The only commercial oag for the aol setup is a moag.
The only guide cameras you can use are sbig cameras with an i2c port or as rally says a remote guide head.
I was using a moag aol combo, but it chewed too much backfocus. Now I use the internal guide chip and a rotator. I don't do narrowband, but if it floats your boat, the internal guider ain't gunna be much chop.
