Astrophoto: Sun – 01/17/2023

I knew that the sun had a lot of sunspots these days. Luckily I had the time when the weather allowed a quick lucky imaging session on January the 17th 2023.

It is already some time ago since my last photo of the sun. So I thought I could use the situation and shoot one with a lot of sunspots using my Lacerta Herschel Prism and a Baader Solar Continuum (540nm) filter.
