CaK Full Disk 19th October

The seeing conditions weren't great when I imaged my full disk in Ha, but the passing of a weather front meant the air was very transparent and so I had some hope for calcium imaging.  I used the ED80 stopped down to 60mm along with the homebrew CaK filter.  Looking at the enlarged image it is possible to see the spicule ring around the edge of the sun, along with faint prominences.  Looking at the centre of the disk it is possible to see the inverse granulation that characterises the view in Calcium light.
