Calcium Closeups 24th March

Using the Skywactcher ED80 stopped down to 60mm to help with both bad seeing and also reducing the effects of spherical aberration, and, along with a 3x barlow and the IMX174 chipped camera to result in a good sampling ratio meant I got some have decent mid scale closeups in calcium light.  While no real main features I just concentrated on the brighter regions that are visible at the moment.
