Before you dismiss this as crazy and nuts I need you to know that I am perfectly serious (No he's not, don't listen to him!).
Other than my binoculars, I will never purchased or use a bino-viewer. Way to costly. Quality bino-viewer, expensive! Matching pairs of eyepieces, way to expensive. Extra-large Pelican case to store all of the afore-mentioned pairs of eyepieces, very expensive! Not to mention that all that extra mass will make your scope very back-heavy.
Also, consider this...every Cyclops that I have ever seen had one very big eye. This means you will be able to have a telescope/eyepiece system that will produce a really LARGE exit pupil.
For all of you who use or present very compelling arguments for wearing an eyepatch, that point then because Mute.
I'm sure that any really skilled plastic surgeon should have no problem with a challenging rhinoplasty procedure as well as converting you to a single eye. Though you many need a neurosurgeon to convert your brain and the optical nerve and anything else that would require conversion to single eye viewing.
Oh sure, it may take a while to get used to looking like one of the one-eyed Minions, but consider all the pros. Prescription glasses would be cheaper, requiring only one lens. Choosing a costume for halloween would be a No-brainer. Also, if an actuall tribe of cyclops were ever discovered, you'd have no trouble fitting in.
So, say NO to binoviewing and lets all celebrate single-eyed telescope viewing by converting to cyclo-amateurs.
