Anyone got any ideas on the following? I was reading a recent debate on if small binoculars or monoculars where better of backpacking.one respondent claimed that only using one eye loses you 2 degrees of magnitude.no as I'm not an optician and don't really know how the human brain processes visual imput I can't say if this is true or false.from what this fellow is saying using a binocular over a monocular will gain you 2 magnitudes in visible light.it got me thinking about,if true,how this would work with telescope binoviewers? would a telescope with a binoviewer be able to see fainter objects than with a normal single eyepiece? unlike binoculars a binoviewer afixed telescope only has one light collector while a pair of binoculars has two. I may at some point try and test this theory as I have a pair of 8x25 binoculars and the monocular equivalent by the same manufacturer.to be honest I think it might be wrong as the brain merges the images but then they're factors like dominat eyes,etc.
