Binoculars are a very useful tool for astronomical observation.  You can use it to watch a football game, a concert or birds in the sky.  You can also view the Milky Way two million light-years away, craters on the moon, several moons around Jupiter, galaxies, and nebulae.  

But if you learn to use binoculars, don’t forget to maintain them, or your binoculars will soon get damaged, and you don’t want to spend more money on new binoculars.  Next, we’ll learn how to store and maintain binoculars.

How do I store and maintain binoculars?

(1) How to maintain binoculars?  

To maintain the binoculars, first, cover the eyepiece and objective caps when the binoculars are not in use, or store them in the backpack and case that come standard with the binoculars.  Binoculars with built-in batteries should be removed when not in use for a long time.  Telescopes need to be kept dry.  Moisture is dangerous because it can affect optical elements and cause rust.  Make sure the telescope is stored in a dry place and check for dew before packing.  

If the telescope does get damp, it’s best to leave it uncovered for a few hours and then let it dry.  This prevents water from oxidizing delicate areas such as screws or leaving watermarks on the lens.  

If the lens of the telescope is stained with dirt, gently wipe it with a professional cloth.  To avoid scratching the mirror.  Or blow the dust off your lenses with an ear ball.  

If you need to clean the mirror, the application of cotton station a little superior pure anhydrous ethanol, from the center of the mirror along a direction to wipe the edge of the mirror.  And constantly change the absorbent cotton ball until wiped clean.  Be careful when cleaning your lenses and pay special attention to the optics.  Clean lenses only when visibility is affected, otherwise damage may be caused.  

(2) How to store binoculars?  

To store binoculars, the first thing to know is that water can be dangerous for the telescope, so don’t put it in a damp place.  Be careful if you store them in basements, as these areas are not well ventilated.  You can look for dry, dust-free areas in your residence with stable temperatures and easy access.  An indoor cabinet is probably the best place to put a telescope.  Many of them keep cool temperatures, allow air to circulate, and are protected from moisture.  

No matter where you place your telescope, you should take some precautions.  First, always cover the lens.  All LIDS need to be replaced before storage to prevent damage.  If you’re moving a telescope from a warm room to a cold backyard, it’s best to let the telescope sit for a while to reach a temperature balance with its surroundings.  The larger the mirror on the telescope, the longer it takes to cool down.  

While sudden heat changes do not affect the performance of the telescope itself, they make it more difficult to see through the instrument because heat radiates from the telescope and distorts the surrounding air.  Finally, be sure to keep the telescope in an accessible place.  You need to be able to use it, and you don’t want to risk bumps while maneuvering.  

FAQ:

How do you store binoculars?

Avoid keeping binoculars in high humidity, high temperature, or dusty areas. It is best to keep them in a plastic bag or an airtight container with a desiccant. If this is not possible, do not store the binoculars in the supplied case, because they are easily affected by moisture.

Is it bad for binoculars to get cold?

Most binoculars do well in moderately cold conditions, but extreme cold conditions require a pair of opticals that are rated for use in extreme cold. So it’s wise to seek out binoculars that have an anti-fog feature to keep the lenses clear at all times.

How do I clean the inside of my binoculars?

Hold the binoculars upside down and use a lens cleaning pen’s bristles to loosen any light material, then use some canned air to carefully blow off the loosened dirt. If using canned air, ensure the product provides short bursts of air and not use it too close as it can frost up the lens.

What is the best way to clean binoculars?

To clean your lenses, first, brush or blow away the loose dirt with a soft camel hair brush or compressed air. Then lightly spray the lens cloth (never spray the binoculars) with a cleaning solution and gently clean the lenses.

How do you dry binoculars?

Leave the binoculars in a warm dry place for several days. Most binoculars are not airtight, so any moisture inside the binoculars should evaporate into the drier air outside.
