As for FOV with your 1.25" nose piece I suspect narrow FOV eyepieces (Plossls) might be your best bet. If you have some in various magnifications, try them and see what works and double up on the ones that do.

That is how I did things when I used the WO with my C5 (I eventually went to a pair of 8mm eyepieces and no barlow or corrector).
On my C11, I use a power-x-switch diagonal and a pair of 20mm and a pair of 15mm eyepieces.

What I'm trying to do is use barlows instead of various EPs. The WO comes with two 20mm EPs, instead of getting two smaller EPs I thought a 3X barlow would work. I have the 1.6 that came with the bino unit and I have a 2x Celestron barlow. From what I've read, there are only a few choices of different EPs that work well with it. The 20mm seems optimal, but because of it's limited aperture (not sure what word to describe it) a larger EP would vignette. And smaller ones will quickly reach the magnification limit. So if barlows are not the way to go, what more powerful EPs can be used with it.

Shawn, yes I have and it works very well. Hence, my thinking that a 3X would also do well....
