Traditional zoom eyepieces often experience changes in field of view and exit pupil distance during zooming. Likewise, as the focal length changes, telescope systems can noticeably lose focus, as most zoom eyepieces are not designed to be parfocal (unable to focus at the same point across all focal lengths). The SV215 telescope zoom eyepiece, with its precise structure and unique zooming mechanism, maintains a constant field of view and exit pupil distance without requiring refocusing during magnification adjustments.
1.Constant Field of View
Zoom mark 3-8mm click stop eyepiece，throughout the zoom range from 3mm to 8mm, the eyepiece performance remains constant at a field of view of 56 degrees, providing a completely different user experience compared to traditional zoom eyepieces.
2.Focus Design
No need to readjust focus regardless of how long you adjust the zoom.
3.Constant Exit Pupil Distance
Adapts to changing exit pupil distances and varying field stop diameters without needing to change eye position, enhancing the visual experience.
4.Carta Value Design
Quickly change predetermined magnifications, making it convenient for use in double deployments.
5.Foldable and Detachable Environmental Rubber Eyecups and Non-Slip Rubber Protective Ring
The SV215 1.25-inch 3mm-8mm Zoom Eyepiece is the first zoom eyepiece launched by the SVBONY brand specifically for planetary observations. Clicklock eyepiece features a 4-group, 6-element optical structure (including high-quality heavy lanthanide crown glass) and is designed with precision, weighing less than 200g, making it highly portable. 3-8mm click stop zoom eyepiece，Each glass surface is coated with a full broadband anti-reflective coating, and the edges of the lenses are treated to be mat
The stainless steel rubber sleeve supports standard 1.25-inch filter installation.Inside the packaging of the SV215, you'll find a cleaning cloth and two lens caps. The eyepiece is made entirely of metal, with zero play in the zoom adjustment, which produces a satisfying click sound during adjustment. It also includes a rubber grip, making it easy to hold, while the rubber eyecup provides comfort during use.
The SV215 is an excellent eyepiece primarily suited for short focal ratio mid-high-end refractor telescopes (portable OTA) and is ideal for observing the lunar surface and planets at high magnifications. It is particularly perfect for astronomy enthusiasts and professionals who seek greater flexibility in their observations.
