possible issue with Vortex Vulture 8x56
Looking at both the eyepiece lenses, there seems to be a subtle difference in the color of the coatings reflected off of each lens. The right lens has a more green-yellow tint, and the left has a more blue green tint. Both of the Objective lenses are a nice identical even green. Should I be worried about this difference in the eyepiece lens tints? For the life of me, I can't see any differences looking through the binoculars, but what should I be looking for if this is a problem?
The second possible issue is potentially the focus mechanism. For focusing on most terrestrial objects the focusing is quite smooth and I have no problems. However, when focusing on very distant objects, say stars, I can keep adjusting the focus wheel for yet further and further distances beyond which even the most distant objects like stars become out of focus (like they were in the foreground). Shouldn't the maximal distant focus range be a little closer to maximally distant objects, like stars? Or is this just a binocular thing that I'm not aware of?
Thanks for your help!
No, don't worry about differences in coating colors at all. In fact, the apparent color can change on the same coating with the angle and intensity of light. Absolutely will have no effect on performance.
As far as having that much focus travel beyond infinity, yes, that's a bit unusual, though I don't see it as a deal breaker for an otherwise nice binocular. Manufacturers typically design a little extra focus travel beyond infinity to accommodate differences in vision from one user to the next, but that much travel is a bit atypical. I still wouldn't switch binoculars because of it, unless it really annoys you or handicaps you for your astronomy.
