I am looking at obtaining an Adaptive Optics unit for my STL11K and have a few questions.

1. Do I need a guide camera for this unit? Images I have seen of the unit suggest not, but I would like that cleared up.

2. If no guide camera am I still guiding via the guide sensor in the camera?

3. Or is it better to have an OAG in the mix?

I sort of know the basic idea of how these units work but need to know exactly what is involved prior to purchase.
