Product Description

The ASI071MC Pro is a popular OSC camera based on the highly appreciated sensor from Sony – the IMX071 – in APS-C format. A good set of specifications combined with a good price makes it a great choice for those who want to take the step from DSLR to a dedicated astronomy camera.

If you are looking for an APS-C type OSC camera for astrophotography, you can't go wrong with the ASI071MC Pro. It will provide low read noise and a high dynamic range.

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 controlled than before with the help of a DDR buffer and new improved hardware design.

QE Curve

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

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

USB 2.0 HUBCan connect with various accessories, including a filter wheel, guide camera or electronic focuser, allowing you to manage your cables better. There are two short 0.5m USB2.0 cables included with the ASI071 Pro. The hub is powered by the external power supply if you connect one.

New mechanical 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 increased to 86mm compared to the ASI071MC Cool (78mm).

Anti-dew and cooling system

Thanks to the two-stage TEC cooling, ASI071MC Pro can lower the CMOS sensor temperature to more than 35-40 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.

Please note that the camera needs to be connected to an external 11-15v power supply to implement the cooling function. We recommend you use 12V@3A DC adapter (5.5*2.1mm, centre pole positive) or lithium battery with 11-15V to power the camera. There are 4 different standards for different countries, please make sure you selected the correct adapter when placing the order.

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.
