Good for whatever you want to use it!

Iíve been postponing this review for some time, but now I finally got the time to write. I bought these binoculars as a complementary equipment for my telescope; so, having good quality was a must. If you are planning to use it for astronomy and you donít mind using a tripod, then you should go for a 10x50; but if you are going to hold it in your ands only, then the 7x50 is the best option, because the trembling of your hands will bother you a lot when observing stars on a 10x50.
Regarding the ďHDĒ, this binoculars is a truly FMC and it does have more transmissibility than most binoculars. That becomes clear when you use it for terrestrial observations: all the colours are equilibrated by the coating and the extra transmissibility gives stunning views with vivid and bright colours. If you already have binoculars (with lower quality) and observe with both, youíll think that the image of the low cost binoculars is kind of whitened, but this is just a matter of transmissibility. The same effect can be observed when you use your binoculars through a glass window (dam 80% of transmissibilityÖ), youíll immediately notice the loss in quality. For astronomy, the extra transmissibility comes in form of more contrast.
About the flat field, the stars look like dots through the whole field of view, but as expected, the eyepiece focus cannot cover the whole field (Due to the 7.5 degrees angle of view, which is too large.); So, my tip is to focus on an object or star at 70% of the radius of the field of view (imagining it as a circle), this will keep objects near the centre and near the edges sharp. People who use it only for terrestrial observation probably wonít notice this kind of detail.
So far, I havenít had any problem with fog on the lenses, this is one of the advantages of a nitrogen sealed binoculars. I couldnít explore the full potential of this binoculars for astronomy yet because Iím currently living in a town with too much light pollution, and it will take me some time before I can travel to somewhere with a clear sky. Nevertheless, I could observe many details on the Moon surface (with almost no chromatic aberration, by the way) and the four Galilean Moons of Jupiter (this requires good weather, because the magnification is just 7x). And just for those who still expect an expensive binoculars to have a weak body, this one has a rigid shockproof metal body all covered in rubber, it also has a firm grip and it is not too heavy. It also takes some time to get used to the focusing system that requires to adjust the two eyepieces, and I still prefer the central wheel to adjust the focus, but I believe that the independent focus make it easier to seal the binoculars.
If you are planning to buy a good equipment, donít be afraid of getting an Apollo, itís a safe investment and itís going to last a life if you take care of it. The decision to make is just about going 7x50 or 10x50; and as I said before: Astronomy using hands, go 7x50; Astronomy with tripod, go 10x50; if you use mostly for terrestrial observation, go for the 10x50. I hope it helps, Clear Skies!
