Camera Sensor



  • 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.

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).

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

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.螺丝

▶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, however you can order one from 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 turn off  in software to save power.

    Hi ZWO, I purchased the ASI071MC-PRO and I take a dark library now at unitygain/-10°C. What I observe is that the temperature of the senor is fluctuating, so 1/8th of the frames come in at -9.4°C and 7/8th frames come in at -10°C. Cooling is at 57% and the antidew feature is turned on.
    Something to worry about?

    Thank you for the advice…

    In the specifications it is mentioned that the ASI071 can accept a 9-15V battery for the cooler. Is there a recommended battery attachment that will hold a small battery and be compatible with the power supply port on the ASI071?

    10 inch f/10 lx200 GPS meade sct scope . If I use a 6.3 focal/ reducer to bring the f/10 to f/6.3 would the 071 camera be a good fit for this scope or is there a better camera that would be better for this scope for DSO.

      Yes it can.

    I have a 10 inch f10 lx200 GPS meade sct scope. Im looking at a camera and I was thinking of this asi 071mc pro camera . would this be a good fit for my scope. I would like to image galaxies and nebulas and would I need the IR filter

      Actually, this telescope is not suitable for DSO, F/10 is too long.
      You could use 071 but we are not sure about the performance with this telescope.

    Good morning, the ASI071MC Pro is working well but I am unable to receive color and all images are in gray scale. The software I am using to capture is APT… I go to settings and it directs me to the ZWO setup screen where I can select RGGB or Mono bin. I leave the Mono Bin unchecked but only get the Gray scale images.

      Please debayer the images in the post-processing.

    Hi, I’m about to switch from DSLR to CCD and am considering ASI0171MC Pro. i have these questions:

    1. software: will it be ok to use it with a Mac? in terms of driver and capturing software compatibility. what capturing software is recommended for mac and zwo? is INDI a must to run cos i never use INDI before.

    2. adaptor and other hardware: i’m using a Tak FSQ85 and a WO Zenithstar 61, is there any extra adaptor i need to have ASI071 to work with my setup?



    • Sean Wang


      Hi Nick
      We have drivers and suitable thridpart softwares for Mac. I think Nebulosity is good for you. INDI and INDI library need to be installed. We get all links of them on our website.
      ASI071 have 2″/M42/M48 adapters, so I think it can works with your telescope without any extra adapters.

    Thanks for the answers to all these questions. They are helpful, you may want to put a “like” and a “helpful” button on the comments, this will help you find out which questions are more useful to update your data on other camera sections.

      Thanks, Hemant. It’s a very good suggestion, we will consider about it. Thank you very much.
