Product Details

There are a number of things that you will thoroughly enjoy as an owner of this "StarGuider" 7-21mm 1.25” zoom eyepiece.

You’ll enjoy the high quality par-focal range which allows an observer to easily transition from low to high powered viewing without changing eyepieces! The knurled rubber grip and non-click stop adjustment mechanism will ensure that the observer can smoothly find the best magnification and field of view that the target object and seeing conditions will allow. In addition, a 30 to 43 degree field of view range combined with very generous eye-relief and a foldable rubber eyeguard makes this eyepiece well suited for eyeglass wearers and non-eyeglass wearers alike! The eyepiece is threaded to accept standard 1.25" astronomy filters.

Made with high quality multi-coated optics, this eyepiece will be providing high contrast views and unparalleled ease of use for years to come.
