Sun CaII K-line


This afternoon I took some pictures of a quit Sun using Baader filter CaII K-line without my solarfilm ND3.8. Doing this I was able to focus much better which resulted in very sharp pictures.

Setting : Nikon D7500 with TAL200K f/8.5; ISO800 and exposure time of 1/50s. Editing using CS4.
