Hi,

Apart from transporting scope and tripod in a trolley or carrying the scope in a rucksack, I don't think there is any solution to the problem. I have done the latter only once for what was going...

Agree with OhWeh that the 510 would be ideal for the ATS 65 and I see that Berlebach have a dealer in Victoria.
However, it might be better to order directly as the ATS 65 is very tail-heavy and...

John,

I was out yesterday with a group of birders, one of whom had an 8x40 Leitz Trinovid. I folded down the eyecups and tried it with my glasses on, but could detect no change in eye relief over...

Thanks, John. I get it now.
The eye relief would probably vary according to focus setting - decreasing towards infinity?

Nick,

I presume you tested the Swaro with the 25x-50x zoom and the Kowa with the 25x-60x wide angle zoom (TE-11WZ), or was it the old 20x-60x zoom?
I have both the Kowa 883 and a Swaro ATM 65HD...

I don't know about the AT 80 and can find no serial no. on my 30x W eyepiece.
The scope serial no is indeed inside the bayonet mount.

It takes two or three seconds to secure the binocular to the Leica adapter, probably quicker than mounting the adapter on the monopod/tripod.
