OM System OM-3 Astro

The OM System OM-3 Astro is positioned as a precision tool designed specifically to capture light from the cosmos that conventional cameras ignore. Its most disruptive feature is the hardware modification to its IR cut filter, optimized to allow 100% transmission of the alpha hydrogen line (H$\alpha$). This allows the reddish tones of the emission nebulae to be recorded with deep clarity and saturation, a technical detail that would normally require modifying the sensor externally, losing the warranty and sealing of the body.

For the technical photographer, this camera integrates computational functions that simplify traditionally complex processes. Its in-camera Stackingsystem stands out, capable of combining up to 12 shots to generate 50 MP files with drastically reduced digital noise, automatically compensating for the movement of the stars. Additionally, the introduction of the Body Mount Filters allows light pollution suppression to be applied even on ultra-wide-angle lenses that do not support front filters, maintaining the integrity of the system thanks to its IP53sealing certification.

In terms of its uses, it is the definitive choice for landscape and deep sky astrophotography, allowing you to capture the Milky Way and stellar objects with a professional level of detail without always depending on heavy equatorial mounts. It is also ideal for photography expeditions in extreme conditions, such as capturing the northern lights in sub-zero climates. However, due to its extreme sensitivity to red, it is a niche tool: while in the stars it is unbeatable, in social or portrait photography skin tones would require extensive color correction, so its natural habitat is, without a doubt, the darkness of the night.

  • Stellar Autofocus: Locks focus on the stars instantly.
  • Extreme resistance: IP53 sealing against rain, dust and freezing (-10°C).
  • Intelligent super resolution: Photos of up to 80 MP that compensate for the movement of the stars.
  • Night vision: Screen in red tones to avoid dazzling you in the dark.
  • Nebula Capture: Special filter that reveals the intense reds of the deep sky.
