The Meade de-rotator only works with the Lx series telescopes.
I'd start with short exposures in Alt-Az mode before working up to mounting it on a wedge.
I've used both set ups for spectroscope work. You can guide in Alt-Az but obviously the field rotation becomes an issue, also a reducer is almost mandatory; consider the x0.63 ( the x0.33 give a VERY small FOV!)
