New scope from Zeiss... (1 Viewer)

In an on-line video previously sent to me by Zeiss and which I've unfortunately since deleted it was clearly stated that one of the rings is for focus and the other for zoom.

Well Peter thanks for that insight although that info was embargoed until tomorrow. However I can't imagine Zeiss will be too put out by this since tomorrow is only hours away.

So there we have it folks, its an objective-system zoom not a zoom eyepiece.

Which leads to the next questions... with the EP be fixed or not and what is the field stop diameter and thus field of view...

Hi Jo

Is it possible to fix the EP while you zoom magnification? If asked, I would have said 'no'.

It seems that it's the 85mm "Victory Harpia" on the photos posted by Troub,
so I guess the 95mm version will be even longer...perhaps close to 2 feet...:-O

"Harpia 85" is written on the body close to the EP-bayonet so I guess it can not be a ATX style construction,
but a more conventional body and eye-piece.

Ok, let me rephrase this... will the EP be removable or not... giving different magnification ranges....

See http://www.pt-ducks.com/cr-telescopes.htm for how BF member David Rodrigues uses a modified Nikon digiscoping adapter as a zoom unit with wide angle astro EPs...

Something similar in a nice package would be a birders wet dream... 82 deg AFOV plus across the whoe zoom range...

Joachim,

Just looking at the pictures, it looks a lot like the eyepiece would be exchangeable. No reason why it wouldn't be. So if, as now has been leaked in post #41, the zoom function is integrated into the objective and not the eyepiece, it would mean that the subjective FOV of the eyepiece would remain constant throughout the zoom range - which would be nice - and that it would be a simple matter to offer a range of good WA eyepieces to give people a choice of which zoom range they prefer. What we have seen is 23-70x in the 95 mm scope, but in principle there could be a 30-90x or a 40-120x WA option. Lower limit could go lower as well, but at some point the prism size would start limiting the subjective FOV.

Anyone here remember the ill-fated Zeiss Photoscope? Same principle - and excellent optics, I might add.

A shame the camera of that scope was outdated before it came onto the market.

BTW, here's a link to the old Photoscope: https://www.zeiss.de/sports-optics/...produktarchiv/victory-photoscope-spektiv.html
 
Almost certain, this will be my next spotting scope purchase. :t:
Glad I didn't buy the Swarovski or Kowa !
Look forward to when it becomes available.
 
It's closing time here in California, 10PM on the east coast, and tomorrow in the UK. Here is the link to the Harpia introduction video. https://www.youtube.com/watch?v=QtwxmnzsgC8&feature=youtu.be

Thanks!

Separate zoom ring on body.

DualSpeed focuser.

72 AFOV through the whole zoom range!

63-21 m/1000m FOV for 85mm model (22–65x mag).
59-19.5 m/1000m FOV for 95mm model (23-70x mag).

(what will the edge sharpness be? probably no flat field?)

Weight 1934/2078 grams (I guess that is excl. the eye piece that is 220 g).
Length 384/408 mm.
Close focus 3.5/4.5 meter.

3495/3995 € for the 85/95mm model (inc eye piece)
Made in Germany.

"Slim eye piece"
(Dobbler is poking on "large diameter" eye pieces as not being ergonomic)

Specs are on the link below, but nothing about ER of the eye piece.

So better FOV and larger zoom range as the ATX, that is not bad:
- ATX 95: 30-70x / 35-19 m/1000m
- Harpia 95: 23-70x / 58.8 – 19.5 m/1000m

Probably they will offer a higher mag eyepiece later on. Might also be an advantage compared to the ATX, probabaly easier to switche eyepieces in the field than to set up the ATX teleconverter.

Also interesting: "DualSpeed focus - Precise focussing with automatic switching between rapid and fine adjustment.". So they have integrated the dual speed in a single helix deal. Curious to hear how that works out.
 
Another link since the one already mentioned isn't working https://www.zeiss.com/sports-optics/en_us/nature/spotting-scopes/victory-harpia.html#features ...

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:D

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.

Just noticed that the eyepiece is 7.48mm https://www.zeiss.com/sports-optics/en_us/nature/spotting-scopes/victory-harpia.html#technical-data so the Docter will produce lower mags and might vignette. Higher power alternatives can easily be 1.25" astro eps (if these reach focus...), and you can have a look at http://www.pt-ducks.com/cr-telescopes.htm#Test%20of%205mm%20eyepieces - 5mm eps will result on 35-105x and 4.5mm eps will result on 39-116x!!!... Now using an Ethos 4.7mm (37-111x, as it's clones), it will be interesting to see how the 110º AFOV work at minimum magnification...;)
Now I understand why the video mention the scope was designed for high power use. I'm curious to see the image quality of these...o:D
