I've been obsessed with solar eclipses since I was a kid. I've made a lo-fi rig by cutting up one of those Mylar solar eclipse glasses and taping it to the front of my telephoto SLR lens. It takes some test shots to get the exposure right, but once you do you can get a good shot of the solar disc being covered. Then I take a shot every few minutes and stitch it together in post. This is the effect you get.

I still haven't been in the path of totality and seen the corona yet. One day, one day…
