I used one in my C11, and achieved the best results with it. I was planning to get another one for use with the 8" RC.. When imaging with a longer focal length, I do prefer to guide at a similar length.. an OAG is the best way to achieve that, provided your guide camera is sensitive enough to pick up stars (your QHY5 should be fine!)
I had absolutely no issues with mine, worked a treat..
