The OCS uses bright retaining rings for the lenses causing reflections especially in the focal reducer.
It claims the highest clear aperture yet vignettes with the Pan 24's
Bright stars or planets cause reflections from my eyes back into the bino and the bino combines the reflections - this may be a common problem with all binoviewers...
Most recently I have discovered that my new Denk is out of collimation without dropping it or even shaking it. It does not hold collimation and I do not know what is worse - not collimated properly from factory or loosing collimation in use. The unit is only few months old.
The eyepiece locking mechanism is crude and flimsy (but it works).
That is all for now...
I use it on 10" SCT with the 1 /1/4" OCS.

The Big easy performs at it's optimal with Denk eyepieces. I'm not surprised that the Pan 24mm vignet a little. This is not a problem with the binoviewer, in fact if you were to use the pan 24mm in another binoviewer system they would vignet more, For this reason I always recommend Denk 21mm for the Denk binoviewer. The Denk Binoviewers has a larger clear aperture which will give you a lower power and wider angle view then what can be achieved with any other binoviewer with out vigentting, This plus the Big easy package works on just about any telescope and has better multi-coatings providing better contrast is what sets the big easy apart from other binoviewers.
The eyepiece locking mechanism is designed to lock the eyepiece in the centre of the barrel, binoviewers that use set screws on the side push the eyepiece to the side of the barrel, and there for they are not centre, merging would be a lot harder. In my experience I have found them to work better than the other alternatives.
