The use of first surface diagonal mirrors will eliminate almost any possibility of reflections that prisms can create and also greatly reduce aberrations. These units have the spec's to outperform any bino in planetary and deepsky use. Try a set of my 2" 34mm or 2" 36mm 70 deg observatory series eyepieces for the ultimate DS view. Low mag correctors in the 1.3x, 1.5x and 1.8x range are available.  Add diopters for fine focusing.

*The Elite Binoviewer OCA has a CA of 29mm and the 1.3x will illuminate a F/S of 38mm 29 x 1.3=38mm FIA. This is what is needed of the support of the 36mm OB eyepieces.
