ZWO ASI 071 Pro Cooled Color CMOS Telescope Camera Features

Camera Sensor

ZWO ASI 071 With Sony IMX071

The Sony IMX071

  • The most popular Sony sensor!
  • APS-C Diagonal 28.4 mm.
  • 16 Megapixels (4944 x 3284).
  • Very low read noise: 2.3 electrons at 24db gain & 3.3e the lowest gain setting!
  • 14-Bit ADC: Provides a real 14-bit dynamic range.
  • Electronic shutter: No vibration caused by a mechanical shutter.

DDR Memory Buffer

The 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.

ZWO ASI 071 DDR Memory Buffer

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, and high dynamic range.

The ASI071MC Pro includes a unique tilt adapter. This is extremely useful when you need to collimate the sensor plane on fast optical systems.

USB Port &Hub

USB 3.0 Port: Provides 5 GB bandwidth to make it possible for the ASI071MC Pro to run at 10 fps (14-bit, normal mode) at full resolution(16-megapixels).

USB 2.0 Hub: Manage your cables by connecting various accessories like a filter wheel, guide camera or electronic focuser. There are two short 0.5 m USB 2.0 cables included with the ASI071MC Pro. The hub is powered by the external power supply if you connect one.

New Mechanical Design

The ASI071MC-Pro camera comes with a completely upgraded anti-dew and mechanical body. The diameter of the camera body is increased to 86 mm (ASI071MC-Cool is 78mm), and the new structure seals the CMOS chamber that prevents frosting.

ZWO ASI 071 Pro vs. Cool

Anti-dew and Cooling System

The ASI071MC Pro has a two-stage TEC cooling system that allows deep cooling (35 degrees Celsius to 40 degrees Celsius below ambient). You will need an external power supply to power the cooler. An AC-DC power adapter is not included in this package, however, you can order one here.

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. 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 turned off in the software to save power.

Upgrade from DSLR

This is definitely an upgrade and a bit of a learning curve from the DSLR. I pretty much had to throw away a night of imaging to work out a lot of details but that is to be expected. I'm using a Celestron 9.25 with the 6.3 reducer. I had done some research indicating that the proper back focus from the end of the reducer to the camera sensor would be around 105mm , so I loaded up on spacers. This turned out not to be so. After a great deal of experiment I landed at about 65mm before the vignetting finally subsided. Most of the learning curve has been around learning how the camera interacts with the computer and whatever programs you're using. To be honest, I still haven't worked all that out. Finally got a whole night of imaging in, though not ideal conditions ( 25mph wind gusts and a bright moon for half the night). I was blown away by the difference in image quality from the DSLR even in less than ideal conditions. Having never dealt with FITS image format there have been a number of other hurdles in the processing of the images that have been hair pulling. Deep sky stacker and pixensight both seem to read the images in gray scale and I had to figure out how to debayer. That word never enters your vocab with a dslr. But I'm sure I will figure all this out in time. That is half the fun of this hobby. Overall great camera so far. Wish I knew how to add an image to this review.

My first astronomy camera and it has completely sold me on the zwo experience and cooled cameras

The camera has produced incredible results and holds a -15deg sensor temp no worries all year making bias and dark libraries easy that is the reason right there to not shoot a dslr, keeping a steady temp means you never have to waste half the night shooting darks. The camera is super low noise and has a nice large chip for getting the large and dim nebula targets. I shoot mainly with the 2inch Triad Ultra and it makes collecting data and automation a breeze. Just set up plate solve and then you are money in SGP to shoot multi targets and meridian flips all while asleep. The large sensor and fov makes it an easy transition from a dslr or mirrorless with a real step up in quality. I am happy with the simplicity and ease to replace parts if needed. I have replaced the fan from corrosion from the salt sea air and have cleaned the sensor. Just easy to service no special tools. The one con I saw so far is that I developed some kind of dew or fog on the sensor and needed to open it charge the desiccants and clean the sensor and it's been great ever since. The images speak for themselves.

Loving the ZWO 071mcPro

This camera is awesome! Large sensor able to capture larger targets like M31 and the Pleiades! Camera produces clean low noise data from my Bortle 7-8 skies.

Great sensor, but watch out for condensation and icing

I upgraded from the ASI294MC-Pro, and it's hard to overstate how impressed I am with this camera by comparison. Amp glow is non existent, it has very low read noise both of which give me better data to work with at the end of the day. I'll offer one caveat to an otherwise glowing first impression. On my first night imaging, the sensor began to ice up and the front window fogged up adding insult to injury. Condensation management is critical with this camera. I bought an external dew strip offered by ASI which I view as a necessity with this camera in humid environments like mine. The built-in dew control feature must be turned on in the native driver, but it still requires the additional heating. I also dried the desiccant tablets and reassembled the camera. I haven't experienced the dew issue since, but I don't think the customer should be expected to work quite so hard to compensate for what I feel is a design weakness. Once the condensation issue is addressed however, this camera is awesome. The data is spits out is top notch!
