Estella Asked:

I want long range binocular, I know that it usually is directly proportional the the area of the lenses, but i eared that some electronically amplify the light from the source and by so can get a high zoom with great Propecia pill whithout prescription luminosity with a small collecting area...what would be the best? my budget is about 300$

Along with what Stargaze said, check the lenses. Look for a Bak4 lens. These are better quality than Bak7. Especially since you plan to spend such a high amount on binocs.

Lens coatings will play an important part as well. If you want to use them for astronomy, look for the "green" coated lenses. You will notice imediatly between those or the ruby coated ones.

If you go to a sporting goods store, and the person behind the counter looks confused if you ask about Bak4...leave.

Try going to a camera store that also sells binocs and telescopes. They can answer your questions based on what you want out of them.
