Sunspot groups AR2108 and AR2109 – July 8, 2014
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.
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…
