Many astronomy enthusiasts think of binoculars, but monoculars can also be used for astronomical observations.  In terms of weight, size, and even cost, a good single telescope may have its advantages.  After all, you’re only carrying half a pair of binoculars.  With a tripod and smartphone adapter, you can use a monocular for astrophotography.  Study the buying guide for astronomy monoculars 2022.

1. Different types of monoculars  

The best monoculars have three different optical designs: Galileo, Polo, and roof prism.  

(1) Galileo telescope  

They have simpler lenses built-in and are best for close-up shots.  However, they are not the best choice for stargazing.  

(2) Proprism  

Porro prisms were a standard optical design before the 1960s when roof prisms were not introduced.  They have a distinctive zigzag shape and tend to provide better light contrast.  Although they are considered obsolete, they produce images of at least the same quality as roof prism optically designed monoculars.  

Porro prisms can be made of two different types of glass.  The high-density glass, called BAK-4, collects more light from around the lens.  The second type, BK-7 glasses, is made of crown glass with shaded edges.  They are cheaper but of lower quality.  

(3) Roof prism  

The roof prism has a square shape that can be easily grasped by a child’s small hand.  Inside the lens, the light follows a more complex path, requiring a more precise optical design.  This makes the manufacturing process complex and therefore more expensive.  The best monoculars are made with roof prisms, which is why they are recommended for stargazing.  

2. Other factors to consider for astronomical monoculars  

Lens coating: Multi-layer coated lenses and BAK-4 prisms maximize light transmission for brighter, more detailed images.  

Durability: Better manufacturers will be more likely to provide durable equipment.  There are some very cheap monoculars on Amazon that can be fun for a short time but will provide poor optics and have a short life span if used regularly.  

Exit pupil distance: This is how far your eyes need to be from the eyepiece when viewing through the eyepiece.  This is especially important for people who wear glasses, because if you wear glasses, you will need a higher eye distance or your glasses will get in your way.  

Accessories: The most common are bags or suitcases.  Smartphone adapters and tripods are great choices for photography or astrophotography.  

3. What is the most powerful monocular?  

Because monoculars are more compact than binoculars, many stargazers think they will lose performance.  When comparing the power rating of a single telescope, they provide the same power as a binocular and are half the size.  

The power of a single telescope is determined by its magnification.  This is one of the most important factors to consider, as it determines the extent to which the device can enlarge the image you want to view.  Magnification is usually between 2x and 25x.  Double magnification means the target object is only twice as far away as the naked eye.  The monocular magnification level gives you your first indication of monocular power.  

Use premium astronomical monoculars to detect and capture meteor showers, planets, and stellar celestial activity.  Whether you’re looking for the best single-barrel telescope to explore the wonders of space or take pictures of constellations and planets, the Apexel telescope has enough options to suit your unique needs.  Enhance the quality of your viewing experience with astronomical monoculars designed for use at home and in any other outdoor space.
