AstroPup Horizon

AstroPup Horizon allows rapid and accurate capture of your local horizon, using your iPhone or iPad's on-device Neural Engine. No need to capture individual points, just capture a panorama and let machine learning determine figure it out. Magnetometer calibration gets a boost if you include the sun in your image; we'll improve calibration with astrophysics. If needed, make surgical edits or repaint the horizon line within the app. After capture, you can export the data astronomy software such as N.I.N.A., Stellarium, Cartes du Ciel, and SkySafari, and our own AstroPup Sky.
