Basically a lens that 'reduces' the focal length of your scope, making imaging more manageable, and gives you a wider view as well. It also changes the size of coverage on your CCD.
For example a 6.3 reducer reduces your scope to 1280mm from around 2000mm (you have the nexstar 8" I think??) and gives much brighter images as well.
There is a nice layman's style review here:

you can often get them second hand, Meade make one as well.
