Here is what Michael wrote in the e-mail:
[...] an image that was acquired with a DMK 31AU03.AS (USB version) and a modified 4″ PST at 1m focal length on Mar 19, 2010. Although the videos were taken through an open window and the sun was already quite low at 5pm (12° altitude!), the seeing was quite ok at this focal length. I took 6 videos of the surface and one of the big prominence.
1000 images each, 10-12% were used (AviStack), processing with Fitswork, stitched it together using Gimp. The active region to the left is AR1056, the right one AR1054.
I've got a now, homepage, there are even more images taken with the DMK 31AU03.AS
