I was in Jackson, Wyoming for the eclipse on 21/8/17.  

I used a Canon 750d with a 300mm lens. The ISO is 1600, f16 and exp. 1/2000. 

ISO 1600, f16, exp. 1/1600

ISO 1600, f16, exp. 1/1250

ISO 1600, f16, exp. 1/160

ISO 1600, f16, exp. 1/10. All these so far are straight from the camera, no processing.

This is a mosaic of images processed in Photoshop by Nik Szymanek.
