I've got an initial version of my April 8th total solar eclipse images here. I wrote some python code to align and stack a few exposures of the totality, to reduce noise. I'll make a separate blog post with full-size eclipse images and more processing details.
More recently, I was finally able to photograph a target owl! It was a Western Screech-Owl. My fourth visit to this location finally paid off: I went just before sunset, in the rain, and set up my camera on a tripod there. I experimented with shutter speeds and found that 1/2 second exposures around ISO 2000 worked fine. I also found that using a remote trigger (intervalometer) and turning off image stabilization on the lens were necessary for sharp images at 1/2 second. I was ready and took a few shots at intervals when it finally took a peek out of the nest hole right around sunset. I was really surprised at how still the owl was sitting — the photos were pretty sharp with 1/2 second exposures.
After taking a look around for a few minutes, the owl disappeared back down into its hole. Since it didn't fly off to hunt, and it was starting to get really dark, I called it a night at that point.

The above hashes-<date>.txt
file contains SHA-256 hashes of all the photos
from this shoot. The hashes-<date>.txt.sig
is a signature of that hashes
file, created with my PGP key. The signature file
itself was written to both the Bitcoin Cash and Algorand blockchains, in the
OP RETURN
and Note
fields respectively, using the transactions below.
In short, this proves that these photos and the signature both existed at the time the
transactions were written to the Bitcoin Cash and Algorand blockchains.
