Lunt CaK

Using the EQ3-mod, mountpusher, Baader Astrosolar ND3.8 Film, TS-Optics 76/342 TS76EDPH, automated filter wheel, ASI 178MM (cooled) setup, I imaged the Sun and obtained the following images. See also the The Sun on 2022-12-18 in Solar Continuum, first light article, today’s update.

Also, the heavy artillery Calcium did its job. The lack of high frequency details is due to having 5×4’33 smearing precisely those details away, favoring the large scale structures. EQ3-mod, mountpusher, Sharpstar 60/330 ED-APO, Lunt CaK B600 LS6CAKMDS2, ASI 178MM (cooled)
