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.

Thank you Roger!

A few more taken this morning.  Now with full discs in CaK and White Light using the 94mm refractor at 1500mm EFL.

Thank you Carole!  Lucky the Sun was out and the seeing was above average; typically doesn't happen like that!

We're all guinea pigs in the laboratory of life. Better a fluffy guinea pig than a lab rat!
