I shot the nearly 1st quarter Moon on May 13th. I'll make a separate blog post with more details, but my goal was to try lucky imaging with some python code I wrote for aligning and stacking frames. I stacked the best 1%, 2%, and 5% of 1,190 frames and the 5% stack (59 frames) looked the best to me. For a "drizzle algorithm" effect I upscaled each image by 3x before alignment — with the goal of revealing more detail captured between individual pixels of each frame. The processing times were very slow but I'm pretty happy with the results.

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.
