3. Celestron Luminos 19mm Eyepiece

View at Amazon

The Celestron Luminous is one of the best telescope eyepieces on this list. It comes in 19 mm, 23 mm, and 31 mm (all are sold separately). This is better than your standard option, which is apparent in the retractable eyepiece. This is not the right option if you are looking for something small and portable. But with this telescope eyepiece, you’re going to get incredible clarity more than any other eyepiece.

The reason why there are so many lenses inside a professional eyepiece like this is that they work together to reduce issues with imaging. So you’ll find very little ghosting with the luminous range (reflection between lenses), astigmatism or field curvature (spherical aberration).

See Also: Best Telescopes for Viewing Planets

All Luminos eyepieces are multi-coated to improve light transmission by means of multiple lenses, which means a better image at your eye and the edges of the lens are blackened to improve contrast.

This happens because the darkened edge stops light escaping through the eye barrel and bouncing around free, keeping the picture bright.


4. Meade Instruments Ultra Wide Angle 20mm 2-Inch Eyepiece

View at Amazon

A Meade Ultra Wide Angle 20 mm eyepiece is a tool that you need if your telescope is designed for less than a 2-inch barrel. It is not also disappointing if your passion is based on deep-sky observations.

Telescope Eyepiece Buyer’s Guide

Focal Length

In optics, the focal length is the distance to the point where the light is focused from the primary mirror or lens. This is the point at which an image is made. The focal length of your eyepiece and telescope is important because it determines the eyepiece’s magnifying power. The length is measured in millimeters.

Magnification

It is important to understand the magnification, so you can get the best of your eyepiece range. A low magnification creates sharp and bright but small images. High magnifications create bigger pictures, but they are dimmer and can be blurry as the magnification limits are pushed.

Field of View

The apparent field of view is an indicator of how well a window fits into the optics. You can see a number written in degrees if you look at your eyepiece. An eyepiece with a narrow field of view focuses on a smaller part of the sky than a larger-viewed eyepiece. The viewing area can range from very narrow (25°–30°) to very wide (80°+).

Eyepiece Sizes

The size of the barrel is one of the things you may overlook when you buy an eyepiece. While the quality and form of views depend on the eyepiece’s focal length, the dimensions of the barrel indicate the diameter of the tube. The focal length is not affected. It literally tells you whether it fits into the barrel of the focal length of your telescope.

Eye Relief

Eye Relief defines the distance between your eyes and the eyepiece lens. Traditionally, the eye relief is proportionate to the focal length: the shorter the focal length the shorter the eye relief. In addition, the more modern eyepiece designs help people who wear glasses get more long-eye relief. Eyepiece eye relief is an important specification to consider for those who want to keep their glasses on when using a telescope.

Use a Barlow Lens

Using extra optics can often give you a new perspective in stargazing. The problem is that those Barlow lenses are costly.

It is good to have the Barlow lens when you are starting out, since it allows you to gather better and different eyepieces. Barlow lenses are useful for beginning telescope users who own scopes with smaller apertures. However, as soon as you move up to more expensive scopes and eyepieces, Barlow lenses are unnecessary.

The use of Barlow lenses, which increase magnification of the object being viewed, should not be recommended with larger and better telescopes, such as 12″ and higher quality eyepieces. For instance, when you purchase inexpensive or low-quality eyepieces, you will likely only end up buying 2 or 3 eyepieces.


Types Of Telescope Eyepieces

Plössl 

Plössls have wide field of view (around 52°), which can be used well for astronomical observing. The short eye relief makes shots with focal lengths of less than 12mm is an issue. “Eye relief” means the distance between your eye and the eyepiece at which you can see the entire field of view.

We do not reccomend Plössl eyepieces. You can get better eyepieces for the same ammount of money or less.

Orthoscopic  

The benefits of these eyepieces is hight quality, but sadly, the apparent field of view is reduced as these eyepieces are with a small angle of view. These are possibly used by people with glasses due to their large eye relief. They are especially useful for observing the Moon and planets.

Aspherical 

This eyepiece is simply a wonderful one to have. They have very good picture quality with wide apparent field of view. They are not expensive, and that’s why everybody should own one.

Nagler 

The most impressive quality of the Nagler is its huge field of view. It has an ultra-wide 82° field of view.


Frequently Asked Questions

img source: spacetourismguide.com

 

How Do Eyepieces Work?

An eyepiece takes light from the telescope and makes the image more visible for us. You can have a clear view of the celestial objects if the eyepiece can absorb light effectively.

A little bit of light is taken away when it travels through the lenses of your eyepiece. To prevent the light loss, the lenses are often coated with layers of substances such as magnesium or calcium fluoride.

How Many Eyepieces Do I Need?

There is no “optimal” number of eyepieces you should own, but you can improve your chances of observing the appropriate power for the sky conditions at the time by using a few different telescope eyepieces. To get an object in the field of view of the telescope, you will often start with low power (25 mm or 30 mm focal length).

If you want to see a clearer image, try a smaller-power (shorter focal length, for example, an 18 mm or 15 mm eyepiece) eyepiece. As long as the higher-power eyepiece yields the right amount of light, size, and detail, try to keep adding more powerful eyepieces until you find the perfect combination.

What Diameter Eyepiece Should I Buy?

The eyepiece’s diameter depends on what your telescope focuser supports. Most of the telescopes are built to hold eyepieces of the following sizes: 1.25″ and 2″ with interchangeable adapters.

To begin with, you should limit yourself to a particular barrel length.  As you would be buying more costly deep-sky filters in the future, you would prefer to purchase one eyepiece (not two, for 1.25” and 2”).

On the night sky, you need to use two eyepieces that are 10 mm and 24 mm to see 90% of the objects. When it comes to eyepieces, 1.25″ barrel eyepieces are better because they are more popular and the barrel sizes do not have a price difference. Even so, 2” deep-sky filters are almost twice the price.
