Product Details

Most telescopes come with a small, straight-through finder telescope.  But many astronomers prefer the use of larger, right-angle finders that offer many more advantages. With a 50mm finder, you can hunt down fainter objects that you would not see in smaller 24mm or 30mm stock finders. "Correct Image" finders present a view that matches the orientation of the sky or the orientation of the stars in star charts. And, perhaps most importantly, your back and neck will thank you for using a "Right-Angle" finder and no longer subjecting them to various contortions at the telescope.

So if you are looking to upgrade your stock finder, GSO's high quality 8x50 right angle finder may be just what you need. It features a multi-coated 50mm achromatic objective, an Amici prism that provides a non-inverted, non-reversed correct-image, and single eyepiece cross-hairs that allow for precise centering of faint objects. The field of view is a generous 5.4 degrees.

The finder comes with a bracket and a dovetail base (you must select one of the finder bases from the drop down list above while ordering or it will not be included). The bracket has 2 nylon thumbscrews and one spring-loaded screw for quick and easy alignment of the finder with your telescope. The diagonal and eyepiece are not removable, changeable or rotatable. The finder comes with two protective end caps for the objective and the eyepiece.

This GSO finder telescope is available in a choice of white, black or silver/gray tube (The photo above shows the silver model). The dewshield, diagonal and eyepiece are black in all three models. The finder is easily focusable from the objective end by turning the objective assembly and locking focus using the focus lock ring just behind the dewshield. You may recognize these as the same finders sold by some other big name companies for a lot more.

Total Finder Weight = 18.4 oz (OTA = 11.5 oz, Bracket = 5.5 oz, Dovetail Base = 1.4 oz)
Tube Diameter = 53mm (2.09")
Dewshield Diameter = 58mm (2.28")
Tube Length (White/Black/Silver Section) = 86mm (3.39")
Total Finder Length = 205mm (8.07")

Additional Information

Telescope Mounting and Dovetail Base Choices

You can just purchase the finder with the bracket or also select of one of several optional bases for your telescope (see the drop-down list above for available choices that are in stock). For details of each base, including dimensions and specifications, please see the links below.

We cannot comment on compatibility of any of these bases with your specific telescope. Please use the detailed dimensions provided in the individual descriptions below to make this determination yourself.

If you intend to use the included finder bracket with your own dovetail base/shoe or with one already molded into your focuser housing, here are the "foot" dimensions of the bracket so that you can check compatibility with your "shoe."

  • Maximum width at bottom: 30.7mm
  • Maximum width at top: 23mm
