Although monoculars are a small-size version of the binocular, some models have an ultra-compact design. Having said that, if I were to go ahead to purchase a leica, swapping between them simultaneously for viewing could potentially create some viewing confusion? If oberwerk chart informs that is 90% of objective area, the count should be square root of (60 * 60 * 0,,9) = 56,9, but if them say is 90% of their objective size, the count should be 60 * 0,9 = 54. Right now, I'm strongly looking at the Nikon Action Extreme 12x50s since they have everything I was looking for in an upgrade over my Oberwerk 12x60 LW.

THE PERFECT KIT FOR OUTDOOR ENTHUSIASTS: Our monocular telescope is lightweight and compact, able to easily fit into pockets and backpacks. I assume it is a reduction in "real" diameter, with the objective stopped-down in some way by internal baffles, but I see that the quoted exit pupils are derived from the full aperture, not a stopped-down one.

The two issues with them that make them not so good for astronomy use are 1) They show chromatic aberration and things like Jupiter and the Moon and 2) Their central focus is way too easy to move.There’s also a thread for attaching a L-shaped adaptor just in case you want to attach these binoculars to a tripod.

So with the Diamondback’s too easy center focus knob and chromatic aberration, I’d have to believe the Celestron 12x50 ED would be a better choice. delivers more light to the view, reduces chromatic aberration and ghost images, give you a clear, bright, and more colourful vision up to 1,000 yards.

It's a toss-up at this point if it will be worth it to get a "smaller" pair of binoculars since I am an aperture junkie first and foremost.But from shining a laser through the eyepiece of them and measuring how the disk of light that comes out the aperture I get 54mm. The end of the barrels where the objective lenses are ser reflect this difference by about the same amount.
