The "white light" images are actually taken with the H-alpha filters, but cooled to ambient temperature instead of the normal working temperature at 59C

Telescope: AP Starfire EDT 155 mm f/9.
stopped to 50 mm for disc images, with 4X telecentric lens (f/36) for closeups
filter: Solar Spectrum SO1.5/0.3A with CERF prefilter
Camera: Imperx 4M15
North is up, and east to the left.
