The ASI071 is an excellent full-color CMOS astronomy camera for the discerning astronomer who seeks a high power camera optimal for deep sky imaging. The sensor is an impressive and respectable 28.4mm diagonally, and provides a pixel array of 4944×3284. It’s a great choice for any kind of imaging, and works especially well for deep sky imaging. The sensor is a Sony IMX 071, which is a high level APS-C format sensor. The size per pixel is 4.78 microns.
One of this cameras greatest features is its incredibly low read noise and gain, averaging 2.3e at 24db gain. What this means is that it accrues interference very slowly, and can be active for long periods of time with minimal need to worry about trash data. This is compounded by the high power cooling system that lets the camera stay active for long periods of time without overheating. It is these features that make this camera excellent for deep sky imaging; it can take as long as it needs to capture as much data as you want.
ZWO ASI071MC Pro Cooled Astronomy Camera
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
Please check this 300s dark frame free of amp-glow:Here
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 Port: Provide 5Gb bandwidth to make it possible for ASI071MC Pro to run at 10 fps (14bit, normal mode) at full resolution(16Mega).
We recommend using a 12V/3-5A or more DC adapter for cooler power supply (2.1×5.5, center positive).
Using a battery with 9-15V is also suitable for the cooler power supply.
USB 2.0 HUB: Can 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 mechnical design and Anti-Dew Heater
ASI071MC Pro Camera completely upgrade anti-dew and mechnical 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 and no dew or frost happen on sensor anymore.
▶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.
