Introducing the OM-3 Astro
Experience creative freedom redefined under open skies. The OM SYSTEM OM-3 ASTRO is a dedicated astrophotography camera designed to push beyond daylight, capturing stars, galaxies, red nebulas, and nightscapes with confidence and precision. From glowing horizons to silent, remote dark skies, it lets you explore the universe and your creativity, wherever the night takes you.
Dedicated power for astrophotography
A dedicated astrophotography camera engineered to capture faint Hα light, from expansive starscapes to deep-sky detail.
Built to capture red nebulae
A dedicated IR cut filter tuned for Hα wavelengths, combined with powerful TruePic™ X processing, reveals vivid red nebulae and fine celestial detail, delivering stunning image quality from wide starscapes to deep-sky scenes.
Astro-tuned colour & custom modes
Preconfigured custom modes and dedicated color profiles make capturing the night sky effortless. From red nebulae to starry landscapes, optimized stacking, Starry Sky AF, and astro-tuned color deliver impressive results—beautifully rendered straight out of the camera.
Deep-sky detail, perfectly aligned
When Handheld High Res Shot is activated with the camera mounted on a tripod or equatorial mount, multiple exposures are combined into a 50MP image. Intelligent image alignment reduces noise and corrects star motion and tracking errors for crisp, high-resolution astrophotography.
