POWER or OBJECTIVE LENS, Which Matters The Most?

Power or magnification isn’t the only factor for best optimization in observation clarity.  It’s crucial with a decent magnification when it comes to low-light observing.  As for stargazers, you’ll go for a pair of 50 mm objective lenses, with a either 7x or 10x power for high mobility.  You always want a portable unit with sturdy and clear views yielded.

Low lighting shouldn't be confused with dark ambience.  Thus, stargazing doesn't need a night vision device or NV binoculars.  In astronomy observation,  the brightness of deeps-sky objects is known as low light in magnitude, not observer's environment.

From the above diagram, it’s easy to understand that the lower magnification the wider field of view it yields.  A balance device is up to resolve the target’s in better clarity.  Therefore, an excellent pair of binoculars in astronomy is required with high-end lenses coating as well as prism type.

When you look up to the night sky for your desired object, you want to observe it as much detail or beautiful as you could.  None is willing to observe with doubtful mind due to the poor light transmission by the low-quality coatings.

You Want A Performing Binoculars at All Time, Yet Lasts for Years, Don't You?

Is a pair of waterproof binoculars equivalent to marine binoculars?  Of course not, we know where the border lays.

Binoculars with gas-filled for waterproof and fogproof is essential for an astronomy enthusiast or bird watcher. Gas purged bins protect the device from moisture and fungus while the device working well in all weather, but not in the water.  Binoculars in the rains are fully different from being in the water!

Marine Binoculars is built to resist stiffer and rougher environment, and thus the special material and workmanship will apply to serve specific group of users, for example, fisherman, sailors and etc.
