Giant Binoculars Use, Mounting, and Buying Guide

What are Giant Binoculars

Giant binoculars are the types of binoculars that have large objective lenses to see objects far away. They have higher magnification than regular binoculars and are designed for astronomical observation, birdwatching, and other long-range viewing applications that require high resolution and brightness.

Giant binoculars typically have objective lenses that are 70mm or larger in diameter, which allows them to gather more light than regular binoculars. The increased light-gathering capability, combined with high-quality optics and coatings, results in brighter, sharper, and more detailed images.

In addition to larger objective lenses, giant binoculars also have higher magnification than regular binoculars. Magnification is usually indicated by a number followed by an “x”, such as 20x or 25x. This number refers to how many times closer the image appears than it would to the naked eye. Higher magnification can provide more detailed views, but can also make it harder to stabilize the image, especially when viewing from a handheld.

Giant binoculars as the name represents are bulky and heavy as compared to regular ones. Their bulky size makes them difficult to carry around. They also require a sturdy tripod or mount to achieve steady views. However, their larger objective lenses and higher magnification can make them ideal for certain types of observation, such as observing deep-sky objects, distant landscapes, or wildlife from a stationary location.

How to use Giant binoculars

Giant binoculars are a powerful optical tool that can be used for a variety of applications, including astronomy, birdwatching, and nature observation. Here are some detailed steps on how to use giant binoculars effectively:

  1. Choose the right binoculars: Select the binoculars that suit your purpose. For astronomy, binoculars with larger objective lenses are ideal. However, for bird watching or other nature observation, you may want compact or mid-size binoculars that are easy to carry and have a wider field of view.
  2. Adjust the Interpupillary Distance: Set the interpupillary distance of the binoculars to match the distance between your eyes. You can do this by adjusting the distance between the eyepieces until you see a single circular image.
  3. Adjust the Focus: Use the central focus knob to adjust the focus of the binoculars. Look at a distant object, and turn the knob until the image becomes clear and sharp.
  4. Adjust the Diopter: Most binoculars have a diopter adjustment to compensate for differences in the visual acuity of your eyes. Adjust the diopter until the image in both barrels is sharp.
  5. Use a Tripod: To avoid shaky images, especially when using large binoculars, use a tripod or other stabilizing device to keep the binoculars steady.
  6. Use Accessories: Attach filters, eyepieces, or adapters to enhance your viewing experience. For example, you can use a tripod adapter to attach the binoculars to a tripod or a smartphone adapter to take pictures or record videos.
  7. Practice: Practice using your binoculars by observing objects at varying distances and lighting conditions. The more you use them, the more comfortable you will become with the settings and features.

How to mount Giant Binoculars

Mounting giant binoculars require a few steps to ensure stability and optimal viewing experience. Here is a detailed guide on how to mount giant binoculars:

Materials needed:

  • Giant binoculars
  • Binocular mount (equatorial or alt-azimuth)
  • Tripod
  • Counterweights (if using an equatorial mount)
  • Allen wrench (if required by the mount)


  1. Set up the tripod: Choose a stable and level surface and extend the legs of the tripod to the desired height. Attach the mount to the tripod head according to the manufacturer’s instructions.
  2. Attach the binoculars to the mount: Most mounts have a quick-release plate that attaches to the bottom of the binoculars. Attach the plate to the binoculars using the provided screw or knob.
  3. Balance the binoculars: If you are using an equatorial mount, you will need to balance the binoculars by adjusting the counterweights. This ensures that the binoculars remain steady and do not tip over when moved. Use the mount’s manual to determine the correct balance point.
  4. Align the mount: For an equatorial mount, align it with the North Star or other celestial object. For an alt-azimuth mount, align it with a nearby object or landmark.
  5. Adjust the binoculars: Use the mount’s controls to move the binoculars to your desired viewing position. Adjust the focus and diopter settings for each eyepiece if necessary.
  6. Secure the binoculars: Once you have found the desired viewing position, use the mount’s locking mechanism or knobs to secure the binoculars in place.
  7. Enjoy the view: You are now ready to enjoy the view through your giant binoculars!

Remember to always follow the manufacturer’s instructions for both the binoculars and the mount, and to take caution when adjusting the binoculars to prevent damage or injury.

Buying Guide of Giant Binoculars

Giant binoculars are designed for stargazing, bird watching, and other outdoor activities that require a larger aperture and magnification power than traditional binoculars. These binoculars can range in size from 70mm to 100mm or larger, and they offer a wider field of view and brighter images than smaller binoculars. If you’re considering purchasing a pair of giant binoculars, here is a buying guide to help you choose the best one for your needs:

  1. Magnification and Objective Lens Size: The magnification power of giant binoculars usually ranges from 15x to 25x. However, a high magnification power can lead to a shaky image, so consider a lower magnification if you don’t have a stable mount to use. The objective lens size, which is the diameter of the front lens, determines the amount of light that enters the binoculars. The larger the objective lens size, the brighter the image. Look for a balance between the magnification and objective lens size that suits your intended use.
  2. Optical Quality: The optical quality of binoculars is determined by factors such as the quality of the lenses, the coating on the lenses, and the alignment of the lenses. Look for binoculars with high-quality lenses, such as ED (extra-low dispersion) or fluorite lenses, which minimize chromatic aberration and produce sharper, clearer images. Also, look for binoculars with multi-coated or fully-coated lenses, which reduce glare and improve light transmission. Finally, ensure that the binoculars are aligned properly, and the two barrels converge perfectly to form a single image.
  3. Comfort and Ergonomics: Giant binoculars can be heavy and difficult to hold steady, so look for models with a comfortable grip, and that is ergonomically designed. The binoculars should have a rubber coating to prevent slippage and to make them easier to hold for extended periods. Also, consider the weight and size of the binoculars, as you will be carrying them around with you.
  4. Durability and Waterproofing: Giant binoculars are an investment, so you want to make sure they last. Look for models that are made of durable materials, such as aluminum or magnesium, and that has a rubberized coating to protect them from bumps and scratches. Also, look for binoculars that are waterproof and fog-proof, so you can use them in all weather conditions.
  5. Accessories: Consider what accessories come with the binoculars, such as a carrying case, lens covers, and a tripod adapter. A carrying case will help protect your binoculars when you’re not using them, and lens covers will keep the lenses clean and free from scratches. A tripod adapter will allow you to mount the binoculars on a stable tripod, which is essential for stargazing.

In conclusion, when choosing giant binoculars, it’s important to consider the magnification and objective lens size, the optical quality, the comfort and ergonomics, the durability and waterproofing, and the accessories. By taking these factors into account, you’ll be able to find the perfect pair of binoculars for your needs.
