An eyepiece is a lens that is attached to a telescope to magnify an image bringing the subject in focus closer by collecting light to create an image that is observed through the telescope.
Investing in a telescope eyepiece can hugely impact the optical system of your telescope.

Best Telescope Eyepieces Buying Guide
As there are many telescope eyepieces available there are several factors that we would advise you to consider before making your purchase.
From the different types available and the different characteristics boasted by each, the following criteria will aid you during the purchasing process.
The Apparent Field of View
The apparent field of view is a measurement that identifies what your telescope is going to show when your eyepiece is attached to the lens.
Simply put, the field of view refers to the viewing angle and everything visible to you when you look into the telescope.
The field of view can differ between the different eyepieces with some being wider than others and some being truer to what you can see rather than apparent.
The Focal Length and Magnification
The focal length is an important factor that can determine the magnification of your eyepiece.
Essentially, the focal length refers to the power of the lens and the overall magnification of the setup.
A telescope with a shorter focal length tends to have greater magnifying power.
The Eye Relief
As expected the eye relief is going to affect how comfortable the lens is and how well you can observe the image through the lens of the telescope. Ideally, your telescope should be equipped with long eye relief because this is going to make it much more comfortable.
To put it simply, the eye relief refers to the distance between your eye and the lens and tends to be proportionate to focal length. For this reason, a telescope with a shorter focal length is going to provide you with shorter eye relief.
Set or Individual Eyepiece
While some eyepieces are sold in individual quantities, others are available in sets. The type that you choose is going to depend on your requirements. You may not require all of the pieces inside a set if you already have some and you are simply browsing the market for a particular lens.
If a telescope is a new purchase and you don't yet have any eyepieces a set may be a viable purchase that will provide you with a variety so that you are ready to begin using your telescope. A set is a great option that allows you to experiment with different lenses.
You will also find that some brands offer eyepieces in single quantities although they will be available in different size variations.
The Material Construction
Most eyepieces boast a tough material construction, typically composed of anodized aluminum. As a tough material, aluminum creates a robust external housing that is sure to withstand daily use.
Should you accidentally drop the eyepiece, you can be sure that it isn't going to deteriorate quickly. The material construction is also likely to impact the effectiveness of your eyepiece by influencing the overall quality of the image that you are observing.
Many eyepieces will come with rubber guards which ensures that the telescope is comfortable when pressed against your eyes.
The comfort of the eyepiece is super important because you don't want to be holding your telescope against your eyes for a lengthy amount of time if it is made from tough materials that aren't soft against the skin.
Alternatively, the rubber grips also make the eyepieces comfortable for glasses wearers by ensuring that they can use the telescope without having to worry about the lens pressing against their glasses or skin uncomfortably.
Many brands manufacture high-quality eyepieces. Of course, as with most niches, particular brands within this industry are more well known than others.
Those with well-known reputations are typically associated with producing high-quality products of which are commonly sought after by customers that often make their purchases with this brand.
While you may wish to invest in a more well-known brand, there are many other options from less known brands available too. Should you wish to purchase from those less known brands there are still many high-quality products available.
A telescope eyepiece that is worthy of your purchase is defined by how you intend to use it and your particular requirements.
Eyepieces retail at various prices with some that are much more affordable than others. Your expertise in using a telescope is likely to determine how much you are going to spend.
If you are a beginner and this is one of the first eyepieces that you are going to be buying, you may not wish to spend a lot as you are likely to want to experiment with using it first.
Those with a professional telescope may want to invest in a slightly more expensive eyepiece to coincide with this, there are options available to cater to this too. The quality is likely to be reflected in the price of the eyepiece and it is important to ensure that your chosen eyepiece satisfies your needs.
