I have finally decided to get the C11 (280mm) SCT outside for a short solar astrophotography session. It was a good choice. The view of the current Earth-facing sunspot groups was fantastic despite of very few good seeing moments.
The equipment for the following images: C11 at F/10 and F/20 with full aperture AstroSolar filter, ASI120MM with Baader Green CCD filter. Seeing 4-5/10.
A wide-field image of the two groups:
And close-ups of each of the groups.
AR2108:
AR2109:
The main spots of each group were very interesting with lots of inner details and fine structures visible, despite the rather poor seeing conditions.
Hopefully I will have another chance of getting better images of this sunspot groups the next days…
