CaK Full Disk 13th April

The sun always looks nice when there's a large active region complete with spots and plage and todays sun fitted the bill.  Taken with the ED60 at f12 this scope has noticeable more spherical aberration at 393nm than my other refractors, but with the Skywatcher AZ Gti mount makes for a very nice grab and go setup.
