Harpia 95 vs. X95 - my biased contact

Finally did it http://www.pt-ducks.com/cr-telescope...Zeiss_Harpia95 - my thoughts about the Harpia with some speculation...

I would like to have store in Portugal as the one of BirdLife Sweden!

Thanks a lot, very interesting insights not only regarding the technology, but also regarding the difficulties of re-sighting banded birds!

You mentioned that you'd have preferred a straight version of the Harpia ... I presume that's due to the difficulties of (quick) target acquisition at the very high magnifications you're operating at?

Regards,

Henning

Hi Henning,

I'm glad you enjoyed.
No, besides the natural felling that is easier to find a bird with a straight scope, straight scopes are more practical for my birding because:
1 - I spend many hours in hides with high windows so with an angled scope I would had to stay up and not seated, and even in some hides, an angled scope had to be turned 90º for one side and I'm 178cm tall, so not too short...;
2- I do down-hill birding often also - one wetland have a birding point in a cliff, several tens of meters up from the surface – with an angled scope the neck would suffer. Angled scopes are better to look up, like raptors soaring.

After posting this thread I contacted Baader to ask if they had plans to do an adapter for using 1.25” astro eps with the Harpia. They told me that until now no one asked for such adapter… For those that don’t know, Baader produce such adapter for the Diascope that is much better and less expensive than the one produced by Zeiss. So those owners that are interested in increasing or reducing the magnifications of their Harpia, increasing or not AFOVs, should send an e-mail to Baader to ask for it – the more requests arrive to them,the more probable they will release it and sooner …

Ah, thanks for the detailed explanation - makes perfect sense!

(I did experiment with aiming devices on spotting scopes a bit, so I wondered whether they might be beneficial for your application as well.)

Hi David,
In comparison, have you tried to mount several extenders (Kowa can offer a 153 mag with 2 units. I do not know if it is possible to add several 1.7 extenders on ATX models). if yes, how is image quality in comparison to your systems you described?
Regards
Yves

Bonjour Yves,
It's possible to add sever extenders on the Swaro X but I never tried because I know it wouldn't be useful for my CR-birding use: - my X95 with the 1.7x extender result on a 51-122x zoom http://www.pt-ducks.com/cr-telescope..._cr-telescopes
If I would use a second extender, it would result on 87-208x that is too high for CR-birding. Probably interesting to look at the moon or bright planets...
As I mention at the upper link, the X95 has very high definition, extender included, and at the same magnifications has higher practical resolutions than my combos - producers design their scope systems pieces to work together - but my combos can reach higher mags, FOVs and AFOVs, colour fidelity, ...
The Harpia 95 potential possibility of receiving a binoviewer and maintaining the zooming capacity made me thinking of my bino-combos http://www.pt-ducks.com/cr-telescope...CR-binoviewing and yesterday I tested it with a pair of XW20 (70º) and at minimum magnification it has >28% of the X95*1,7extender and can go higher mags than the maximum mag of the X95*1,7extender!... However, as the plan is to best the BTX95, I already have solutions that allow much larger FOV of the BTX but still lower AFOV - I'm trying to reach a solution with larger FOV and AFOV that already managed but still need some special pieces...
Will see if Zeiss will make my search more difficult as Swaro did with the STX95, the 1.7 extender and the BTX...
