The OM SYSTEM E-M1 Mark III ASTRO has an IR cut filter in front of the image sensor that has been optimised for optical characteristics to achieve approximately 100% transmittance of Hα rays, which are important for astronomical photography. This allows you to vividly capture the beautiful shapes and colours of nebulae that emit light from Hα rays, which are difficult to capture with ordinary digital cameras.

Combining a wide variety of M.ZUIKO DIGITAL lenses, from wide-angle to telephoto, which can be selected according to the subject, you can capture beautiful images of various celestial objects, from magnificent starry skies to specific constellations and distant nebulae. In addition, using a commercially available Micro Four Thirds compatible adapter, you can attach it to an astronomical telescope and take pictures.

Not only is the OM-1 Mark II built compact enough to go with you anywhere. It also introduces industry-leading features to let you leave needless things behind.
With a record 8.5 EV stops in camera stabilisation, you can ditch the tripod with confidence and travel lighter.

Custom mode includes convenient settings for starry sky photography

The camera is equipped with convenient settings for starry sky photography in the custom modes C1 and C2 (mode dial) to make it easy for those just starting astrophotography. In addition to the initial settings, such as setting AF mode to Starry Sky AF and LV Boost to On2, frequently used functions in the astrophotography workflow are assigned to buttons so that they can be called up quickly. While it is common to finish astrophotography by adjusting the colour tone and other aspects during post-shooting development, the custom modes C1 and C2 also have settings suitable for astrophotography, such as white balance and tone curve, so that natural images can be obtained even when output from the camera.

C1 setting: This mode uses Handheld High Res Shot to capture high-resolution astronomical photographs. Use a tripod or equatorial mount to take photos.

C2 setting: Drive mode is set to Single Shot. Image stabilisation is set to S-IS AUTO to support handheld shooting.

*Each setting can be changed/overwritten to suit the subject and photographer's preferences.

Body mount light pollution cut filter BMF-LPC01
(The body mount filter is included with the E-M1 Mark III ASTRO and sold separately.)

Light pollution filters cut out light from artificial light sources such as city lights and street lamps. This prevents colour casts in the night sky, allowing you to capture the original beauty of nebulae and constellations more vividly. In addition, since the area near the horizon is most susceptible to light pollution, they are also effective when photographing constellations rising in the eastern sky or setting in the western sky.

Body mount soft filter BMF-SE01
(The body mount filter is included with the E-M1 Mark III ASTRO and sold separately.)

The high-resolution M.ZUIKO DIGITAL lens forms a clear point image of stars, which are ideal light sources. On the other hand, because many stars are recorded as point images, representative stars may not look impressive. By using this soft filter, you can achieve the effect of blurring and emphasising point light sources, making brighter stars appear larger and more blurred, and the colours of the stars are also emphasised, making the stars and constellations stand out.

Other useful features

Like the E-M1 Mark III, it is equipped with a variety of functions that are ideal for starry sky photography.

- Starry Sky AF: Focus on the stars

- Live Composite function ideal for shooting star trails

- Digital level for easy leveling even in dark environments

- Convenient for long-term shooting, USB power supply from USB/PD compatible devices
