AR11818 Closeup 11th August

This active region is crackling with activity, with small loops and ribbons of solar plasma held aloft by magnetic fields. Judging by the jet spicules on the limb there is more activity going to be rounding into view in the coming days. In order to get this shot I upped the focal length to 3200mm using the 100mm PST mod and DMK31 camera. It's just on the limits of the seeing conditions but I reckon this image works!
