The Sun.... again

Taken on 19.11.11. The day was drawing to an end and the Sun was setting behind the trees at the edge of the field. The photograph was taken through them as can be seen from the shading to the lower right. This is the first time Lesley Hardware and Elaine Booker had photographed the Sun; they used the IS DMK camera in the PST mounted on the 900GTO mount, a very convenient arrangement. There was a lot of fiddling with the difficult PST focusing(instructions from them to Paul Booker operating the tiny focus knob), and camera settings, to try to get a good balance with both the prominences, and face detail. Not easy with such a wide difference in brightness. They were also hurrying to get the job done before the trees took over completely. The focal length of the PST precludes getting the whole disc onto the chip, but it may be better in summer. The processing was done in Registax 6 and finished off in Photo Shop CS2.
