Vixen 10mm telescope eyepiece with fully multi-coated optics. This eyepiece features a newly designed optical system that produces a flat image plane and corrects chromatic aberration for a sharp, clear view. When attached to a telescope with a focal length of 520mm, it allows for approximately 52x magnification. For those who wish to observe planets, we recommend combining it with a 2x Barlow lens.
