myastro

Personal astronomy data toolkit with a ledger: what you already have, how it was fetched, and whether it is still on disk. Python API + CLI + TUI.

What it does

• Fetch from 10 public surveys (TESS, Gaia, ZTF metadata/light curves/frames, Legacy Survey bricks, MPC, SIMBAD, VizieR, unWISE, ASAS-SN when upstream is up).
• Ledger: every dataset is recorded (source, params, files, sha256 baseline) in local SQLite — dedup, retry, audit and coverage all build on it.
• Find your own data: precise cone search, keyword search, coverage against catalogue indexes.
• Audit: hash baseline checks, orphan detection, doctor self-check, ledger backup/restore.
• Extend: third-party sources go through the plugin protocol (plugin API, Chinese).

Install

pip install myastro

Requires Python ≥ 3.11 (macOS/Linux; Windows untested). Optional extras and the aria2 system dependency are covered in Install.

Next steps

• Install — extras, aria2, environment variables
• Quickstart — first fetch, the TUI, searching your archive
