ASI585MC/MM Pro Deep Sky Camera

The ASI585MC/MM Pro is ZWO's new deep sky camera featuring a 4K SONY CMOS sensor with 1/1.2″ format and 2.9μm pixels. With super high sensitivity and 3840×2160 resolution (8.29MP), it delivers fast frame rates up to 47fps at full resolution with low read noise. This entry-level DSO camera offers excellent cost-effectiveness with high SNR and near-infrared sensitivity.

Power Requirements

Note: All ASI-cooled cameras require external power. We recommend using a 12V@3A~5A DC adapter (D5.5×2.1mm, center pole positive) or 11-14V lithium battery. Using power outside this range may permanently damage the camera.

Why Choose ASI585MC/MM Pro?

Versatile Imaging Capabilities

STARVIS 2 technology provides advanced imaging performance for both deep-sky objects and solar/lunar/planetary photography thanks to its high frame rate.

Sample Astrophotography

Large Full Well Capacity

The back-illuminated structure provides 40ke- full well capacity (3× greater than IMX485 sensors), improving light collection efficiency and preventing highlight overexposure while enhancing signal-to-noise ratio.

Zero Amp Glow Technology

Hardware-level amp glow elimination ensures clean dark frames regardless of exposure length or gain settings.

512MB DDR3 Memory

Built-in cache combined with USB 3.0 interface ensures stable high-speed data transmission.

Dual USB Connectivity

• USB 3.0: 5Gb bandwidth enables 47fps at 8.29MP resolution
• USB 2.0 Hub: Supports accessories like filter wheels and focusers

Two-Stage TEC Cooling

Cools sensor to 35°C below ambient (at 30°C), significantly reducing dark current during long exposures.

Note: Cooling performance varies with ambient temperature and duration.

Camera Performance

Low Noise with High Dynamic Range

HCG mode automatically activates at gain 200, reducing read noise to 0.7e while maintaining 12bit dynamic range.

Quantum Efficiency

91% peak QE for exceptional light sensitivity.
