Lewis, I was referring to the post-flattener back focus distance, as I'm looking for at least 123 mm (or more) whereas typical flatteners for the ED80 are designed for T-mounts (55 mm).
To clarify for any potential purchasers - if you're using a DSLR, a OSC CCD, or a mono CCD with FW, you'll most likely be fine.
Please PM me with any further questions or comments. Let's keep this thread sale relevant as per the IIS terms & conditions. Thanks everyone!
