## Description

The SV215 zoom eyepiece is designed to provide the good balance of contrast, comfortable eye relief, and resolution for the critical planetary observer, particularly those with ultra-premium short focal length refractors. Parfocal Design: SV215 zoom eyepiece maintains focus throughout the zoom. You don't have to refocus when you magnify. Click /Stops: Improve the customer's hand feel of variable times adjustment operation. Smooth zoom action with click-stops at 3, 4, 5, 6,7 and 8mm for quick changes to precise preset magnifications. Apparent Field of View: 56°：The field of view will not change with the change of focal length, the process of doubling to give customers a fixed point to pull into the visual enjoyment. Eye Relief: 10mm: The transformation ratio customers do not need to adjust the distance of eye relief, so as to adapt to the observation environment again and improve the observation comfort. Fold-down rubber eye cup: Be friendly to people's eyes. A rubber grip ring and with safety undercut for a secure fit in the eyepiece holder.

Review: Steht in nichts nach
Review: I have been a lunar and planetary observer for over 60 years and a retired optical engineer. Planetary eyepieces are easier to test for aberrations due to their smaller AFOV. They are optimized for viewing objects in the center of the field. When visually observing planets, the main requirements, in order of importance, are sharpness, contrast, and color fidelity. In my experience, the best planetary eyepieces are simple, time-proven designs with the fewest elements (less than 6). Today's visual observers are primarily interested in observing deep-sky objects using wide-field eyepieces with 4 times more lens elements than traditional planetary eyepieces. Some younger observers have never observed the planets with high-quality 3 to 4 elements eyepieces. The Svbony has 6 elements, but it is a zoom eyepiece, and it manages to perform admirably. Jupiter is the premier planet to test eyepieces due to the low contrast of features in the belts and zones. It doesn’t take magnification as well as Saturn, so you can quickly see differences. I didn’t evaluate comprehensively to determine if the Svbony falls short. With good seeing, if you can’t see any difference in the first 30 minutes switching eyepieces in and out, there is little reason to spend more time seeking an answer. If it takes this long, then there is no practical difference. Over the years, I spent too many hours at the telescope over several nights to arrive at a final verdict. To what end? This is time better spent observing. The performance of this eyepiece is outstanding. I had a selection of eyepieces to compare with the Svbony zoom, i.e., 3, 4, 5, 6, 7, and 8 mm. Some were high-end eyepieces, including orthoscopics, Plossls, Televue Radians, and Delos. After an hour of observing, I could not see any significant differences in the image quality of the Svbony compared to the other eyepieces. In a few cases, the expensive widefield eyepieces with many lens elements faired worse in detail. While image brightness and contrast were good, the definition of delicate structures in Jupiter’clouds was lacking. Zoom eyepieces usually require refocusing when switching focal lengths. My sample was parfocal. Depending on the seeing, when focused at the shortest focal length, 3 or 4 mm, there was no need to refocus at the 5, 6, 7, and 8 mm settings. In summary: Likes: Cost. Functionality (beats switching eyepieces). Mechanical quality (parfocal, click stops). Optical quality (sharpness, contrast, flat field) Dislikes: Heavy (built like a tank). Tapered eyepiece barrel (hard to clamp with compression ring). The eyepiece barrel length is too long. The barrel cap keeps falling off. A good analogy between a zoom eyepiece and a fixed focal length eyepiece is a Swiss army knife compared to a hunting knife. Svbony has managed to even the playing field. I highly recommend this eyepiece for owners of short focal length refractors (less than 800 mm).

## Features

*by R***D on 31 January 2025*

Zoom Eyepieces aren't always well designed and sometimes the image is not as good as a fixed focal length. The Zoom Eyepieces that work decently, usually cost a small fortune. SVBONY is the exception, it works extremely well and is priced reasonably. While I prefer fixed focal lengths, This Zoom eyepiece is especially useful if you're travelling to site and don't want to carry a lot of gear. Highly recommended
