Shoot 2022-06-30-195410

This gallery contains some recent landscape and astro shots. For the recent planetary alignment I shot before dawn on June 24, 2022, in a single frame I was able to capture Venus, the Moon, Mars, and Jupiter in a remarkably straight line. In the two-shot panorama I was able to also capture Saturn. I'll make a separate blog post since the planets aren't really visible in the small images here.

While birding, I saw a new lifer: Black-necked Stilt. The lighting wasn't great for photography but I enjoyed watching a couple of these birds walking around.

My "birds in review" collages can be found here.

📄 hashes-2022-06-30-195410.txt.sig

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.
