    Please, I don´t have Pay Pal, and I want to buy the asi174mc-cooled at Ali-Express (with my Visa), but this camera is not for sale (when?).
    Thanks and best regards,

    • Sam Wen


      Hi Martin
      we will upload this product to Aliexpress next week

    I am going to purchase the asi174 cooled and see that a 12v adapter is recommended but does not appear to be included. Where do I get one? Also, what accessories do you recommend for this camera? Thank you

    • Sam Wen


      Hi James
      you can get this adapter in your local market, 12V@2.5A and more is suggested
      I think you don’t need other accessories to connect to your scope

    In your opinion is the 174 model the best camera for deep sky and planetary imagining? I am interested in doing both

    • Sam Wen


      yes, we think this is the best suitable for doing both 😉

  4. :

    I have the ASI120MC. What is the difference between that camera and this one (ASI 174MC)? Will this camera (ASI 174MC) work as well with FireCapture software? Same frame rate, etc.? Thank you!

    • Sam Wen


      the sensor on ASI174MC is 4x larger as ASI120, the max fps is 164 at full resolution
      all ASI cameras can run under Firecapture

  5. :

    Is it possible to save the data in fits format(monocolor)?
    I wonder this camera can take the data both color and monocolor.

    • Sam Wen


      Yes, most software support fits format

  6. :

    I would like to the performance difference between 174mc cool color and 174mc cool mono.
    Which camera is better to take the 16bit data for scientific research?

    When I saw the Sharpcap software using asi174mm, the program shows the depth of mono8 and mono16.
    We uset the sharpcap software in the setting of mono16(0-65535DN) and fileformat of fits(not ser format)

    I hope to reply your answer.

    • Sam Wen


      there is only 12bit ADC with 174, and the lowest 4 bits are 0 if you choose mono16

      maybe ASI1600 is more suitable for scientific research

  7. :

    Does this product comes with IR filter? Am I able to attach or detach the IR filter easily?

    • Sam Wen


      yes, it come with IR-CUT filter
      but it out of stock right now

  8. :

    I have Meade 16 inches scope and I want to get ASI 174mc COOL, do you think it is a good choice of camera?

    • Sam Wen


      yes, you can use this camera
      but seems we don’t have in stock right now and need a long time to produce
      you may can consider ASI1600MC-Cool

  9. :

    I’d like to buy ASI 174mc COOL. Any estimation by when it will be available again ?

    • Sam Wen


      we have the uncooled one instock, but we feel it is not very suitable for cooled DSO imaging
      maybe you can choose ASI1600MC-Cool

  10. :

    Hello there. I’m looking to buy the ASI 174MC-Cool (color) or the 178 cool color. I have a Celestron C8. I’m interested particularly on videos capture. I use at the moment a mirror less sony camera 3000. I have also modified web cams that i use in different situation set up.I have done most with the sony so far as the best giving result. I miss a camera that can do the same ….actually better. Is the ASI 174MC-Cool (color) a video camera? Also i see you have a good price here in confront to others sellers….so when the ASI 174MC-Cool (color) will be again available for buying? Also for video takes of moon and planets which one is the best from the two. Hope is not too many questions…tanks in advance:-)

    • Sam Wen


      I would recommend our ASI1600 for DSO imaging as 174 has amp-glow
