BINOVIEWER QUESTION

Does any binoviewer show a corrected
erect image, I want to use one for
terrestial viewing,any info or opinions
will be greatly appreciated,
thanks in advance,
bob

Ours and most other non-mirror type binoviewers transmit the focal plane created by an objective and other components of an optical train in the same orientation that is seen in a single eyepiece.

If you see an upside down (inverted) image in a single eyepiece view, it will be the same in the binoviewer eyepieces. For daytime viewing through telscopes that produce an inverted image, an erecting prism diagonal must be employed. This will allow you to view birds, trees etc. in their proper orintation through a single eyepiece and through most Binoviewers.
