I had the occasion to compare the btx 85 and ATX side by side this very weekend with sunny weather and wanted to cheque the potential difference in contrast or brightness and I could not find any , nor in shadow , nor in sunny condition
Highly impressed with BTX performance
A few weeks ago I looked through a BTX with 65 objective , and optically just fine, but balance is not so well

I have the BTX 85 and it is every bit as sharp as my former Leica 65 25-50x. The viewing experience is not comparable though. Being able to use two eyes, the view is highly enjoyable and relaxing, like binoculars, but that's obvious. Also, it seems that there is a higher 'apparent magnification'; the brain distinguishes more details with two eyes. 30x seems like watching at 40x using only one eye. Very satisfied with this amazing scope!

Thanks for sharing that!
I would definitely try another unit before coming to a difinitive conclusion, I love the concept and viewing comfort was really top notch!

I like the idea of the BTX, hell of a price! But I don't think it would work for me.. i tend to sit down, and scan, I don't know, 50 degrees either side of straight ahead. With one eye, I can look at an angle into the scope.
I'm pretty sure I'd need an extendable, extremely flexible neck to continue to look with both eyes.

it's as if a typical tripod is not designed for the BTX.. you need the pivot point to be where your spine is, if that makes sense. (or sit with tripod on a rotating base!)

Might be late here. I just got the BTX with 1.7x extender. Tried it on the 95mm, no loss of details. Best balance with BR balance rail and PTH tripod head which is similar with the gimbal head.

I usually do not extend the eyecup to get wider FOV and with the indispensable built in forehead rest, as it makes viewing for longer period comfortable hahaha

Will report soon after using it in the rainforest next after my birding tours.
