What is Telescope Eyepiece?
An eyepiece, or ocular lens, is a scope lens that is connected to a variety of optical devices such as telescopes and microscopes. Telescope eyepieces focus the light from a telescope into the image and determine the magnification of the image. The objective of the lens or mirror is to collect light and bring it to focus on creating a perfect image. It is used to make a focal point of the objective to magnify the image. The amount of magnification depends on the focal length of the eyepiece.[source]
Types of Telescope Eyepieces:
Figure: Example (from right to left) of 0.965″ (24.5 mm), 1.25″ (32 mm), and 2″ (51 mm) eyepieces.
There are mentioned six standard barrel diameters eyepieces for telescopes. The barrel sizes (usually indicated in inches) are:
- 965 inch. (24.5 mm) – This is the smallest standard barrel diameter and is usually found in any ordinary telescope retail shop. Many of these eyepieces that come with plastic lenses.
- 25 inches. (31.75 mm) – The most popular and commonly use barrel diameter is 1.25 telescope eyepiece. With longer focal lengths of at least 40mm, the edges of the barrel itself place into the view-limiting by its scale.
- 2 inches. (50.8 mm) – This larger masterpiece barrel size in 2″ eyepieces helps to reduce the limit on focal lengths. About 55 mm is the upper limit of focal length with 2″ telescope eyepieces. These barrel sizes are threaded to take up to 49 mm filters.
- 7 inches. (68.58 mm) – Best 2.7″ telescope lenses are made by a limited number of manufacturers. They allow for slightly larger fields of view. Many high-end focusers now accept these eyepieces.
- 3 inches. (76.2 mm) – The even larger barrel size in 3″ eyepieces up to 5 lbs. in weight allows for extreme focal lengths and over 120° field of view eyepieces.
- 4 inches. (102 mm) – Highly recommended these eyepieces are commonly used in observatories. As these lenses are rare and made by very few manufacturers.
Telescope Eyepiece Guide for new users:
- Focal Length and Magnification
Firstly, your eyepiece and telescope’s focal length are key issues to understand because off it affects eyepieces magnifying power. The distance from the primary mirror to the point where the light is focused is called Focal Length. Magnification can be measured by simply dividing the telescope’s focal length by the focal length of the eyepiece.
- Field of View
Magnification affects the apparent field of view, resulting in what we call the actual or true field of view. Apparent field of view is the measurement of a window’s fitness inside a telescope optics. To calculate the actual field of view just divide the apparent field of view by magnification.
- Telescope Eyepiece Sizes
The diameter of the eyepiece tube is described by the size of the barrel. The eyepiece’s focal length and the barrel size should need to determine when you up to purchase one. Most of the eyepieces come in two different barrel diameters size: 1.25 inches & 2 inches and some are rare in size.
- Zoom Eyepieces
For a range of different focal settings zoom, eyepieces are the best choice among others. Most of the zoom eyepieces usually come in focal lengths of 7 – 21 mm and 8 – 24 mm, even you can customize the focal lengths if you ready to spend some extra money on that.
- Eye Relief
Eye relief is part of an eyepiece’s optical design. It is to keep your eye in a distance from the lens to make you comfortable to see the entire field of view. Even it is an essential safety matter for those who wear glasses. Keep at least 15 mm distance for a good long eye relief regardless of the focal lengths.
- Exit aperture
The total size of the main optic which gathers incoming light is called Exit aperture. To calculate the eyepiece’s exit pupil, get the focal ratio of your telescope by the telescope’s focal length in millimeters divided by the telescope’s aperture in millimeters. Now just divide the telescope’s focal length by its focal ratio.
