Are You A Star Gazer Or Astronomy Enthusiast looking to buy binoculars?
Do you enjoy night-sky watching? Invest in a pair of the best astronomy binoculars before spending big bucks on a high quality telescope.
Astronomy binocular reviews provide excellent views of star clusters, constellations, comets, planets and event the moon. They can show you more of the universe than you could ever image.
Benefits Of Astronomy Binoculars
There are several compelling reasons to buy astronomy binoculars before initially investing in a telescope. They are:
- Considerably less expensive
- Require no setup time, most telescopes require assembly or disassembly during observing sessions
- Much easier to use, provide right-side up images, making it easier to find objects
- Provide a much wider field of view
- More portable, can easily be take on vacation or trips
- Can actually be more effective than a telescope
- Valuable assets after the purchase of a telescope

10 Tips For Buying Astronomy Binoculars
1) Understand Magnification Levels
The larger the magnification level, the more difficult it is to maintain steadiness. For hand-held binoculars, the magnification level should be below 12x. Put binoculars on a tripod or mount for larger magnification levels. In other words, a 7x to 12x binocular will show you hundreds of open star clusters, nebulae and even some galaxies. For magnification over 12x, use a mount or tripod to see more details and discover more stars.
2) Understand Objective Lens Size
For astronomy binoculars, the recommendation is the bigger, the better. Larger objective lenses will reveal more stars, but at a price. Binoculars with Lenses greater than 60mm are called giant binoculars and should be placed on a tripod or mount.
3) Determine Hand-Held or Mounted Binocular Type
Decide whether you want the portability of hand-held or the additional functionality of mounted. There are trade-offs with hand-held versus mount. Hand-held are lighter and have a larger field of view, but provides less magnification. Big or giant binoculars will require a mount.
4) Choose Exit Pupil
Because our pupils dilate in the dark, binoculars used during the night require a larger exit pupil. Exit pupi of 5 or more should be used for astronomy.
5) Decide Between Porro or Roof Prism Design
Select porro-prism binoculars for astronomical use because they produce crisper images
6) Select Focus Type
Although both individual eyepiece and center focus are used with astronomy binoculars, individual eyepiece focus is easier to use since it requires no refocusing
7) Decide on Bak-4 or Bk-7 Prisms
Invest in BAK-4 (barium crown) glass to give brighter and sharper images
8) Elect Waterproofing
Spend the extra money and buy Waterproofing. Observing at night often exposes binoculars to moisture and dew, which will cause non-waterproof binoculars to leak.
9) Select Right Size Tripod
If you are buying mounted binoculars, understand tripod sizing. Compare the load capacity of the tripod as well as its actual weight to the size of the binoculars. For 80mm binoculars, the tripod should handle at least 121 pounds.
