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.
