Just say someone had a spare 8" f6 newt, and a spare secondary from an 8" SCT.
Just say that person placed the SCT secondary somewhere along inside their Newt, and moved the Newt secondary down close to the primary mirror and reversed it.
He could then place a focuser on the OTA down near the primary and check the result.
What would he be likely to see? Would the SCT secondary work the same as a classic Cassegrain secondary?
Would he just get some smudgy smeary result?

Cheers,
Jason.
Who may have the parts to give it a try.
