ASI071MC Pro

Camera Sensor

▶IMX071

• Most famous sensor of Sony
• APS-C(1.8″) Diagonal 28.4mm
• 16M Pixel (4944×3284)
• Very low read noise: 2.3e @24db gain 3.3e @lowest gain
• 14Bit ADC: provide real 14bit Dynamic range
• Electronic shutter: no vibration problem with mechanical shutter

DDR Memory Buffer

ASI071MC Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.

DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

Astrophotography Performance

ASI071MC Pro offers very good performance for astrophotography. Low read noise, high dynamic range.

Dark Current

the Dark Current of ASI071MC Pro is better controled than before with the help of  DDR buffer and new improvment of hardware design

QE Curve

We suppose the QE peak value is more than 50%.

Relative QE curve

Unique Tilt Adapter

ASI071 Pro includes unique tilt adapter. Say goodbye to tilt problems forever !

USB 3.0 Port & USB2.0 HUB

USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI071MC Pro to run at 10 fps (14bit, normal mode) at full resolution(16Mega).

New mechnical design and Anti-Dew Heater

The ASI071MC-PRO camera comes with a completely upgraded anti-dew and mechanical body.

The diameter of the camera body is incresed to 86mm (ASI071MC-Cool is 78mm).

▶6 screws seal the chamber

This new structure seal the CMOS chamber better.

▶anti-dew and cooling system

ASI071MC Pro has a two-stage TEC cooling system that allows deep cooling (35°C-40°C below ambient). You will need an external power supply to power the cooler. An AC-DC power adapter is not included in this package.

The anti-dew heater will heat the AR protect window to avoid any dew problems. The heat anti-dew heater power is around 3.6W and can be turn off  in software to save power.
