A few initial thoughts Marclau:-
"
would these provide a great means for viewing planets, moon & nebulaes/galaxies??"
Well yes and no. You have fixed (and not very high) magnification so will get little detail on planets. At 25-28 magnification, it can be hard to locate items in the field of view - remember telescopes typically have a 6-8 mag finderscope to locate objects. You would not get the resolving power that a reasonable telescope can give you, probably even a 5" reflector. And you have the problem of mounting and, for straight through binoculars, the difficulty of getting to reasonable elevations. But you have compact convenience, the use of two eyes, a wide field of view to get the "big picture".
"No more viewing with one eye"
If you really want two eyes, a binoviewer might be a way to go. Pros - You get to use two eyes. Cons - $s, need pairs of eyepieces, may not come to focus without changes to the telescope, heavy so telescope may need changes to balance.
Why don't you start with a small pair of astronomical binoculars - around 10x50. You can get a reasonable pair under $100 from somewhere like www.aoe.com.au Then you can get an idea as to whether binoculars are what you really want for astronomical viewing. A pair like these will never be money wasted.
