Solar shots in white light and Ha - 21 April 2022 - 11AM UT

[Roberto]

Hello All

I trust you are all well.  I took some shots of our Sun last Thursday at midday.  There are quite a few active regions on the face of the Sun, particularly in its northern hemisphere which augurs well for the next solar cycle.

Below taken in white light with a 10" Maksutov working at f/25 (6250mm focal length, 0.19"/px).  Best 200 out of 2000 frames for a two panel mosaic of AR2993 and 2994.

Shots in Ha taken with a 94mm f/7 refractor working effectively at f/14.  Best 500 to 1000 frames of 5000/10000 frame videos.

All using a ZWO ASI174MM CMOS camera.
