Hey all, I recently moved house and needed to create new Horizon (.hrz) files for NINA and Stellarium. Instead of going through the normal trial and error I prompted a pretty nifty tool - it runs on https://neuronburner.com/hrz-creator/
It runs completely offline with no tracking etc, this is so you can save the page and run it from disk anywhere you happen to be imaging from.
Enjoy!
