5mm-6mm EPs for binoviewer?

I've been enjoying my new Binomate and 100mm f/6 achromat for a couple of nights (complete review coming when I have a bit more time with it). I have a pair of 25mm Sirius Plossls and 10mm Antares Elites and they work quite well on the Binomate, giving 24x and 60x. Images merge easily and they're sharp. I wear glasses with the 25mm but not usually with the 10mm. I'm getting addicted to the two-eyed views.

A 2x Shorty Plus Barlow will not come to focus with either my 25mm or 10mm, so for higher power, I'd like to get a pair of mid-priced eyepieces about 5mm (120x) or 6mm (100x). I'm picky about sharpness.

Web articles indicate that a 6mm orthoscopic has somewhat more eye relief than a 5mm Elite or Plossl. Can anybody tell me about these eyepieces in a binoviewer? Is the eye relief a problem? How about merging the images with such short focal lengths?

Hi Tom,

I've posted a link to this write up several times before, but it is still worth a read as you consider the shorter fl eyepieces in your Bino. Skip the top section of this page and read the information that starts about half way down the page. Here's the link:
