Taken on 21.8.17 from a hill in Idaho USA, on 21.8.17, using a Canon 500D DSLR with a Canon 200mm F2.8 telephoto lens on a fixed tripod. For High Dynamic Range (HDR) photography I used 3 bracketed exposures of 1/128, 1/32, 1/8 sec. at F4. ISO 200 and the RAW images were combined in Photomatix Pro 6 software – Fusion/Natural. The detailed structure of the corona was enhanced with Topaz Clarity then ProDigital AstroFlat Pro Plugin followed by Topaz DeNoise6.
