RCX AP Reducer + Required Adapters

A frequent question is which reducer will work with the flat field of the RCX (this also applies to the R scope). An excellent match is the one from Astro Physics, but you'll need the various adapters listed below.
One advantage of the AP adapter is that it opens up the 1.5" light path of the standard Meade one, to 2.7" (an alternative would be to buy an EyeOpener). This is important for both visual and imaging work. For visual you'll get a noticeably brighter views and for imaging you'll be able to fill much larger CCD chips with less vignetting.
Note the use of an adaptive optics unit in my rig. This gives amazing results with a standard RCX mount. I can easily get pin sharp stars of 30 minute duration using one of these with a RCX.
You should also be aware that this setup just swings through the fork mount with a couple of inches to spare.
