ASI585MC/MM Pro Deep Sky Camera

ASI585MC/MM Pro is a new ZWO deep sky camera based on the 4k SONY CMOS sensor with a 1/1.2″ format and 2.9μm pixels. It has a super high sensitivity and a large resolution of 3840*2160 (8.29MP in total). It also features high transmission speeds – In high-speed mode, the fast frame rate can reach 47fps with low read noise at full resolution! It also features a high SNR and high sensitivity, especially in near-infrared wavelength. Being an entry-level DSO camera, it offers great advantages of high cost-effectiveness.

Note：

External power supplies are needed for all ASl-cooled cameras. We recommend you use a 12V@3A~5A DC adapter (D5.5×2.1mm, center pole positive) or a lithium battery with 11-14V to power the camera. Be aware that using a power supply out of this voltage range will probably lead to irreparable damage to the camera.

Why Choose ASI585MC/MM Pro?

One Camera for All

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

Appreciation Work

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.

USB 3.0 Port & USB 2.0 HUB

• 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

Based on our testing results, the QE peak value of ASI585 is 91%.
