Here is the solar eclipse shot I took yesterday in Idaho. It’s a blend of 7 images so the light close to the edge of the moon is about the same as light further away. Normally light close to the edge is much brighter and will get quickly overexposed. To remedy the problem I took 7 shots starting with 1/1000 going down to about 1/15 of a sec. This allowed me to get longer/larger corona.
There’s some noise in the image, I know. I left it on purpose so that the posterization doesn’t develop when image is compressed and saved for the web.
Shot with my Pentax K-1 and Pentax 150-450mm f/4.0-5.6 WR lens and Pentax 1.7TC so the focal length was 765mm at f/11 and ISO 1000.
