A very active Sun - 24 April 2014
Hi All,
Just sharing some images I composited today. Had to image the Sun after seeing a lot more flares around the solar edge then before.
I Don't know why I'm getting a moire effect on the F30 pictures, I suspect, correct me if I'm wrong, it's the fact that the DMK41 has no low pass-filter before the sensor and at that focal length the difference in focal points on the Solar sphere is enough the have the central part (closest point to the CCD) slightly out of focus, resulting in the effect.
Clear Skies,
Mariusz
