A dedicated astrophotography camera designed to vividly capture red nebulae.
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.
Based on the OM SYSTEM OM-3 mirrorless interchangeable-lens camera, this is a dedicated astrophotography camera has been optimized for astrophotography by adjusting the optical characteristics of the infrared cut filter positioned in front of the image sensor, enabling vivid capture of red nebulae that are highly popular among astrophotography enthusiasts. By combining OM SYSTEM’s computational photography features with optional body mount filters and a wide lineup of M.ZUIKO DIGITAL lenses, the OM SYSTEM OM-3 ASTRO enables a broad range of astrophotographic expression—from starry landscape photography to detailed imaging of constellations and nebulae. This model will be available on a made-to-order basis.
Capture Hα rays with TruePic X. The most powerful image processing engine in OM SYSTEM, captures beautiful red nebula in stunning, high-resolution detail.
The OM SYSTEM OM-3 ASTRO features an IR-cut filter positioned in front of the image sensor, with optical characteristics optimally tuned to achieve approximately 100% transmission of Hα wavelengths, which are vital to astrophotography. This allows the camera to vividly capture the beautiful shapes and colors of nebulae emitting Hα light, which are difficult to photograph with standard digital cameras.
In addition, the combination of a high-sensitivity back-illuminated stacked Live MOS sensor, OM SYSTEM’s highest-performance image processing engine TruePic X, and the color profile control functions of the OM SYSTEM OM-3, enables clearer reproduction of star colors and faint nebulae, delivering high-resolution image quality even in high-sensitivity shooting.
The color profile control functions of the OM SYSTEM OM-3 ASTRO allow users to create more impressive expressions in both astrophotography and starry landscape photography. In the custom modes C1 to C3, color profiles are preset, with COLOR1 optimized for astrophotography such as imaging red nebulae, and COLOR2 optimized for starry landscape photography. By combining the custom modes with these color profiles, users can easily capture impressive images of the night sky.
Designed to handle a range of shooting scenarios from starscapes to astrophotography.
Beautifully capture a broad range of celestial objects using a selection of high-quality M.ZUIKO DIGITAL lenses from wide-angle to telephoto, you can choose the perfect lens for your subject. Whether you are shooting spectacular starry skies, homing in on specific constellations, or capturing distant nebulae, this camera is up to the task. And if you are looking to take your astrophotography to the next level, you can even mount the OM SYSTEM OM-3 ASTRO body to an astronomical telescope using a commercially available Micro Four Thirds compatible adapter.
Features that bring the night sky to life
From starlit skies to long exposures, the OM-3 ASTRO unlocks the magic of the night with Starry Sky AF, Night Vision Mode, and Live Composite—powerful features that make capturing stunning low-light images effortless, with no extra gear or guesswork.

Compact and durable. Ready for night sky adventures
The OM-3 ASTRO is built for night sky adventures, with a lightweight, full-metal body under 500 g and IP53-rated durability. From starlit landscapes to remote deep-sky locations, it stands up to the elements so you can focus on capturing the celestial expanse.
-
IP53-certified weather-sealing: Shoot the night sky anywhere, anytime. With IP53-certified protection against dust, rain, and cold, your camera is ready to capture stars, nebulae, and celestial events in any conditions.
-
Compact & lightweight: Weighing under 500g, this camera is perfectly designed for night-sky photography—easy to carry to remote locations and built to capture the stars with precision and clarity.
-
USB power: Keep your OM-3 ASTRO powered through long nights under the stars. With USB-C PD charging, you can connect a power bank and continue shooting without interruption—perfect for extended astrophotography sessions in the field.
Capture the stars like never before with powerful in-camera features
-
Handheld High Res Shot: Shooting with Handheld High Res Shot when the camera is mounted on a tripod will produce composite images in which the diurnal motion of the stars is corrected.
-
Timelapse: Capture the motion of stars and planets, entirely in-camera. Produce smooth night-sky timelapses ready to export in stunning 4K resolution.
-
Color profile control: Create vibrant night skies with preset color modes on the creative dial, designed for astrophotography. Easily apply optimal settings for red nebulae or starry landscapes, adjust saturation, highlights, and shadows, and save your favorite profiles.
Why Handheld High Res on a Tripod?
High Res Shot uses in-camera stacking to produce higher-quality images with greater detail and reduced noise.
By capturing and compositing multiple frames, OM SYSTEM’s High Res Shot function generates ultra-high-resolution images. While Handheld High Res Shot is typically used without support, fixing the camera to a tripod or equatorial mount allows astrophotography-style stacking to be completed in a single in-body process. This approach increases resolution and corrects star movement or tracking errors, resulting in cleaner, sharper images.
Tip: When shooting fixed on a tripod, set the shutter speed so that the exposure time per frame is such that the stars appear as dots.
Remotely capture flawless night-sky shots with perfect stability
Use the OI.Share app or RM-WR2 remote controller to capture stars with pinpoint accuracy. Shoot long exposures, timelapses, and high-resolution astro images without touching the camera, keeping every frame sharp and stable.
-
RM-WR2 Wireless Remote Control Release: Wirelessly control your camera via Bluetooth using the RM-WR2 for precise, stable night-sky photography.
-
The free OI.Share App: Wireless remote control, camera live view on your mobile device screen, and browsing and importing images—even with the camera in your backpack. The OI.Share app does it all.
Color Profile Control
For the final touch, the OM-3 ASTRO’s color profile control enhances night skies straight out of the camera, emphasizing red tones so nebulae and stars stand out with dramatic, expressive impact.
