Turn Any Manual Telescope Into
Precision Push-To Telescope
Mount your iPhone on a telescope or camera. AstroHelm continuously plate-solves the sky and guides you directly to galaxies, nebulae, planets, and stars without a GoTo mount or proprietary hardware.
Live Plate Solving
Observatory-Grade Precision in Your Pocket
Traditional astronomy apps rely on your phone's compass and gyroscope, which drifts and lags. AstroHelm takes a picture of the night sky and match it to a massive database of stars, so it always knows where you are pointing.
- Accurate up to within 10 arcseconds (1/360 of a degree)
- Computes coordinates in less than a second
- Immune to magnetic field interference
- Works even in cities with light pollution
Features
Everything you need under the stars
From casual stargazers to serious astrophotographers.
Precision Navigation
Forget the frustrating lag and inaccuracy of standard planetarium apps. Astro Helm uses live, on-device plate solving—matching real stars in the sky to pinpoint your exact coordinates—giving you flawless "Push-To" accuracy.
True Offline Capability
The best dark-sky sites don't have cell service. Astro Helm’s entire plate-solving engine and deep-sky database live directly on your phone. Deep in the mountains or out in the desert, it just works.
Hardware Agnostic
We don't lock you into an expensive, proprietary hardware ecosystem. AstroHelm works with equipment you already have, whether it's a dobsonian, or a telephoto lens.

How to Find Objects with a Dobsonian Telescope Using AstroHelm
Finding faint galaxies, nebulae, and star clusters with a manual Dobsonian can be challenging. AstroHelm uses your phone’s camera to guide you to the target, without expensive motors, encoders, or permanent telescope modifications.
Red Night Vision Mode: The Science and Limitations
Your eyes take 20–30 minutes to reach full dark adaptation. White screen light destroys it in seconds. Here's the physiology behind our red-tint UI mode and how to use it.
