Terrestrial Telescope Buyer’s Guide

A terrestrial telescope is a device that allows you to observe terrestrial objects with ease without inverting the image. It provides you a clear, accurate image without any distortions and is the best way to observe terrestrial objects during the day. This is a specific type of telescope so when you are looking for one of this kind in the market, it is important to keep certain factors in mind. The following are some of the things you may want to look for in a terrestrial telescope.

Correct-Image Diagonal

A terrestrial telescope needs to have a correct-image diagonal. In some cases, a regular telescope will be compatible with the provisions for the correct-image diagonal, but you may have to buy the actual corrector separately. In other cases, the correct-image diagonal will be inbuilt and you can use the device to view terrestrial objects during the day and celestial objects during the night. With a correct-image diagonal, you will be looking at the object as it is and there will be no distortions or inversions. This is the fundamental requirement of a terrestrial telescope.


The eyepiece of the telescope can completely change your experience of using the device. The eyepiece will dictate how powerful the image will be. Ideally, the eyepiece should also have coated glass optics so that your eyesight is protected when you are looking into the lens. Often the image can be quite bright, especially when you are looking at terrestrial objects during the day. But with fully-coated glass optics, you will be able to enjoy a great image without damaging your eyesight.


A telescope is not the most inexpensive thing in the market, so it always makes for a better purchase if the telescope also comes with certain accessories. Some of the most important accessories that a telescope must come with include an adjustable tripod, replaceable eyepieces, Barlow lens, a finderscope and provisions for easy and smooth manual tracking. These accessories are what will make the telescope a complete buy and allow you to make the most use of it.

Manual Tracking

If you are inclined towards astronomy and want to become better in the field, it is important to keep experimenting and exploring more. With a slow-motion manual tracking ability, you will be able to cover more of the sky and discover more things. Manual tracking is the best way to practice more with the telescope and better your skills. Slow-motion manual tracking is a great feature to have in astronomical as well as terrestrial telescopes.
