How to Use a Monocular Telescope

Telephone lenses are one of the most excellent tools in photography today. Whether you are a beginner or an experienced photographer, this tool can help you capture stunning pictures around you. When you are always traveling around, hiking or canoeing, you are likely to have a moment that you want to bring the world around you closer.

This article will introduce one piece of equipment that can be either used as a mobile camera lens or telescope – a Monocular Telescope. Let’s take a look!

What is a monocular telescope?

A monocular is a modified refracting telescope used to magnify distant objects. The magnified process can be done by passing through a series of lenses, such as prisms. The modern monocular telescopes usually use prisms instead of relay lenses, ensuring an erect image, resulting in a lightweight and compact telescope.

The main difference between monocular and binocular is volume and weight. Since they have similar optical properties, the volume and weight of a monocular are less than half of a pair of binoculars. Therefore, it makes a monocular easier to carry and also proportionally less expensive.

A monocular is essentially a compact telescope that can be used for bird-watching, archery, viewing distant scenery, hunting, etc. The better thing is that many monocular telescopes can connect with a phone, enabling you to view distant sceneries and take pictures of them.

Tricks & Tips to Use a Monocular

When you are holding a monocular telescope up to your eye make sure you keep a firm and proper grip on it. You will track and localize your target through the lens.

1. Use your dominant eye

If you have impaired vision, it is critical to use the eye with the best eyesight. Make sure you hold the monocular with the hand on the same side as the dominant eye.

If you are wearing glasses, when using a monocular, let it press lightly against your glasses. Try to fold down the rubber end to support your field of view. In addition, it is best for people who are wearing glasses to choose the monocular that offers at least 14mm of eye relief. In other words, it means you can hold the monocular at least 14mm away from your eye and still clearly see through it.

2. Hold the monocular and adjust focus

Griping the barrel close to the ocular lens while you hold the monocular up to your eye. The lens should close to your eye as much as possible without actually touching it. In the meantime, keep your other eye closed to maintain focus and use your forefinger to stabilized the monocular.

In terms of adjusting focus, different types of monocular have different adjust ways. Some of them only require one finger to rotate a ridged dial, but others require both hands.

3. Tracing and tracking with the monocular

Face the target: Every time you use your monocular, you should locate the objects you want to view. Keeping eyes on the objects first can help you locate them more precisely and quickly. If you lose the objects on monocular vision, try to open another eye to locate the position better.

Track the target: Sometimes, you will need to follow the objects with your sight slowly if you observe a moving target. When using the monocular, try to avoid sudden movement since it will lose track of your target.

Refocus the moving target: If your target moves closer or further away, you will need to readjust monocular focus. Readjustment will help you keep the target view clear after it moves.

4. Hold your position

During the usage of a monocular telescope, your magnified vision will cause you to ignore the objects around you or near you. Therefore, it is inappropriate to move with the monocular pressed against your eye, which might cause you injuries. Remember always to turn your body towards the target, but don’t walk, run, drive, or any dangerous movement.
