Solar activity on 9 September 2021

Today we had excellent seeing here in the Netherlands. I imaged the Sun with three scopes in four configurations:

- SkyWatcher Esprit 150ED @ f/7 with ND5.0 filter and ZWO ASI1600MM Pro Cool
- Celestron C11 EdgeHD @f/20 with ND5.0 filter, Baader Continuum filter and ZWO ASI174MM
- Lunt LS80THA single stack @ f/7 and f/28 with ZWO ASi174MM

According to a home-built Solar Scintillation Seeing Monitor, the seeing was about 1.5-2.0" during the white-light recordings and about 4" during those with the Lunt.

The active regions are AR2863, AR2864, AR2866, AR2868 and AR2869. Regions AR2866 and AR2868 are the two in the C11-image.

Agree, 2nd shot is superb, and the others aren't bad 😂.  Great imaging.
