The Washington Post article Elusive red sprites, like glowing jellyfish in the night sky, photographed in Oklahoma lead me to this tweet and image:

Multiple column sprites line up above an angel sprite in my last sprite lightning capture from the night of 4/17/2019 . An uncropped image on the 50mm about 20 minutes before being clouded over. Anadarko, Oklahoma.

The photographer Paul Smith also has a website: https://www.spritechaser.com/

Question: I'm wondering if the challenge is only in knowing where and when to point, or if there are specific equipment requirements or other technological issues that need to be addressed in order to photograph sprites.
