The StellaLyra Zoom eyepiece from First Light Optics offers a quality, well-built zoom eyepiece that offers bright high contrast views with excellent field flatness, very little false color and low distortion. Zoom eyepieces have the capability of adjusting their focal length while remaining connected to the telescope.
The StellaLyra 8-24mm 1.25″ Zoom eyepiece is well suited for outreach use, terrestrial observing and solar observing thanks to the convenience of a range of magnifications without requiring a physical change of eyepiece. In instances where you need to quickly reduce and increase magnification repeatedly, this eyepiece will save you from having to switch out eyepieces in rapid succession.
The StellaLyra Zoom eyepiece includes Lanthanum glass lenses to reduce chromatic aberration for clean, crisp views. The eyepiece focal lengths are parfocal across the zoom range so they require little or no focus adjustment when changing magnifications. The 20mm eye-relief is suitable for use with eyeglasses. The eyepiece features a 4-position twist-up eye-guard for comfortable viewing. It is well made from anodized aluminum with a tactile rubber grip for comfort and security.
