The SV215 zoom eyepiece features a parfocal design. You don't need to refocus regardless of the focal length. (However, slight adjustments may be necessary.) The SV215 zoom eyepiece is primarily suitable for mid-to-high-end short-focal-length refractor telescopes and is mainly for high-magnification observations of the moon and planets. During the zoom process from 3mm to 8mm, the SV215 zoom eyepiece maintains a constant field of view of 56 degrees, which remains unchanged, providing the user with a completely different experience when using the zoom eyepiece. Simultaneously, the exit pupil distance remains unchanged at 10mm. Tube connection length: 36mm. For magnification adjustment, the SV215 continuous zoom eyepiece features a click-stop design. Clicks at 3, 4, 5, 6, 7, and 8 mm allow for quick and precise changes to preset magnifications. The SV215 zoom eyepiece features a lens configuration of 6 elements in 4 groups. Full multi-layer coating provides excellent clarity, contrast, and color correction. The SV215 zoom eyepiece features a foldable, removable, environmentally friendly rubber eye mask and a non-slip rubber protective ring. It has a safety undercut for a secure fit in the eyepiece holder. The interface supports the attachment of standard 1.25-inch filters. If you need to zoom in, rotate the zoom ring above the numbers. Rotating it will also raise the eyepiece. Note: It is normal for the focus ring to be slightly stiff when using it for the first time. It will gradually become smoother after using it a few times.
