   Astro App▲291

   I really like Stellarium and SkySafari but I felt like these are primarily geared towards exploring the sky but not so much "here are the long list of things I want to see, when can I see them tonight and where". There's also not really a great option I've found that combines sky object planning + location weather details while still being free so I built this. The UI's heavily inspired by NINAs sky atlas + Robinhood. Right now you can: View the altitude chart of objects and 3D view Create lists of objects of interest View the annual max/min daily altitude of an object to find the best…

    Telescope – an open-source web-based log viewer for logs in ClickHouse▲172

    Hey everyone! I’m working on Telescope - an open-source web-based log viewer designed to make working with logs stored in ClickHouse easier and more intuitive. I wasn’t happy with existing log viewers - most of them force a specific log format, are tied to ingestion pipelines, or are just a small part of a larger platform. Others didn’t display logs the way I wanted. So I decided to build my own lightweight, flexible log viewer - one that actually fits my needs.

    Orbit – AR satellite tracker, watch 15k+ objects▲89

    Hey HN! I made Orbit, an iOS app that allows you to see the satellites, planets, and constellations above you in AR, on a 2D map, and on a 3D globe. The app includes more than 15,000 objects tracked by CelesTrack, together with their pass predictions, descriptions, and detailed orbital data. A searchable catalog of all objects is also available, as well as a built-in chatbot designed to answer any space-related questions you might have. This is my first published iOS app, so any feedback is greatly appreciated! App Store: https://apps.apple.com/app/id6772174570
