  1. :

    What is the back focus spacing on this thinner adapter?

    • Sam Wen

      :

      this is designed for 1600 and our EFW especially
      so the back focus is 6.5+20=26.5mm

  2. :

    I am buying the 1600mm cooled camera. I have a 1150mm f4.5 Newtonian telescope. Am I likely to need a coma corrector with this setup?
    Thanks

    • Sam Wen

      :

      yes, you need coma corrector for 4/3″ format camera

  3. :

    I have a 25mm 7-position filter wheel I would like to use with the 1600. The camera is 6.5mm. So, 6.5mm + 25mm + EOS adapter = ??
    Will this work? Or, are you coming out with a 7-position 20mm filter wheel sometime? What is the back spacing of the EOS adapter? Thanks.

    • Sam Wen

      :

      the back space of the EOS adapter is 44-26.5=17.5mm
      so you cannot use our EOS adapter with your filter wheel
      yes there will come a big EFW with 7 or 8 1.25″ filters

  4. :

    I have a QHYFW2-M-US and one directly connected to the ASI1600MM the back focus appears to be 26.25mm. What is the back focus tolerarnce? Is off-by 0.25mm going to be a problem?

    What type of connector does the adapter use to connect to the filter wheel?
    (i.e. T-thread, male or female etc).

    Thanks

    • Sam Wen

      :

      the back focus tolerance should be 0.5mm
      so 26.25 should be ok

      the connector to connect EFW is T2 male

  5. :

    I’m an happy owner of ASI1600 MC-C, is it available a similar adapter for Pentax lenses?

    • Sam Wen

      :

      maybe you can use Pentax to EOS adapter

  6. :

    Do you sell spacers to get to 44mm of back focus. I want to use this adapter on your color CMOS so don’t need a filter wheel.

  7. :

    I own an ASI 178mm camera, and an ASI manual filter wheel.
    From what I read, the adapter for “all ASI cameras” has not enough backfocus for filter wheel use, will this one be ok instead, even if it says it’s for 1600?

  8. :

    it’s 44-20-6.5=17.5mm

  9. :

    That should have said what is the thickness of this adapter please. Also will it work with your manual filter wheel.

  10. :

    What is the recommended maximum lens weight when an ASI 1600 camera is screwed to a tripod using the new holder ring for ASI cooled cameras and using the ZWO 8×1.25 EFW? Can it suppor the Samyang 135mm f/2 lens (830g)?

    • Sam Wen

      :

      I think it’s better to use 2 rings and one dovetail
      SamYang 135 F2 is too long

  11. :

    The photo shows only a female thread. Does it come with an adapter that gives a male T2 thread? I don’t have the EFW yet, it is in my upgrade list, but I was wondering whether I could get this part now and use it with my old 1.25″ nosepiece camera (I have a T-thread to 1.25″, but it needs a male T-thread to screw on). Thanks!

  12. :

    I am a very happy owner of the ZWO 1600 cooled monochrome. I have taken fantastic picture with my SCT 8″. I would like to take wide angle images of the sky with narrow band filters. I have the orion 5-position filter. It is manual. Will the back focus allow for this filter and the lens of Canon Rebel 450 to attach to my ZWO ? How thick is your EFW ?

    • Sam Wen

      :

      our EFW is 20mm thickness
      ypu’d better pick up our EFWmini

  13. :

    Is it possible to use an EOS lens with the 1600mm+efw mini+Lps filters? I have a 2″ filter but not sure where it would go in the train with the EOS lens

    • Sam Wen

      :

      seems it’s not possible
      maybe you can get the 2″ filter glass out and put it into the EOS adapter?
