Standard planetarium apps have pointing errors of several degrees, putting objects out of view. AstroHelm matches real stars in the sky to pinpoint your exact coordinates with sub-arcminute accuracy.

The best dark-sky sites don't have Internet access. AstroHelm’s plate solving engine runs entirely on device. No internet connection required, and your camera images stay on your phone.

AstroHelm works with equipment you already have, whether it's a dobsonian, a DIY telescope, or a telephoto lens. No lock-in. No proprietary hardware.

Not sure what to observe? Discover rewarding targets for your location and tonight’s sky, taking altitude, twilight, and moonlight into consideration.

Leave one device on your telescope and guide it from another in your hand, so you can explore the sky without reaching for the mounted screen.

Works with astronomy software you already use, including Stellarium and SkySafari. AstroHelm acts as a telescope through ASCOM Alpaca, INDI, or LX200.
