Just picked up a CaK module for my LS152 solar telescope and thought I would post some of the results of imaging. The module switches with the hydrogen-alpha module in a few minutes and consists of a herschel wedge to remove most of the infrared/heat, with a trimming filter assembly to pick out the CaK wavelength. The CaK light is pretty tricky to see visually so it is more of a imaging setup.

Anyway here are a couple of shots using the setup using a 2x (1800 mm focal length) and 3x (2700 mm focal length) barlows, plus a hydrogen alpha shot. These were taken on September 8 and 9 using a Skynyx Lumenera 2-1M camera.
