Hi OneofOne
I would say that once you have used a 3.3 red. with your SCT you'll never go back
I use one with my DSI pro & LX90 (2500 mm F/L) and can fit things like the swan neb in one frame whereas without it seemed like less than half,or 80-90% of M42 with, or just the trapezium & surrounds without.
it would seem that the DSI has to work a lot harder without it & it's harder to focus
It's not really so useful if you are taking shots of planets where you want the magnification
the Meade 3.3 comes with fittings so that 3 different F/L's can be used, the fittings mate with the DSI & require aa SCT/2" adapter if you have a 2" focuser
Good luck
Bryan
