Hi John,
Nows the chance to make Flash an offer he can't refuse....The 28's in a binoviewer, which is basically a two eyed barlow, do have a bit long ER and the rubber eye guards will get in the way of the view big time. I use a towel over my head, nice when it's cold and it's a bit like staring at the shapes that turn into a 3D picture...everything else melts away and your left with what your looking at....

The 28's become the ideal 14mm eyepiece (mono view) which in my scope is the best FL for DSO's.
Flash how are the Denks compared to the WO bino's?
