Astrophotography asset management and automation

What it does

psf-guard watches your astrophotography folders, tags images with metadata, and automatically syncs them to a cloud storage target.

When to use it

•You capture hundreds of FITS/PNG files each night and need a hands‑free way to organize them.
•You want to back up raw astrophotography assets to S3 (or another remote) without writing custom scripts.
•You need automatic renaming and metadata extraction (exposure, ISO, target) for later cataloguing.

Ready-to-paste prompt

psf-guard watch --config ./my-psf-guard.toml --log-level debug

Heads up: psf-guard requires the AWS CLI credentials (`AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`) to be set in the environment for S3 sync; without them the `sync` command will fail.
