      The asi1600 can be directly connected to EFW without adapter.If you have Nikon lens,this is exactly the adator you want.The following is the connection method:ASI1600+EFW+EFW-Nikon adapter+Nikon Lens.

      Yes it can achieve focus, maybe you can add some spacers to adjust the back focus?

    Dear Sam, when using my 1600 pro and the EFW, this adaptor and a nikon lens, I cannot get it to focus no matter what combination of extension I use.Is it because I am trying on distant terrestrial objects during the day?Also this adaptor seems to work well on some Nikon lenses and on others its very hard to attach, is this normal? Thanks.

      You can try to add or recude spacers that comes with 1600MM pro camera to adjust the back focus.

    Hi, Nikon F mount flange back is 46.5mm
    ASI1600 6.5mm + EFW wheel thickness 20mm + Nikon To EFW 20.5mm = 47mm > 46.5mm…
    Does it work ??

    Without the extension, what size thread is on the lens adapter opposite the lens? Is this m48? And is it male or female.
    Thanks!

      It is a Nikon lens adapter for EFW, so it is designed for Nikon lens, it requires Nikon lens.

    Thank you for your answer Sam concerning the thread specification above.
    Unfortunately there is a misunderstanding. I know that the Thread towards the camera is M42x0.75.
    What I wanted to know is the thread in the middle of the adaptor where you combine the two parts of the
    adaptor .
