The Sun, through filters
While I have a few theories about why the UV, through glass, looks the way it looks, I’ll leave the theory out.
ASI 178MM (cooled), %filter%, TS-Optics 76/342 TS76EDPH, mountpusher, EQ3-mod with either ND5 or ND3.8, as the band pass filter asks for it.
Also, I updated the filterwheel’s firmware. If you are wondering why it’s not on github, wonder about microsoft a bit.
One can see how limb darkening is truly stronger in the blue end of the spectrum, and that for most intents and puproses, the Calcium K yields the second best amount of detail, after the… hydrogen alpha. The solar continuum is, comparatively, useless for full disk images.

Using the MC102/1300 and the TS-Optics 76/342 TS76EDPH, mountpusher, EQ3-mod, with the ASI 178MM (cooled) and ASI 462MC (cooled) with various accessories, barlows and the Baader K-Line Filter 1.25″ (double stacked) for Venus, I obtained the following images. Venus’s featureless disk is artificially generated, to simulate the visual part of the spectrum, represented as orange in the false color, vs the cyan of the CaK.

Using the ASI 178MM (cooled) and ASI 462MC (cooled), with various barlow setups, for Venus the Baader K-Line Filter 1.25″ (double stacked), TS-Optics 76/342 TS76EDPH, mountpusher, EQ3-mod, I observed Venus, Jupiter and Saturn, as best as possible with the rather modest setup and inadequate ersatzobservatory, which isn’t even an observatory, just a good patch of sky and an open window. Still, I got maybe some detail on Venus, Jupiter’s clouds with Io’s shadow and Io, and Saturn with the Cassini gap, give or take. Thank you, real estate maffia, thank you.
