The Sun on 2022-12-21
On the day of the winter solstice, which is calculated to have occurred at precisely 21:48Z, I imaged the Sun in three narrow bands:
Hα
CaK
SlC 7.5nm

EQ3-mod, mountpusher, Sharpstar 60/330 ED-APO, Lunt CaK B600 LS6CAKMDS2, ASI 178MM (cooled)
EQ3-mod, mountpusher, Baader Astrosolar ND3.8 Film, TS-Optics 76/342 TS76EDPH, Baader Solar Continuum 7.5 nm 1.25″, ASI 178MM (cooled)
Although not used per se other than being in the light train for the S7C (solar continuum 7.5nm version) filter, it was a fun project so let me mention the automated filter wheel for credit.
