I think the cheapest and easiest option might be to fit a 2-inch "visual back" to the rear of the scope. Bintel sell for $39 and typically stock these.

Bintel SCT - 2" adapter
This adapter threads onto the visual back of Celestron or Meade Schmidt Cassegrain telescopes allowing the use of standard 2" accessories. Uses brass clamping ring to hold your equipment securely but gently. No more gouged chrome barrels from overly eager visitors twisting your diagonal to get a better view. Also allows 2" accessories to be used directly behind Celestron and Meade focal reducers.
Length: 45mm
