Equipment Details:

Nikon D500 (DX 1.5x crop factor), Nikkor 300mm f2.8 lens (effective focal length of 450mm); Three-way geared head on tripod with cable release.

Post-processing Details:

Original 2017 totality eclipse HDR image (created using Aurora HDR) modified in Photoshop with an overlay of lines and text to show the relative field-of-view of common effective focal lengths in relation to the size of the corona.

Image Details:

I utilized an HDR image I created using a 9-image bracket series I took during the 2017 Total Solar Eclipse and overlaid frames indicating the relative field-of-view of common focal lengths to help photographers planning to photograph the 2024 eclipse to visualize what focal length is optimum for their imaging goals. I go into much more detail in my "How to Photograph a Solar Eclipse" post on my website, but it is a quick way to visualize the differences.
