Brierley Hill Solar 21 Feb 16

I was really pleased with all the fine detail that was visible in this filament, it looked unusually dark on the surface of the sun.

Taken with the 100mm Tal100R refractor, Daystar Quark and PST etalon, and the PGR Blackfly GigE IMX249 camera, all running at a focal length of about 3200mm.
