Logo-of-071 pro(最新)

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.

071Pro Gain RN DR FW vs gain

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

071Pro DC vs TQE 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 !ASI094-tilt-adapter-3mm

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.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.

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.

    • Sam Wen


      Hi Glenn
      we already delivered some ASI071 and next batch will be end of next month as we are having Chinese New year soon

  15. :

    Hi Sam.
    I have a possible high speed videography application. Trying to decide whether this or the MC1600 would be better. Can the ADC be switched to 12 and/or 10 bit output mode for a bit faster framerate on this model?
    Also some information about ship date based on an order this week would be helpful for us to choose.

    • Sam Wen


      no, there is no high speed for this sensor,we are having vacation soon
      so Orders placed after 21th Jan will be sent around the end of Feb.

  16. :

    Hi, I would know if Asi071 in binning 2 the information about color remain.
    And I would know if you will make Asi071 mono.

    Thanks in advance.
    Best regards

    • Sam Wen


      you can choose mono bin and color bin through ASCOM
      there is no such mono sensor

  17. :

    Sam, is the front plate tilt adjustment?

    • Sam Wen


      yes, you are correct

  18. (verified owner):

    Good to know tilt adjustment is available! I think you should put that in description :) it is a good feature!

    I placed an order, when will the new batch ship? Thanks again!

    • Sam Wen


      we will, next batch will be end of this month

  19. :

    Hi Sam, just bought a 071 and should be delivered to me by the end of next week. Just a quick question, can the camera be set to take dark frames automatically and apply them to each image taken. Having no shutter I don’t know if it is possible! If so what are the limitation , if any, in term of time or any other you may know. For example, I know some DSLR can and do it but for a maximum of 30seconds. Thank you. Luc

    • Sam Wen


      yes, you can use sharpcap and enable dark subtract function

  20. :

    Hi Sam. what binning modes are supported? 2×2, 3×3, 4×4? Color and/or mono binning?

    • Sam Wen


      hardware binning 3*3 only and color binning
      software binning 2*2 3*3 4*4 and color and mono binning both supported

  21. :

    Is it possible to remove the AR Filter and to replace it with an IR Filter?

    • Sam Wen


      no, the AR filter is glued to the cover

  22. :

    Does this camera require a UV/IR cut filter and if so what is the best size? Using it with a 10″ F4 Newtonian, RC8, and ED80.

  23. :

    When are you going to release that rumoured ASI094 full frame cooled CMOS camera? Is it monochrome or colour? I would like to test it.

    • Sam Wen


      we are going to release this month Sep

  24. :

    When are you going to release ASI071Pro ?

    • Sam Wen


      soon, next week

  25. :

    is the dew problem solved?

    • Sam Wen


      the new mechanic structure can seal the camera better and keep CMOS chamber dry longer

  26. :

    Is it better to place the IR-Cut-Filter near to the sensor or away from the sensor in order to avoid reflexes?

    • Sam Wen


      of course away from the sensor

  27. :

    1. Is the anti dew heater on the protect window turned on by default?

    2. Which software has the necessary controls to turn the heater off?



    • Sam Wen


      yes, you can control it in ASCOM dialog

  28. (verified owner):

    Hello, when will this camera be available for delivery?

    A greeting.

    • Sam Wen


      middle of Nov

  29. :

    Hi, you writing the camera ASI071MC Pro is available on backorder. When i’m ordering now, when will you deliver?

    • Sam Wen


      we can deliver this week, we just have it in stock

  30. :

    Hi, is the darkframe on the web-site really 300s long ? Because I see no hotpixel or noice.

    • Sam Wen


      yes, that’s 300s dark
      the noise is so low and you need to stretch the image very hard to see the noise

  31. :

    Hello just got my asi071 pro had to reinstall ascom driver as was not working. I notice that the offset slider bar is gone when using ad
    Scom based sofware is this OK. Or I’m a missing something, the gain slider is there.
    Otherwise camera works fantastic..

    • Sam Wen


      because you don’t need the offset and usb bandwidth any more with the “Pro” version
      the offset is always fixed at one reasonable value

  32. :

    I have problems with the temperature sensor of my new ASI071MC Pro (I received it on 5.12.).
    The first week, everything worked fine (e.g. making fotos @ T=-20°C), taking darkf frames… everything perfect. .
    But since 16.12. the following happens:

    1.) I set a target (desired) temperature of <10 °C. 
    2.) Cooling starts and the temperature goes down constantly (that's great).
    3.) When reaching T<10 °C, the temperature readout suddenly jumps to a number between T=70-110 °C! 
    At the same time, the cooler power goes up to 100% and then stays constantly at 100%! 
    4.) After 30 minutes, the temperature still shows the same temperature (e.g. 105 °C) and cooling power is still 100%. 

    There is something wrong with the temperature sensor ?!

    Best regards

    • Sam Wen


      this is a hardware problem, we already contacted this customer and get the camera back for repair

  33. :

    Hi! I have a quick question about focus when using camera lenses… I tried the T2 adapters sold by ZWO for all three brands — Canon, Nikon and Sony — and was not able to reach focus on any of them. Is there another adapter or spacer required for the ASI071MC Pro to reach focus on camera lenses?

    • Sam Wen


      The SONY adapter won’t work with 071
      but Nikon and Canon lens must can, you need to adjust the focus position of your lens

  34. :

    Hi Sam,

    Any way to get a batch of 071 mono sensors for some mono ASI071 Pro’s? The well depth and dynamic is amazing!

    • Sean Wang


      Hi James
      We didn’t plan to do that, it’s not a stable version for users.

  35. :

    Hi Sam,

    I got my asi071 after a long waiting time of three month and I’m very impressed. The camera has really very poor noise and great colours of pictures end-results. Currently I can’t find any weak. Great camera! Thanks for making it.

    • Sean Wang


      Thank you very much! Kai-Oliver. Your kind words inspires us all.
