Quick Overview Optimized for Astrophotography IR-Cut Filter Passes H-Alpha Wavelength High Res Shot for In-Camera Stacking Custom Modes for Astro/Starry Landscape Starry Sky AF & Live Composite Mode 20MP Stacked BSI Live MOS MFT Sensor 3.0" 1.62m-Dot Swivel Touchscreen LCD 2.36m-Dot OLED Electronic Viewfinder 5-Axis In-Body Image Stabilization IP53 Weather-Sealed & Freezeproof Design Product Description Designed for Astrophotography Excellence Built specifically for night sky imaging, the OM SYSTEM OM-3 ASTRO is a dedicated Micro Four Thirds mirrorless camera fine-tuned for capturing red nebulae, constellations, and other celestial wonders with unmatched precision and clarity. Capture Hydrogen-Alpha Wavelengths At the heart of the OM-3 ASTRO is a specialized IR-cut filter positioned in front of the sensor, allowing 100% transmission of Hα (hydrogen-alpha) wavelengths. Combined with the TruePic X image processor, this adjustment ensures accurate color, detail, and shape reproduction of diffuse nebulae and other deep-sky objects. Advanced Image Stacking and High-Resolution Mode The High Res Shot Mode uses computational stacking to combine multiple sequential frames into a single ultra-detailed image. The Handheld High Res Shot Mode—recommended even when using a tripod or equatorial mount—composites 12 frames into a 50MP photo, minimizing noise and blur while maximizing fine detail. This mode also compensates for diurnal star movement, misalignment, or minor tracking errors when shooting from a tripod or equatorial mount. Astro-Tuned Custom Modes and Color Profiles Predefined COLOR1 and COLOR2 settings simplify astrophotography setup: COLOR1 – Optimized for nebula and deep-sky imaging. COLOR2 – Tailored for starry landscape shots. Custom modes (C1, C2, C3) are preset for specific astrophotography workflows: C1: Frame stacking for deep-sky photos. C2: Frame stacking for starry landscapes. C3: Handheld shooting for starry landscapes. Additional astrophotography-focused features include Starry Sky AF, Live Composite, digital level, Night View mode, and USB power delivery for long sessions. Optional Astrophotography Filters Enhance results further with optional body-mounted filters compatible with all lenses, including fisheye and ultra-wide options: BMF-LPC01 Light Suppression Filter: Cuts stray artificial light for clearer night skies. BMF-SE01 Soft Filter: Slightly diffuses star points to enhance their prominence in the frame. Based on the Flagship OM-3 Design The OM-3 ASTRO inherits its robust foundation from the OM-3, featuring a 20MP Stacked BSI Live MOS sensor, TruePic X processor, and 1053 cross-type AF points for precision and speed—making it powerful for both stills and video. Classic Aesthetics, Modern Control Blending timeless design with innovative control, the OM-3 ASTRO features customizable dials, a creative mode selector, and a computational photography button for instant access to features like Live ND, GND simulation, and focus stacking—perfect for creative astrophotography and macro exploration. 5-Axis Image Stabilization OM SYSTEM’s renowned 5-axis stabilization delivers up to 6.5 stops of compensation (or up to 7.5 stops with Sync IS) to ensure crisp, blur-free images—even during long exposures or handheld night shooting. Video Performance The OM-3 ASTRO also excels in motion capture with: 4K60p video recording Extended recording time with advanced heat management OM-Cinema profiles for cinematic color S&Q mode supporting 1–120 fps for slow or quick motion shooting Additional Highlights IP53-rated splash and dust resistance AI Detection AF for people, pets, birds, and motorsports High-speed burst up to 120 fps (50 fps with AF tracking) Pro Capture Mode stores up to 70 frames before full shutter press Custom labels and mode configurations for personalized control The OM SYSTEM OM-3 ASTRO is a precision tool crafted for astrophotographers who demand the perfect balance of scientific accuracy, creative flexibility, and reliable performance under the stars.
