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 zoom 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.

Please Note: Zoom eyepieces will produce a ratting sound when shaken. This is due to the clearances required for moving parts of the zoom mechanism, and does not indicate defects or loose lenses. This sound is completely normal.
