Yes, there is a perfect binocular. It's expensive enough to give you wonderful views of the night sky and cheap enough not to matter if it becomes damaged.

Indeed there is a perfect binocular: the Swarovski 10 x 50 EL Swarovision. Perfect edge sharpness, no chromatic abberation. Stars are pin point in this binocular. I have seen through many binoculars, but the only perfect binocular for nigt- and daytime use is the Swarovski 10 x 50 Swarovision.
I have bought this binocular. It's very expensive but worth every penny. It's simply the best binocular one can buy.

Decreasing levels of joy experienced when looking through binoculars coincided with a need to wear glasses to see the sharpest images.
Given the topography of my facial features, this at a stroke, savagely eliminated from the list of previously particularly desirable models,any and all that offer less than 16mm of effective eye - relief.
It's nine years ago this month since the situation first arose,and I must admit to previously never having given the matter a single moment's thought.
Although perfection probably exists only in the realm of fantasy and imagination, a major step towards it for me would be binoculars with eyepieces that are tailored / customized just as prescription eyeglasses are.
That way, I could at least approach reliving the wonderful experiences of yesteryear,able once more to see a full field of view,with eyes encapsulated by the eye cups, blocking stray light,without the discomfort and inconvenience of eyeglasses and their annoying reflections, able to enjoy astigmatism-free images of chosen scenery and objects.
If my glasses are tilted as little as 5 degrees from horizontal, everything I see turns into a blur, so contact lenses would need to somehow remain at a very specific fixed axis to successfully correct the kind of astigmatism from which I suffer.
Given that prescribed eyeglasses can be produced within hours of eye tests, for the price of meals for two in a very modest eating establishment,and the price of alpha roof prism binoculars,it perhaps one day may not be beyond the realms of practicality to have binoculars custom made ?

9x63 Orion Mini Giants - cost is reasonable, the weight and the magnification are both low enough to make this hand holdable for extended periods, great eye relief, no blackout issues, excellent light grasp, pretty good edge performance, and very sharp star images. If I have limited space and can only take one binocular with me, this is the one I always choose. For image quality I do prefer my 16x70 Fujinons, but the eye relief is horrible, they are also very bulky and are so heavy I can only use them on a tripod.

Kenny would the Tele Vue dioptrix help your condition?
Maybe there is a way to adapt them to your favourite binocular.

You would need to specify the application.
For astronomy, I would give top honors to the Nikon Prostar!

Bill,
I agree that the 7x50 Prostars are superb and I look for opportunities to use mine whenever the conditions are right for them. However, I find that their very low magnification the bright sky backrounds that you typically get with them (even at dark sky sites)limits their use value for astronomy.
For a hand hold-able binocular I usually recommend to people that they get either a quality 10x50 if they can handle its extra weight the increased jitteryness that accompanies using a higher power binocular or a 8x42 if they can't. At a dark sky site a well made 8x42 can perform very well and perhaps 8 times out of 10 I prefer the views they provide in comparison to the 7x50 Nikon Prostars.

Hi John:
First, I should say that I would prefer a 10x50 as well—for these parts. However, there are still places in the States where a low-power bino—especially one as good as the Prostar—can really be a life changer. For example: along lonely stretches of highway 2 in southern Iowa, where you can get “starburn” from the Milkyway at 2 a.m.
But, I recognize all is speculation; all is subjective. That’s why I rarely pop up in these discussions. This is an arena in which Einstein, Superman, or Christ would have his word doubted. And that, of course, is how it always will be . . . and should be. 
Cheers,
BillC

Hi
I had a pair fujinon 25x150ED very nice binoculars but they were not perfects, no chromatic aberration, but they were heavy (18 kilograms) and at the end of the field the stars were like comets, nothing bad, but this something I do not like. They have an exit pupil of 6 mm . Now I have the Docter Aspectem 40x80 ED which an exit pupil of 2mm. I am very satisfied with this binoculars they are almost perfects, from 0 to 5 I give a 4,9 in terrestrial obseravcion (observing a castle which is 7 kilometer far from my site, it looks like it was 2 metre from me). From 0 to 5, I give a 4,8 in night sky obseravcion just because they are not 45 degree, though for me that is not an issue; there are not distorsions neither chromatic aberration, it weight is 4,900 grams, you do not need a heavy tripod nor counterweights. Saturn was low over the horizon, it looked like I was observing with a very good apochromatic telescope but with the two open eyes. Searching open clusters globulars they are perfects. To my surprise I found the M31 galaxy low over the horizon of a big costal city full of light polution. (Alicante, Spain). Observeing darker areas it was very nice observe the Scorpium region and Sagiatario region.
Regards
Toni
