This is your first stop for a comprehensive explanation of Binocular Summation, how binoculars, telescopes and telescope/Binoviewers all compare and the benefits that can be derived from each.
Binocular Vision Summation
This comprehensive thread includes a compilation of all I have written on Binocular Summation. In addition several noteworthy posts by other members add some imporant information on vision.

Older threads that helped generate some of the information that eventually got included above.

The question gets asked, "What scope would provide the equivalent of the view thru a given size binocular?" You will find the answers here. Along with that you will find some links to some great information on the internet that will help you understand the concept of Binocular Summation. Also see the thread here at the top of the binocular forum that provides links to internet articles for more links to info on binocular summation.

Binocular Summation - Aperture Equivalency
This thread discusses what equivalent aperture would be needed in a mono view scope to produce the same amount of light and contrast as a binocular.


Binocular vs Binoviewer
in this thread the comparison takes a twist. Comparing to a binoviewer, you need to account for beam splitting and then the resultant binocular summation in the binoviewer.

This new thread Jan 2007, gives data collected from three different models binoviewers and shows how clear aperture restricts field of view. A summary is given for lowest power acceptable field of view for binoviewers and then that is also give as a binocular equivalent.
