Binoviewing in small refractors

I have been thinking of getting a Sky90II and wondering how well it works with a binoviewer? I currently use a binoviewer in a TV-76 for high power viewing with a TV barlow in front of the binoviewer and supplied corrector. I can't achieve focus with my TV-76 and the 1.6x corrector only so am limited to binoviewing at high power which is great for the moon and planets. I have read that some don't like to use a binoviewer in smaller scopes on deep sky objects because the light loss through a binoviewer hampers a small scope more than a big one. Has anyone compared the views at low power through a small refractor and binoviewer to single eyepiece viewing and preferred the binoviewer? Thanks.

Dave,

RE your TV-76 no achieving low powers: Have you talked with Mr. Siebert about his low power correctors and adapters. He might be able to help you.

Personally, I have used binoviewers with a Stellarvue 85mm f8.5 (I think). It has a nice JMI focuser that holds the 2" diagonal, bino, EPs, corrector at any angle. Watch out for cheap focusers.
