Departing Active Regions CaK Light 8th February

These active regions head towards the limb with a few small proms also visible.  60mm of aperture compared to 40mm seems key in resolving the spicules on the limb.  Conditions weren't great when this image was taken; low sun and high cloud, and so, as a result I look forward to putting this scope through it's paces in ideal conditions.  Taken at 960mm focal length with the homebrew CaK filter and the DMK31 camera.
