Product Description

Latest version

small cooled 600x600 178MC-COOL1

Our brand new cooled version of ASI178MC Color Camera  allows the sensor to be cooled to 35C to 40C degrees below ambient!

Here is a 60s long exposure dark file of this Camera

Back-illuminated  CMOS Image Sensor with 14bit ADC.

ASI178MC has a 1/1.8″ and 6.4M pixels sensor IMX178 with SONY STARVIS and Exmor R Technology.


Extremely low read noise(2.2 e – 1.4e ) , high sensitivity and 14bit ADC make it very suitable for astronomy and microscopy high resolution photograph.

This camera can run without external power supply in normal mode.

we recommends 12V at 2.5A or 3A  minimal DC adapter for cooler power supply.


What`s in the box?


Notice:Cooled cameras need a 12v power adapter, If you don’t have one, please click this link to buy a 12V power adapter. There are 4 different standard for different contury, please choose it carefully.

    I have had 2 sessions now with this camera and am having a couple of problems. I am using Nebulosity 4.0.4 to capture and process.

    1. Colour balance: after some trial and error, it looks as though I should be using offsets of X=1 and Y=1 when debayering to create a colour image from FITS file. Could you confirm?

    2. Up until now, I have been using modified Canon DSLRs (usually 1100D), mainly at ISO 400 or 800. During my capture sessions I used Gain of 20% and then 50%, but do not seem to be getting to anywhere near the sensitivity of the Canon DSLRs at ISO 400. For example, the blue nebulosity around the Pleiades stars is extremely faint even at 50% and can only just be separated from the noise level. Do you have recommendations for the Gain level, to approximate ISO 400 and 800 with Canon DSLRs?



    • Sam Wen


      Hi Graham
      1.the bayer patter is RGGB, I am not very famliar with nebulosity, so cannot say you are right or not, but its very simple just try it with the lens at daytime
      2.this is because the pixel size of this chip is very small, so you cannot compare directly to a different pixel size camera
      you know 178 bin2 mode is still smaller, that’s why it’s so faint, I think you can try bin2 mode

    I would like to know if you have this product in stock, and what is the delivery delay for Canada?

      this product will be in stock next weekend

    I have placed an order for the 178 MC back in February 2016 from a reseller in Canada. I hope to receive it soon! In teh mean time, i’m reviewing thr options to attach the camera to my telescope.

    So, is it possible to attach the 178 to the end of a standard T2 adapter (say from Celestron)?

    Dominique Martel

    • Sam Wen


      Yes, there is T2 female interface of all ASI cameras body

    For the purpose of taking dark frames for calibration, can you tell me if the Rolling Shutter of the 178 MC is electronic or mechanical.

    Dominique Martel

    • Sam Wen


      it’s electronic rolling shutter

    I did not see power cable (for cooling) in the product description. Do you provide power cable with the product? What socket/adapter shall I use for the power cable?

    Richard Ren

    • Sam Wen


      Hi Richard
      we didnot provide power cable because the socket of different country is different
      you need 12@2a minimal DC power supply

    Hi Sam,
    I guess between ASI 178MC and ASI 1600MC, I can only by the former as my mount only has an ST4 port. I am new to astrophotography, can I use this camera to capture the picture and auto-guide the mount at the same time? Or, the picture-capture and auto-guide use different software and therefore cannot share the same camera at the same time?

    Thanks a lot,

    Hi ZWO,

    What would you recommend for this camera to counter light pollution?
    I currently use a Canon D1100 with a clip idas hutech lps v4 filter, is there something similar available for the ZWO camera?
    Unfortunately, I have to do most of my shooting in the city. And does this camera use a similar T2 ring as I currently use to connect my Canon to my telescope?



    • Sam Wen


      I think you can consider our ASI1600MC-Cool
      it come with T2 rings
      a cooled camera is far better than uncooled one

  8. :

    Hi Sam,
    Thanks for all the information! I only have about $1000 budget and think of either buying ASI1600 MC-cool or ASI 178MC-cool+autoguuide camera. Now it seems that either of your camera can do two tasks simultaneously.

    Just be curious, won’t the long exposure interrupt the autoguide function of your camera?

    • Sam Wen


      the camera cannot run as guider camera if you use it for long exposure
      but you can control the ST4 port seperatly

  9. :

    What is the power connector size on the cooled cameras?

    • Sam Wen


      it’s 5.5*2.1

  10. :

    Can the IR-CUT window be dismantled?

    • Sam Wen


      we don’t recommend you do it as the CMOS chamber is sealed

  11. :

    Hi Sam
    I have a 178MCC and want use my Nikon Lenses. Is it possible with the backfocus to built it with 178MCC + Filterweel+EOS Adaptor + ASINikon?
    PS: Why you not provide a shorter M42 topplate in front of the sensor? Maybe in the future?

    • Sam Wen


      is it mono or color camera?
      you can contact us to get the shorter cover just like on 1600
