Post by arnedanielsen »

Dear friends,

FD images of the Sun in H-Alpha, CaK and Continuum from May 20th 2023. FD H-Alpha with both Coronado SM60 and Coronado SM90 filter mounted on the StellaMira 80mm.

I also recorded some close-up images of the AR's in CaK as well as a H-Alpha timelapse that I will post later.

Click on images to view them in full size on AstroBin.

Superb.


I do not look at the sky with the eyes of an astronomer, but of a person looking for the beauty of nature.
