Bino viewing through a 6"

I went to a friend's to try out his linear binoviewers as well as his giant 25x100 binocular on a parallelogram mount. It was a clear night but the moon was 90% full.

We started with the linear binoviewers (orion premium) on the 6" newtonian.

• First with two Baader Mark IV zoom: I was unable to merge the images from both eyes, so very disappointing.
• Then with two SVBony UWA 68deg 20mm: that was much better, interestingly it felt better when looking at stars than when looking at the moon. Looking at open clusters, there was no noticeable loss of brightness compared to mono viewing, but the viewing was a lot more comfortable with both eyes, closely packed stars were maybe easier to separate even. 
• A great experience overall with the right eyepieces.

Then we switched to the 25x100 on a UBM parallelogram mount. 

• It was definitely easier to setup that my EZ Mount.
• The ability provided by the parallelogram to keep the direction when pushing the binoculars away or closer is great, also the mounted laser (with a switch on an extension cord is nice) helps with aiming.
• It moved around nicely (comparable to the EZ mount with the 12x70) and there was never a need to tighten any knobs.
• Once on target, the AFOV felt a bit smaller than the telescope with the binoviewers and the quality of view quality was lower, also things were also not as still.
• Finally, like with the EZ mount, one needs to get up, move the chair when moving to a different part of the sky.
• Overall, a superior experience to the EZ mount no doubt, but I think I will invest in binoviewers instead.
