Hi Fabio,
seems that you are a hardcore Zeiss fan
.
Many years ago, I had the predecessor Zeiss 7x50 BGA ( not T* ). As far as I can remember ( no guarantee for this statement ), stars in the center of the field were pin points, but the field of view was - typically for nearly every 7x50 - rather narrow ( 130m/1000m ). So at that time, I preferred the Zeiss Dialyt 7x42 BGAT* ( 150m/1000m ), especially for birdwatching ( my second hobby ) and I sold the 7x50 BGA.
As the Zeiss 7x50 BGAT* is far more expensive than the Fujinon or even the Nikon, it seems doubtful, whether it is worth the extra money. But it is more compact and a bit lighter than the Japanese competition.
Best wishes
Manfred
P.S.: At the moment my favorite for stargazing is the Zeiss Victory FL 7x42. I cannot see any spikes looking through this binocular. Maybe the spikes are so tiny, that they are not detectable, maybe my eyes are not good enough to see them. By the way, my most used telescope is a Takahashi Mewlon. This one shows spikes as well, caused by the spider holding the secondary.

Dear Manfred,
I don't know if the high cost of the Zeiss 7x50GA T* is proportionate to the optical quality; I'd like to understand this too, because the Fujinon 7x50 FMT-SX2 costs about 1/3...
Anyway, if I had sure the Zeiss is quite superior to the competitors (Fujinon and Nikon 7x50 Astroluxe), I'd be ready to spend the requested money.
I don't know the Fujinon 7x50, but I've got the 10x50 and this is of high quality; no doubt the 7x50 must be of the same quality...I think so...
The Zeiss has long eye-relief (18mm) and the Fujinon too (23mm declared, but 17mm usable); as far as I know, the Nikon has 15mm of eye-relief. I wear glasses due to my astigmatism, so long eye-relief is an important requisite; from this viewpoint I'd prefer Zeiss of Fujinon.
But what is the best among them?
Last June, I tested the Zeiss during daylight and I liked them, but was during daylight...
What is able to show the best pin point stars?
Manfred, I also have got the Mewlon, the 210 size. I've just ordered the Zeiss eyepiece: the 12,8mm of focal length for the Diascope, but equipped with the astro-adapter. I will let you know how it performs.
Bye,
fabio

Dear Fabio,
a few remarks about the best 7x50 for stargazing.
I think, you should nevertheless try the Nikon. Don´t forget, this binocular has only 50° field of view, so the eye relief is probably ok for you. I have a Swarovski 7x42 with only 13mm eye relief and I can see the whole field with my glasses on, because this binocular has only about 45° field. The larger the field, the longer must be the eye relief to see the entire field. You can try this with different types of eyepieces. For example, I can easily see ( without glasses ) the entire field ( only 30°! ) of my 4mm TMB Supermono, but a 4mm Plössl ( 50° ) or Erfle ( 65° ) would be completely unusable, although their eye relief is about the same.
There is a second reason to test the Nikon. It has an extra lens between the eyepiece and the prism system for better off-axis sharpness, so you can expect pinpoint stars nearly over the entire field. A long time ago, I read an English or American review about binoculars for astronomy, the winner was the Nikon SP, Zeiss and Fujinon were second.

Hi Fabio,
In my opinion, the Zeiss 7x50 is not superior to the Fujinon, only more compact. None of them is as good as the Fujinon FMTR 10x50, when it comes to star images near the edges of field.
I haven't seen the Nikon yet.
Cheers,
Holger

Hi Fabio,
I have both and tested them against each other. Just google for "zeiss 7x50 bgat" and the my test should come up as the first link.
I a nutshell, the Zeiss are better, but only marginally so. No reason to pay the premium, so stick w/ the Fujis. Also, the Fujis accept nebula filters which are quite useful.
Best regards,
Klaus

Zitat von fabietto:
Yes, but the difference is minute.
Zitat von fabietto:
I wear eyegalsses too (who doesn't need them at 7mm AP?). The ER is almost identical, maybe there is an edge for the Zeiss.
Also, in general, keep in mind that I tested the old version of the Fujis .....
Best regards,
Klaus
