Congratulations for getting these great photos! I have always wanted to catch sprites but so far no luck. Do you have any idea what the distance was to those clouds where the sprites originated? I've always thought that sprites originate from big thunderstorms and you have to be 40 or 50 miles away to see the cloud tops, but those in your photos seem to be much closer.
Thanks! I don't recall exactly, the storm was probably about 100 miles away. Best advice I can give is just keep trying whenever you can see distant lightning flashes and also can see stars in the area. Or just try if you can see stars where you know there is lightning in the direction. The faster the lens the better, I am using a f/1.2 50mm.
Sprites were a bucket list item of mine and I finally caught my first in 2016 after many hundreds of frames captured over many storms.
The set in this thread are the first ones that I actually saw a sprite before attempting to image them. Normally I point toward distant lightning flashes.
