Yes, Steve, I could actually get the binos to focus on my dob by using a barlow (but not the OCA), but the magnification was insane.
Where did you get the Burgess set (and how much did they cost)? I was looking at the Stellarvue binoviewers, which are meant to focus in refractors. (The actual base unit is the same, isn't it, from all these sources?)
Cheers,
Brian.
