Telescope Eyepiece Set Review: Are the 6mm, 12.5mm and 20mm Plossl Options Right for You?

This 1.25-inch Plossl set offers three focal lengths, a listed 50-degree field of view, filter threading, and glasses-friendly eye relief for lunar and deep-sky viewing.

Last updated Aug 24, 2026

Choosing astronomy eyepieces means balancing flexibility, viewing comfort, and field width. A set can make sense when you want several focal-length options, but a single specialized eyepiece may be more suitable if your observing style is narrowly defined. The Telescope Eyepiece Set, 3 Pics Plossl Eyepiece 1.25" 6 12.5 20mm is aimed at shoppers who want a compact starting range for lunar and deep-sky observations.

Quick verdict

At USD 57.58, this set is a practical fit for someone who wants three listed focal lengths in one purchase and expects to use standard astronomy filters. Its strongest details are the 4-element Plossl design, approximately 50-degree apparent field of view, fold-down rubber eyeguard, and eye-guard design described as convenient for glasses wearers. The main compromise is that the field of view is specified at about 50 degrees, so shoppers focused on an especially expansive wide-angle experience should consider that specification carefully.

The clearest reason to choose this set is its range: the title lists 6mm, 12.5mm, and 20mm eyepieces, giving the user multiple focal-length choices for changing observing situations. The description specifically points to broad-field lunar observations, medium-sized star clusters, cloudy nebulas, and other deep-sky targets. Threading for standard astronomy filters also gives the set a straightforward way to pair with compatible viewing accessories.

The limitation is the set's defined 50-degree AFOV. That is a concrete specification to weigh if your priority is a very broad-looking view rather than the listed Plossl format. The USD 57.58 price also makes the set more compelling for shoppers who will use several focal lengths, rather than someone seeking only one eyepiece for a single purpose.

Who it suits

This telescope eyepiece set suits beginners or casual observers building a varied kit around lunar viewing, star clusters, and nebulae. It is also a sensible match for eyeglass wearers because the description calls out a custom-fitted soft rubber eye guard designed for convenience with glasses. The included dust caps are intended to protect the eyepieces from dust and moisture between observing sessions.

What stands out from the listed details

The combination of a 4-element Plossl design, long eye relief, and fold-down rubber eyeguard emphasizes comfortable, conventional viewing rather than a highly specialized setup. The 1.25-inch format is clearly stated in the title, while the threaded barrels are described as accepting standard astronomy filters. Those details make the set relevant to shoppers who want to explore both ordinary lunar views and filtered deep-sky targets.

Meaningful trade-offs

This is a set built around the listed Plossl configuration and three focal lengths, not a single-purpose accessory. Its approximate 50-degree field and conventional eyepiece design may suit broad lunar and deep-sky use, but shoppers should match those specifications to their preferred viewing style before choosing it.

Bottom line

The Telescope Eyepiece Set, 3 Pics Plossl Eyepiece 1.25" 6 12.5 20mm is worth considering when you want a multi-focal-length astronomy eyepiece set with filter threading and glasses-friendly viewing details. At USD 57.58, its appeal depends on using the 6mm, 12.5mm, and 20mm options rather than needing only one narrowly focused eyepiece.
