Astronomy Binoculars On Sale

For astronomy, a 7x50 model may be fine for observing the moon. To see more detail on planets, you'll need a larger and more powerful objective such as an 8x56, 9x63, 12x50, 15x70, or 25-45x100 and so on. Of course, a tripod will be needed for the larger binoculars due to the size, weight and magnification. A binocular that has an exit pupil of 5mm or more makes an ideal binocular for astronomy observation.
