I've taken another shot at a composite "HDR" effect moon image. My last attempt from March/April of this year didn't turn out as nicely as I hoped. For this image, I took photos on two separate days: the 99% Moon ("Super Full Moon") on October 17, 2024, and the 27% waxing crescent on November 6, 2024. More details and a larger version are available on my AstroBin page.

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.
This blog post has more details.
