    I own this adapter and it took quite a while to figure out what is included and how it can be used to reach a certain backfocus distance. Can you please include a drawing like this one https://astronomy-imaging-camera.com/wp-content/uploads/EFW2-EOS-3.jpg and mention what is included despite the adapter itself? I also received a M54-M42 extender which is 5mm thick and can be removed.

    Can I use this to get 55mm back focus for ASI 2600mm Pro to connect to EF lens? 2600mm (17.5mm) + 36mm EFW (20mm) + this adaptor (17.5mm) = 55mm

    Hello! This adapter comes in 2 pieces. If I remove the plastic piece from the back (M42 side), is the other piece the exact same as ZWO EFW2-EOS, which connects Canon lens to M54 (2-inch filter wheel) and is 11.5mm thick?

    I tested the Zwo adapter with a h-alpha filter. So, they do not give focus with canon lens (only in LRGB). Is there other adapter shorter, to work in hubble pallette? Thanks for reading.

    How do I thread a single 2 inch astronomic HA 12 no filter into the EOS adapter using an asi 2600mm? The 2600mm manual suggests this can be done, but I don’t know where the filter actually goes in? The diagram in the camera manual is confusing and doesn’t really specify how it gets inserted.

    I wish to use a Pentax 150-450mm FF lens possibly with ASI294MM & EFW 36/7. I can get a Pentax K to Canon EF adapter which seems to be around 1-2mm. The EFW and camera total is 26.5mm. I cant see the distance of this adapter. I assume it must be around 18mm?

    Does the adapter work with EFW Mini only or also the bigger 7 and 8 position wheels? I would like to connect ASI1600MM PRO with the bigger EFW to a Samyang 135mm EF lens.

    I have Asi1600 MM-P camera, ZWO EFW filter wheel (8 x 1.25 ″) and Canon EF-S lenses.

    Is there any piece that allows to use the new generation of Eos adapters, for Canon EF-S lenses?

    Does the older generation of Eos adapters allow use with Canon EF-S lenses?

    When using this on a 183 Pro do I also need an 11mm spacer or a filter wheel?
    Is this correct?
    Thank you!

      Yes, you will need an EFW but do not an 11mm spacer.
      If you want to connect the Canon lens without EFW, you can refer to this link:

    Can we get a version that includes an OAG prism built-in? Possibly pre-spaced for asi120mm+canon backfocus requirements? I’m unable to find a way to OAG+EFW on a Canon or Nikon lens. Even an optional pre-drilled prism hole would be lovely for using the prism from the ZWO OAG!
