      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?

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

    • Sam Wen


      no, the AR filter is glued to the cover
