arcsecond-service-platesolver-astrometry 1.2.4

Arcsecond plate solver based on astrometry.net indexes

Arcsecond Service: Platesolver (astrometry)

This repository provides a FastAPI plate-solving service for Arcsecond, based on astrometry.net indexes and Neuromorphics Systems' astrometry Python package.

Astrometry index files (~10 GB) are baked into the Docker image at build time under /opt/astrometry. No downloads occur at container startup.

Run with Docker

docker run --rm \
  -p 127.0.0.1:8900:8900 \
  arcsecond-service-platesolver-astrometry:latest

Run Natively (Linux/macOS)

python -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install .
python -m arcsecond_service_platesolver.main

Run Natively (Windows)

1. Install Python 3.12+.
2. Install Microsoft C++ Build Tools (Desktop development with C++).
3. Install Rust (rustup), because astrometry may need a local native build when no matching wheel is available.
4. This project pins Windows installs to a Windows-compatible astrometry fork commit from arcsecond-io/astrometry.

py -3.12 -m venv .venv
.venv\Scripts\Activate.ps1
python -m pip install --upgrade pip
python -m pip install .
python -m arcsecond_service_platesolver.main
