This thread might be useful insofar as identifying wedge options

You will be restricted to well under 30seconds on alt-az with the focal length of your OTA, even with the reducer. If it was me, I'd be going the wedge option ASAP, and off-axis guiding will be an important part of the mix.
Actually, if it was me, I'd get a second, cheap set up for imaging with a shorter focal length at first. If you're thinking about dropping $1000+ on a wedge, think about spending that on a lighter Eq mount and a short refractor to get things dialled?
