ZWO ASI071 Pro Cooled Color CMOS Telescope Camera
ZWO ASI071 Pro Cooled Color CMOS Telescope Camera
The Sony IMX071
- The most popular Sony sensor!
- APS-C (1.8-inch) 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.
DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.
ASI071MC Pro offers very good performance for astrophotography. Low read noise, and high dynamic range.
The Dark Current of ASI071MC Pro is better controlled with the help of DDR buffer and new improvement of hardware design.
Please check this 300s dark frame free of amp-glow.
The peak Q.E. value is approximately 50%.
The ASI071 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 ASI071 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.
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..

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!
So far so good
I ordered this camera and a filter. OPT packaged them very well and shipped same day. I've only had it out once, but with better results in less time than I ever had with my DSLR. As usual, it has been mostly cloudy since receiving the camera, but I was able to do a lot of testing as well as building my dark library. This camera is a great and logical step if your coming from a DSLR, or even if you already have a cooled camera and just want an APS-C sensor. It is well built and lighter than my Canon t1i. The low noise, full well depth and dynamic range are really appreciated when you start stretching on post processing and don't see the noise get out of control. I highly recommend this camera now, and I doubt that will change in the future.
ZWO ASI071 Pro
The Good: Overall, excellent camera. Capable of taking images probably about as good as you are going to get with a CMOS OSC camera. 14 bits provides ample detail. USB3 has rapid downloads of 16 MB images (<= 1 sec). The ZWO IR Cut filter dramatically improves star size and sharpness. X2 driver integrates flawlessly with The SkyX Pro and SharpCap. The Bad: Prone to frost or dew issues even with the heater on and/or issues with cooling performance with warmer ambient temperatures. I have two of these because one is having its cooling section repaired which has to be done in China. I also had to return one because it came with dust on the sensor out of the box. I suspect this is typical for such cameras.
Perhaps the best cooled one-shot-color CMOS camera?
This camera is so good, it is difficult to overstate its ability. Let’s just say, if you are looking for an APS-C size CMOS camera with excellent cooling, vivid color, very low read noise, high sensitivity, a smooth background and a large dynamic range, this may be the one shot color camera for you. This camera shows what is possible with OSC!
ASI 071 Pro Cooled Color
Excellent! I am fairly new to imaging and have worked my way up to this camera. What a delight. It is paired with a 104 mm refractor and .8 field flattener/reducer. Taking avi with some impressive (for me, anyway) images of the moon (got one already framed and on the wall!). Jupiter was pretty nifty as well. Captured M13 in the same field as ngc 6207. Even with a 3/4 moon and street lights, it was not difficult to remove the minor noise and glow with Lightroom curves and still retain the "wow" factor. I am looking forward to a long friendship with this camera!.
I HAVE ONE OF THESE ---THREE OTHER CAMERAS INTO MY HISTORY--THIS FOURTH ONE IS THE BEST EVER
For the money this camera brings extremely good home bound astrophotography to the front of the pack of many competing brands. I have this attached to a 12 inch Meade LX-200. I have viewed many other brands and models on this site for prices approaching $50,000. Why spend that kind of money compared to the ZWO ASI 071 ?? It is really a truth telling thing to place this website presentation of the camera alongside the other units priced so high. Here is a question....Isn't life short enough, and shouldn't you focus on what this camera gives for the low price it is offered for??? I am glad ZWO has designed this unit so well and made it available to us all at this price. I very near wasted my time on the other three cameras in my past. People like me, who are not rich, but love astrophotography would be wise to give this a critical evaluation as to what you are getting for the price paid. I say .....excellent job to ZWO !! keep it up. Reality can be the opposite to entropy...if you care. DR
