First time shooting at the Moon in a proper way: APS-C sensor paired with the 70-200mm f/4 Sony FE lens. The formula I was given didn’t work for me: 100th f/16 ISO 100; I ended with a better exposure shooting at 1/10th f/22 ISO 100. And I cropped the image to a 10” x 10” @ 300ppi for a result I was happy with, due that surrounding clouds had moved away by the time I got it.
