Description

The sun as of Sunday, 20 September 2020, in narrow band Hydrogen Alpha. This time I also took the flats, to manage the interference phenomenon of the "Newton's rings" and to keep the brightness of the scene uniform. The focus is more curated, and I'm starting to notice some differences in the Daystar tuning settings. The seeing unfortunately didn't help, but I'm still managing to extract some more details.
