As I’m testing out the new observatory, I could test some solar imaging today. Between the clouds!
Setup was a Baader ND 5 objective filter, the Maksutov 180mm F15, ASI174, no additional filters used.
The solar filter as purchased with Astromann at ATT Essen yesterday.
The all sky camera could detect a faint reddish aurora last night, it lasted maybe half an hour.
Look for the reddish, moving waves at the top of the image.
