I have been having issues with spacing and reaching 55mm from the chip to the field flattener, and I bought a caliper to measure my imaging train, and it turns out that the OAG is 16mm, not 16.5mm. Since I don't want to take it apart to verify, are you SURE the ASI071MC-Pro is 17.5mm like it states in the documentation? I have bought spacer rings to get me to 55mm after introducing a UV/IR cut filter into the train, and I would like to not buy any more spacers if I don't have to
