About this image

This was the largest sunspot on the disc for a while... Was experimenting a narrow-band UV filer (primarily used for CN observations in comets) to see if I could produce a faux Ca image. With a bit of false colour it turned out not too bad. Image constructed from 100 video frames, 640x480 at 50fps to try and freeze the seeing.
