    Hi!
    I have an ASI 1600MM-Cool and the 8-slot filter wheel with 31mm filters. Will this adapter work for all types of Canon lenses with that combination? I am planning on using it with my Canon 300/4L tele lens.

    Hi Sam
    I have the ASI 1600MM cool and mini EFW.
    I have been using the EOS adapter to connect to the Canon adapter on my telescope.
    But the EOS Adapter has developed some play (about 1mm) between the EOS adapter and the Canon adapter.
    This means the camera is not aligned properly anymore as the EOS adapter is not tight to the Canon adapter on the top side.
    The weight of the ASI 1600 is pulling the gap open.
    Is there away to remove this slackness from in-between the two adapters?
    Has this been reported before?
    If I cannot remove the play that now exists I will have to use a solid connection between Mini EFW and scope.
    Thanks

      EOS adapter is not tight enough

    I have ASI1600MM-C+EFW so I know this adapter will work to have Canon EF lens. I also have ASI290MC. Can I use this adapter with spacers on my ASI290MC? I do not want to buy two EF adapters if I can use the short one with spacers (I have many extra spacers of various length).

      you can add one spacer to make the EOS adapter works on 290MC

    I have the EOS-T2 adapter but the mounting ring is too thick for my filter wheel. The mounting ring on the back of this adapter is thin and would work with my filter wheel. Could I order just the mounting ring (59mm female to T thread male) only?

      sorry, this adapter is only used for our EFW and 1600
      the thickness of our M59 female to T thread male is not correct for you

    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

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

    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 ?

    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!

    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)?

      :

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

    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?

    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.

    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

    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.

      :

      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

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