Help! New to this..
Hi there, I am looking for advice. What specifications would anyone
suggest for Binoculars capable of making sense of the stars? I would like to see more than I can with the naked eye... I live in the North of England. Not good conditions. I can't even make out the Milky Way! Thanks for reading. |

That is, bigger objective lenses gather more light that is then sent to your eyes which allow you to see fainter stars. The downside of this is that the bigger the objectives, the heavier the binos get, and your arms will get tired holding them. There are bino mounts available, though. Clear coatings. Do not fall for those "ruby red" binos. That red reflection is light that is NOT going through the binoculars, and thus, not to your eyes. Ideally, the anti-reflection coating should be invisible. The idea of the coating is to make light go through the binos and prevent light from reflecting off the lenses. Don't go for too much magnification. Since you're likely to be holding the binos by hand, the higher the magnification, the more pronounced your hand shaking will be in the images you view. Also, lower magnification let's you see more of the sky (wider field of view) and will also make the images brighter. Most astronomy is done at low powers. In case you didn't know, if you could see the entire Andromeda galaxy in the sky, it would appear bigger than two full Moons. Hope that helps.

On the subject of higher magnification,
I checked out (in succession) three pairs of 50 x 60 in a photographic shop whilst at Cairns, Queensland. They were Bushmaster brand, made in Australia I believe. All of them were badly collimated resulting in double images. Obviously high magnification increases collimation error. I have two pair 7 x 50 and 10 x 50. I'll stick to those. Minge.
