  • Show HN: An open source astronomy dashboard (HTTPS://caelus.siderealcode.net)

    Hey! I’m using ephemerides from JPL (Development Ephemeris) and IMCCE (INPOP). I also developed an open source library for extracting data from these ephemerides: https://github.com/rhannequin/ruby-ephem

    These files provide geometric barycentric data. So they need quite a bunch of transformations and physical corrections to become accurate coordinates usable by an astronomer. That’s Astronoby.

    And finally Caelus is the project that uses the final data for astronomy use-cases.
