Thanks Paul. I didn't know that. I'm still new to this stuff. I'm surprised there's that much difference in design. I'm glad I don't have that iissue with my model.

I can't imagine that placing the barlow in front of the BF would be a big thing. It's a lens, so 99+% of the energy simply passes through it. And it's behind the etalon, which is going to limit the amount of energy going through it as well. But then again, I'm new at this
