Mini CaK Loops - 20th february

As this active region passed over the limb there was crown of bright plasma coming from it, in particular I like the mini loop that is visible.  Taken with the ED80 stopped down to 60mm with the Beloptik Tri-band ERF, homebrew CaK filter and DMK31 camera running at 1050mm focal length.
