Best Telescope Eyepieces – Buyer’s Guide

(Last Updated On: March 22, 2018)


Experts always suggest carrying an additional set of eyepiece with your old or new telescope. They are the most important accessory for a telescope, no telescope works without an eyepiece. Most companies provide eyepieces with their telescopes but the main problem with those is they are of cheap quality and do not do full justice with the telescope. High quality, well-made eyepiece can dramatically increase the performance of your telescope. So, if you are in a mood of getting some additional eyepiece for your lovely telescope you are at the right place. Here, our team has recommended Best Telescope Eyepieces available in the market from different brands but before that let’s try to understand how eyepiece work and how it affects the magnification power of the telescope.

 

a) Highest useful magnification

Before selecting the right eyepiece for our telescope, we need to first find out what is the highest useful magnification of the telescope. Sometimes beginners tend to get confused that magnification is the most important factor in the telescope, they buy their telescope thinking more the magnification better will be the power

 e.g. 500x magnification is good than 300x in a 5-inch telescope.

But that is not correct, there is an upper limit to any telescope, if you push the telescope above that limit the result will be a poor and blurry image.

 

How to determine the Highest useful magnification (Upper limit)?

To determine the highest useful magnification of telescope just multiply the telescope’s aperture (inch) with 50.

e.g. Highest useful magnification of telescope in normal condition of 5” telescope will be:-

Magnification= 5” (aperture) x 50 =250X.

 

b) Focal length

Focal length is the distance from the center of lens or mirror to the point of focus. The longer the focal length of the device the more powerful it is. It is measured in mm.

Choosing the right Eyepiece

Now to choose the right eyepiece, we just have to keep 2 points in mind. Highest useful magnification (already discussed) and eyepiece power.

Eyepiece power is calculated by dividing the focal length of the telescope with a focal length of the eyepiece.

Eyepiece power= Telescope (focal length) / Eyepiece (focal length)

e.g. Telescope having focal length of 1000mm combined with 25mm eyepiece gives 40x power. Same way, 10mm eyepiece with the same telescope will give 100X power.

Eyepiece Power= 1000/25 = 40x

Thus, using a different eyepiece of different focal length will result in different magnification.

We can play with different eyepieces as long as we are not crossing highest useful magnification of the telescope.

Try high magnification for the moon and nearest planets, medium magnification for brighter objects like galaxies or nebulas and low power eyepiece for locating deep sky objects because they give the widest field of view.

c) Misconception

There is one big misconception about the eyepieces is, if we have a telescope of XYZ brand then we can only use an eyepiece of same XYZ brand with that telescope. This is totally wrong if we have Celestron telescope we can use the eyepiece of Orion or vice versa as long as the barrel size of focuser matches with the size of the eyepiece.

In modern astronomical telescope 1.25” is universal standard size, some telescope comes with 2” size but they also provide an adapter that allows using 1.25” eyepieces.

d) Barlow lens

Barlow lens is another important accessory that sits between focuser and eyepiece. This affordable accessory can double or triple the power of your eyepiece.

e.g. 2x Barlow lens when combined with 25mm eyepiece and 1000 telescope focal length give 80x power.

Power= 2x (1000/25) = 80x.
