Hello 4-Os,

Well anything's possible. If you want to use it without using a ladder you could consider (somewhat crazily):

1. Using a much larger secondary lower down the tube, with the attendant greater constriction, larger mounting boss diameter & length
2. Using corrective (converging) optics before the secondary. These would also be large, given the focal reduction you're after. Your own Hyperstar, so to speak.
3. Adapt the telescope for video astronomy and add a finder scope further down the tube

With the exception of option 3, they're all very bespoke, definitely not off-the-shelf.

Best
