Sun in CaII K ND3.8 : first details

Observation of the Sun with Baader Ca II K filter showed some details. I was still practicing and did not expect too much. So this result was far more then I expected. 

Set up : Nikon D7500 and TAL200K f/8.5. Baader Ca II K filter, Solarfilm ND3.8, ISO800 and exposure time of 8s. Editing using CS4.
