## Features

- Three eyepiece sets; 4mm 10mm 23mm telescope eyepiece; for intricate details on bright objects; like the moon and Jupiter; also meets the needs of observing deep space targets such as medium sized star clusters and nebulae
- Wide angle 62° eyepiece; provide a wider apparent field of view; easier to locate objects and appreciate their surroundings; gives you an immersive viewing experience; suitable for scanning the starry sky or observing extended objects such as nebulae
- Aspherical lenses eyepiece; can reduce optical aberrations such as spherical aberration and coma; leading to sharper and clearer images across the entire field of view; the unique shape of aspherical lenses helps minimize distortion
- Advanced optical system; fully multi-coated telescope lens provides high light transmission; allowing more light to pass through; this results in brighter images; especially important when observing faint objects; for excellent image contrast

- Internal matting thread; the interior of the telescope eyepiece is painted black to effectively prevent stray light and reduce light reflection; thereby increasing the brightness of the image
- Anti-lost design; eyepiece interface recess portion can prevent the loss; it's a great Halloween birthday christmas gift
- To ensure the eyepiece you purchase is compatible with your telescope, please confirm your telescope's mount size, focal length, and other specifications before ordering. If you have any questions, please feel free to contact our customer service team. This eyepiece is compatible with refractor, reflective, and catadioptric telescopes. Before purchasing, customers should calculate the magnification, which should not exceed twice the objective lens aperture.

## Questions & Answers

**Q: Does 62° differ from regular**
A: Depends on what exactly "regular" means. An apparent field of view of 62° is more than what Huygens eyepieces (around 30-35°) and Kellner eyepieces (about 45°) have, the usual design for low-cost eyepieces such as those which are included with many beginner telescopes. Furthermore, 62° is also more than what Plössl and Super Plössl eyepieces (around 45-52°) offer, which are more expensive than Huygens or Kellner eyepieces and which are typically the first choice for better and yet affordable all-around eyepieces. On the other hand, 62° is slightly less than for Erfle eyepieces (around 65-68°, usually called WA for wide angle) and less than for ultra-wide angle eyepiece designs (anything beyond about 80°), both of which are more (WA) or much more (UWA) expensive than these aspheric eyepieces.

From my point of view, these aspheric eyepieces mainly rival Plössls, as they have about the same optical quality with a larger apparent field of view for less money. They are no match for WA and UWA eyepieces, both in optical performance or price, and they easily outperform Huygens or Kellner eyepieces.

**Q: Is it plastic or metal**
A: Hi Ken Wilson,the aperture of 4mm telescope eyepiece is aluminum alloy, and the mirror body is plastic, the lens is optical glass.hope this can help you!Sincerely Angela

**Q: What does the focal length mean on an eyepiece? I thought that was just for concave mirrors.**
A: All eyepieces have a focal length and it is very important to know what it is and what it means. Being made of usually several lenses, the eyepiece will have a focal plane. That's where the eyepiece focuses on and examines the image formed by a telescope, for example. Usually the focal length is printed right on the barrel of the eyepiece in millimeters. The importance of this is that you can determine the magnification of your telescope by knowing the scope's focal length and the eyepiece focal length. Say you have a telescope that has a focal length of 500 mm. this would also likely be somewhere on the scope or in the instruction manual. The magnification of the telescope will be the focal length of the telescope divided by the focal length of the eyepiece. So if you have a 500 mm focal length telescope and use a 4 mm eyepiece, the magnification is 500/4=125X. Or if you use the same scope with an eyepiece that has a focal length of 10 mm the magnification will be 500/10= 50X. An eyepiece with a focal length of 25 mm gives a magnification of 500/25= 20X. So you can see the shorter the focal length of the eyepiece for a given telescope, the more power or magnification. But there are drawbacks to magnification. With higher magnification you get a narrower field of view, compared to lower magnification. Also, for a given scope there is a limit to the amount of magnification it will handle. Too much magnification and the image gets blurry or soft. Magnification is not the most important number when using a telescope. There's more to it, hope can help you!

**Q: Will this fit on a galileo telescope?**
A: yes, it fit all standard 1.25" telescopes

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality
*by S***N on June 28, 2025*

Why did you pick this product vs others?:Very good eyepiece. Great for the value.

### ⭐⭐⭐⭐⭐ Crispy, Good quality, budget, eyepieces, wide angle, low cost
*by D***G on November 18, 2017*

I was shocked by how crisp the view I got from these eyepieces are when I first them in (one by one). I fully agree with previous comments that these eyepieces are decent and much much better than H20 (20mm) & SR4 (4mm) eyepieces I got together with the purchase of telescope.1) The build quality is not bad. Better than what I expect. The 23mm one is huge at hand and 10mm one is actually smaller than 4mm one. I would say 3/52) The optical quality is very good. The view is crystal clear and no apparent distortion. For 4mm one, the view is actually very crisp except for darker background. 4/53) The wide angle view is indeed with what it claimed. Viewing from 23mm even gives me a feeling like watching stars through a spaceship windows... 3/54) The eye relief is not very long but not bad. For 23mm, I can easily look through it when I wear eyeglass. Looking through 4mm is a little bit of harder to watch through with glasses but much better than my SR4, which is simply not possible. 2.5/55) The cost for those three pieces is low. $12 each. 5/5Overall, I would like to see that these eyepieces are well built, crispy clear and having wide angle view as advertised. In my opinion, if your budget is only about $50 and still want 3 decent eyepieces , this item is one ultimate budget choice.

### ⭐⭐⭐⭐ Good little starter set this is.. "Bronze line" compared to the "red line" or "gold line" sets
*by J***C on May 24, 2024*

With the current gold line and red line sets I'll call these the bronze line. Basic and cheap but more below. I am still learning collimation but I used a svbony laser collimator and supplied collimation cap and appears to be focused...They seem good, better than the 10mm and 25mm my virtuoso gti 150p came with.No eye cups. Didn't realize until I got them.Bought as 4mm 10mm and 23mm set, came in separate boxes In a plastic bag with dust caps on both ends.The 4 mm I didn't get the test during night but during day it seems ok for price. Dim and a little out of focus but might be me or the limit of my equipment or how i tested it. I did collimate but not going to knock it yet.The 10 mm was nice during night and day use, I have very little experience with other eyepieces other than the 'scope supplied 10mm and 23mm. Great views of full moonThe 23mm was odd, mine has a part of it that screws loose or tight at where you place into the 1.25" focuser. The silver part unscrews and I don't want to fully unscrew and damage or ruin it. Not sure if designed like that or a quality control issue. Works great other wise. Lol, turned it tight and it seems fine. Nice view of full moon.Two pics are one photo, but zoomed in on the second one. I just held an s20+ up to eyepiece. Don't remember which eyepiece I used, 10mm or 23mm might have used a 2x svbony Barlow. Second picture is an edited picture of the moon. More contrast and sharper to show details.Seems like a good starter set. Recommended brand. Getting the upgraded and seemingly well reviewed red line set soon..
