Choosing the Best 10×50 Binoculars for Astronomy and Birding

Let’s know take a look at some of the important factors you should consider when shopping for the best 10×50 binoculars for astronomy and birding.

  • Lens Coating

The quality of images that the binoculars provide can either make or break your viewing experience. Good quality images let you see every single detail of the birds and celestial bodies. Go for a pair that features fully-coated or multi-coated lenses. They facilitate maximum light transmission for bright and clear image production.

  • Eye Relief

Eye relief is the maximum distance between your eye and the binocular’s focal point. Eye relief is very important if you put on eyeglasses. Luckily, most binoculars have adjustable eyecup to accommodate different users, with or without eyeglasses. Go for a model that offers more than 16mm eye relief so you’ll enjoy comfortable viewing even with your glasses on.

If you are going to be using the binoculars outdoors, make sure that they are impact resistant and have scratch resistant lenses. They should also have a rubber armor for comfortable handling and be fully waterproof and fog proof.

  • Field of View

Field of view is the area of view that you can see without moving your binoculars around. Binoculars with a wider field of view are the best for astronomy and bird watching. They provide easy target identification and help you monitor moving targets smoothly. For 10×50 binoculars, 6 to 8 degrees field of view will be sufficient.

  • Weight
