Very interesting comment Andy. I use the WO 1.25 on my 60mm f/5.9 refractor, and the 24 Panoptic and all longer FL eyepieces vignette as decribed. I don't find it terribly annoying, but would consider a TV Everbrite diag if that means full light to the edge of the field and a crisp field stop. does the Everbrite achieve this?
