Eyepiece DeltaOptical Super View 15 mm 1.25″

DeltaOptical Super View 15 mm 1.25″ eyepiece

The DeltaOptical Super View 15 mm eyepiece belongs to the popular GSO SuperView series - one of the best-selling lines in its class for many years. This series has earned a firm place among amateur astronomers thanks to its combination of excellent optical quality, affordable price and versatile usability. Whether you are a beginner just starting to explore the night sky or an experienced observer looking for a reliable everyday eyepiece, the Super View 15 mm will not disappoint.

Optical construction

The 4-element optical design of the DeltaOptical Super View eyepiece provides a comfortable eye relief while delivering outstanding sharpness across the entire field of view. This is especially appreciated by observers who wear glasses, as well as by anyone looking for comfortable, fatigue-free viewing sessions. Every lens element features multi-layer anti-reflection coatings that minimise light losses caused by reflections and maximise light transmission. The result is an image with high contrast, vivid colours and minimal ghosting or flare. The lens edges are blackened to eliminate unwanted scattered light inside the barrel, further contributing to excellent contrast in the observed image.

Barrel and mounting

The eyepiece barrel has the standard 1.25″ diameter and is manufactured without a safety groove. This is an intentional design choice - it eliminates the risk of accidental tilting of the eyepiece in the focuser drawtube and at the same time allows secure and firm clamping with standard thumbscrew rings. As a result, the eyepiece is well suited for more demanding mounting configurations and for use in binocular viewers.

Versatility - Moon, planets and deep-sky objects

The 15 mm focal length places this eyepiece in the mid-magnification category, which is widely regarded as the most universal for astronomical observation. The Super View 15 mm is an ideal choice for observing the Moon and planets - when used with a telescope of medium focal length, it delivers magnification at which fine details become clearly visible: surface features on the Moon, equatorial cloud belts on Jupiter, the ring system of Saturn or the polar caps of Mars. The comfortable field of view provides a good sense of context without the feeling of looking through a keyhole.

The eyepiece also excels at deep-sky observation. Planetary nebulae such as the Ring Nebula in Lyra or the Dumbbell Nebula in Vulpecula are well visible with pleasing contrast against the sky background. Globular clusters such as M13 in Hercules or M22 in Sagittarius resolve into beautiful sprays of stars in the Super View 15 mm. The multi-layer anti-reflection coatings ensure that even the faintest objects are not lost in unnecessary reflections. The eyepiece is also suitable for fast telescopes with a small focal ratio (f/4, f/5), where cheaper eyepieces commonly suffer from coma or other edge distortions.

Binocular viewing

Thanks to the absence of a safety groove and the secure clamping provided by thumbscrew rings, the Super View 15 mm is an excellent choice for binocular viewing. Using two identical eyepieces in a binocular viewer creates an unforgettable three-dimensional impression of celestial objects and significantly reduces eye fatigue during extended sessions. Both eyes work simultaneously, which promotes deeper relaxation and a more immersive experience of the night sky.

Why choose the DeltaOptical Super View 15 mm?

GSO SuperView eyepieces distributed under the DeltaOptical brand represent a proven choice for astronomers of all levels. They combine quality optical craftsmanship with a robust mechanical construction and an attractive price. Multi-layer anti-reflection coatings, blackened lens edges and a 4-element design are by no means standard features in this price category - yet the Super View series offers all of them. The Super View 15 mm 1.25″ eyepiece is therefore an excellent investment both for beginners looking for their first quality accessory and for more experienced observers who want a reliable, high-performing mid-magnification eyepiece always within reach.
