reference, I included the registax-output too, which is a the stage before applying the content aware emphasizing and the false color.
