Svbony variable focal eyepieces are an ideal choice for both beginners and more advanced visual observers. Their wide range of adjustments allows for perfect magnification selection without the need to exchange the eyepiece for another.

The Svbony SV230 1.25" / 2" is an eyepiece with a variable focal length of 8 - 20 mm and an apparent field of view of 57 - 72°. In order to ensure sufficiently high contrast and excellent detail, all lenses are fully multi-coated (FMC) and their edges are additionally darkened, which minimizes the risk of internal reflections. The eyepiece optics are parfocal throughout the entire focal range, which allows changing the obtained magnification without having to refocus.

The eyepiece is enclosed in a metal housing with a thread enabling the installation of 1.25" and 2" filters.
