ZWO ASI585MM Pro 8.29MP USB-B 3.0 Cooled Monochrome Astronomy Camera

New DSO Camera with High Sensitivity
ASI585 Pro is a new ZWO deep sky camera based on the 4k SONY CMOS sensor with a 1/1.2" format and 2.9microm pixels. It has a super high sensitivity and a large resolution of 3840x2160 (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.

ASI585 Pro One Camera for All
Its high frame rate makes it not only suitable for DSO photography but also solar/lunar/planetary photography.

STARVIS 2 Backlit Sensor
The sensor technology offering a high sensitivity that exceeds human eyes

4K resolution High resolution images
• Resolution: 3840 x2160
• High speed mode: 47fps

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.

Large Full Well Capacity
The back-illuminated structure provides 40ke- full well capacity (3 x 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 Degree C below ambient (at 30 Degree C), significantly reducing dark current during long exposures.

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%.

Note: External power supplies are needed for all ASl-cooled cameras. We recommend you use a 12V@3A-5A DC adapter (D5.5 x2.1mm, 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.
