Paul,
I am assuming you are talking about an SBIG unit ?
You already have the guide camera in the STL - you use that.
If you are doing NarrowBand and can't guide or correct due to faint stars then you could use a remote guide head after the AO but before the filter wheel, using an OAG body.
So you can do it either way.
Its really a question of back spacing, adapters, extra gear and budget !

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.

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.
