The ZWO ASI585MM Mono is a monochrome camera for astrophotography with impressive sensitivity, resolution, and speed – ideal for capturing every detail. Thanks to the advanced Sony IMX585 CMOS sensor, this camera captures razor-sharp images of the moon, planets, and deep-sky objects like nebulae and galaxies.
What sets this camera apart is its amp glow-free sensor. This means: no disturbing glow during longer exposures, resulting in a cleaner and sharper image – even in dark parts of the capture. The fine 2.9 µm pixels ensure maximum detail at f/10 without needing a Barlow lens. And although the camera doesn’t have active cooling, temperature remains controlled thanks to smart heat conduction via PCS.
Key Features
- Sony IMX585 sensor (8.3 MP, monochrome) – resolution of 3840 x 2160 pixels
- Amp glow-free sensor – no disturbing glow during long exposures
- Pixel size of 2.9 µm – perfect for f/10 telescopes like Maksutovs
- Frame rate up to 47 fps – ideal for stacking and real-time observation
- Smart heat conduction (PCS) – sensor stays cool without active cooling
Applications
✓ Planetary and lunar photography with maximum sharpness
✓ Capturing solar disk in detail (with suitable solar filter)
✓ Deep-sky astrophotography without amplifier glow
✓ Infrared imaging to reduce atmospheric turbulence
✓ Suitable for EAA and autoguiding
The ASI585MM is an excellent choice for photographers who prefer working with monochrome images for maximum control and sharpness. Thanks to the absence of color filters and high sensitivity, this camera delivers exceptional raw data for stacking, post-processing, and scientific applications.
