AstroHelm

Find galaxies, nebulae, star clusters, and planets without struggling with star hopping.
AstroHelm turns your iPhone into a smart push-to finder for almost any manual telescope. Using fast, on-device plate solving, AstroHelm recognizes the stars in your camera view, determines exactly where your telescope is pointing, and guides you to your target.
No proprietary telescope. No motorized GoTo mount. Just attach your iPhone with a rigid phone mount and start exploring.

NOT SURE WHAT TO OBSERVE?
AstroHelm can help with that too. Best Tonight highlights bright, interesting objects visible from your location, so you can spend less time planning and more time observing.

HOW IT WORKS
Mount: Attach your iPhone securely to your telescope tube, or to your camera using a standard bracket or hot-shoe mount.
Choose: Pick a galaxy, nebula, star cluster, planet, or other target from AstroHelm's catalog.
Point: Move your telescope while following the on-screen guidance. AstroHelm repeatedly plate-solves the sky and shows you exactly how to reach your target.
CENTER: When the reticle reaches the target, look through the eyepiece—or start your exposure.

BUILT FOR THE GEAR YOU ALREADY OWN
AstroHelm works with manual telescopes and cameras without requiring a specific telescope brand or proprietary accessory. It can also integrate with compatible astronomy software and equipment using standard telescope-control protocols.
Whether you're exploring the sky with a Dobsonian or framing a deep-sky object with a camera, AstroHelm gets you from “I want to see that” to “there it is.”
