Careful consideration needs to be made whether a new birder or one who has spent some time in the field and acquired some expertise. Most people, who think about buying a telescope, either go to a local department store or toy store and buy any telescope they have for sale.
First, determine just how and under what circumstances you will be using your new binoculars. Many night vision binoculars work similar to digital cameras, they have a built in flash. For astronomy use you will need at least 40mm aperture and preferably larger.
So if you have a pair of binoculars with 8x magnification, they should have an objective diameter of 40. So a pair of binoculars that has the number 7x30 stamped onto the casing is a binocular that will magnify any object to seven times its actual size, and has a lens size of 30mm. Compacts have objective lenses 25 mm or less.
By selecting binoculars that have a rugged construction, you are less likely to damage them through bumps or drops. When I finally got my first pair of binoculars just a couple of weeks ago, it was like Christmas again. The only negative review I have to offer that the lens caps are cheap and are nowhere near the quality of the rest of the binoculars.
Now it is time to get outside. A good warranty is your ticket to trouble free repair.
