AstroHelm
A software tool that uses a smartphone camera to assist in precisely aiming a telescope or telephoto lens at celestial objects. It employs star-chart matching technology to identify the current pointing direction of the lens and guides users toward target celestial objects, designed as a low-cost alternative to dedicated motorized star-finding systems.

AstroHelm is a project that uses a smartphone camera to assist in pointing a telescope or telephoto lens at a target celestial body.
AstroHelm recently appeared on Hacker News in the form of a Show HN post.
AstroHelm uses plate solving or star matching technology to determine where the lens is pointing and guide the user to align it with the target.
Solutions that rely on a smartphone's inertial sensors (accelerometer, gyroscope, magnetometer) are affected by geomagnetic interference, sensor drift, and hardware differences across phone models, which impacts calibration stability.
Compared to motorized star-finding systems costing hundreds to thousands of dollars, the combination of software and a smartphone is nearly zero-cost, lowering the barrier for entry-level astronomy enthusiasts.
AstroHelm is still in an early demonstration stage, and its actual performance, accuracy, and applicable scenarios await verification through testing by more users.
