    Hi,

    I'm considering purchasing a SBIG STF-8300M camera with SBIG FW5 filter wheel and OAG-8300. I need to know which adapters are needed to fit OAG-8300 to my Pyxis 3" rotator.
    I think I'll need this: https://www.sbig.com/products/accessories/stl-cover-for-oag-8300/
    and then #17843 3-inch to STL 2.156”x 24tpi male thread adapter from Optec's catalog.
    Am I right?
    In that case, what is the back-focus usage of this 2.156" x 24 thread adapter plate?

    thanks,
    Marko

    Hi Tim,

    So there are optional OAG covers? Where can I find information regarding these?

    Marko

    EDIT: Oops, I see: the adapter plate is the "cover", right?

    The OAG-8300 bolt circle is four 4-40 screws on a 3.05 diameter (1.525 radius).

    The Optec page indicates a 1.9" x 1.9" square bolt pattern. That corresponds to a 1.34" radius. So they are not compatible.
