What is AstroHelm?
AstroHelm is a mobile application for iOS and Android that uses on-device plate solving to help users locate celestial objects through a telescope or camera. By mounting a smartphone on the equipment, the app continuously analyzes the night sky to guide the user directly to galaxies, nebulae, planets, and stars.
The software runs entirely offline, matching real stars against a local database to determine pointing coordinates with sub-arcminute accuracy. It works with any existing telescope setup, including Dobsonians and telephoto lenses, without requiring a motorized GoTo mount or proprietary hardware.
Users can browse a curated list of nightly highlights tailored to their location, weather, and moon phase. The app also connects to third-party astronomy software like Stellarium and SkySafari via standard protocols such as ASCOM Alpaca, INDI, and LX200.
