Unfortunately it seems that there is no straight view versions :C...
My astro combo concept that Joachim mentioned http://www.pt-ducks.com/cr-telescopes.htm#Test%20of%2082%C2%BA,%20100%C2%BA%20and%20102%C2%BA%20AFOV%20zooms was well observed by Zeiss and I'm glad I gave ideas to them - they probably didn't needed these but I made it first and with 3.5x zoom ratio...:king: Future owners of these models will see what I have be seeing for some years but even with wider AFOVs...
So it will be possible to use higher mags than 70x by replacing the eyepiece. Don't know if the system allows the use of 2" astro eyepieces but at least 1.25" will be possible and I'm remembering the Docter 12.5mm with 84-88º AFOV...
A Zeiss ep with higher magnifications can have wider AFOV...o
Don't know if will be possible to Zeiss to develop a binoviewer to these models but, if so, it will zoom and that would be an advantage compared to the BTX.
The exit pupil is given as 2.50 at 23x or 22x.
What does this mean?
The filter thread of the 95mm aperture is M95 x 1.00. Does it slightly cut down the aperture?
...
Zeiss could even make a zoom EP and then you would have the first zoom-zoom scope...would it be weird enough for you? :-O

Seems that the new model Harpia is amazing regarding the optical qualities, but the pricing is ridiculous. It will be a good scope for professional purposes, but somewhere unreachable for regular birders. I imagine that does we see as many Harpias as Nikon EDG scopes on the field? Hahahaha.8-P
... I had a play around with it yesterday on the stand with the experts and its a great piece of kit.
...
I suspect the Harpia eyepiece may be designed to work properly only when it is combined with the zoom elements in the Harpia scope body, and that other universal type eyepieces cannot be substituted.

One more question for Troubador or any other BF members at Birdfair. Are the odd exit pupil specs simply a mistake?
I ask because a possible, though quite bizarre, explanation for the 2.5mm exit pupil at 23x occurred to me. Could the "objective" zoom system cause increasing aperture vignetting at low magnifications so that the clear aperture is reduced to 57.5mm at 23x? Say it ain't so!
