This finder scope is the lightest 50 mm on the market. It weighs only 19 ounces and works with our standard 50 mm ring systems. You may use other 1.25" eyepieces with this finder scope, converting it to a small telescope. It performs very nicely with Naglers! The 50 mm objective gathers 50 times the amount of light your naked eye does so you can more easily spot dimmer objects in the night sky.
Finderscope dimensions: 9" long, 2 1/4" wide and 6" high. The main tube is about 2.16" in diameter and the dew shield is about 2.3" in diameter.
This finder scope comes in a neutral matte black finish that goes well with any telescope regardless of color. Separate helical focusers allow you to first focus the crosshair reticle, then the optical focus. The angle of the prism and eyepiece may be rotated to place the eyepiece in the most comfortable position, but it may be necessary to readjust the finder scope once the eyepiece is rotated. We supply these finder scopes without rings so you can select the ring system that works with your particular telescope. Visit our 50-60 mm finder scope ring set page to determine and order the rings you will need.
Important! When installing mounting rings DO NOT unscrew the dew shield. The objective may fall out. Always unscrew the rear assembly (adapter, prism, focuser, eyepiece) from the main tube to install the rings.
*Rear thread size for all F050 models is M52 x 1mm

An outstanding finder scope. Excellent optically and well made. I really like the individual helical focusing feature - one for the cross hairs and one for the finder itself. Stars are pinpoints.
I also bought a Stellarvue 80mm finder scope. I use it as a nice low power RFT on nights when the weather is iffy or if I only have a short amount of time to observe. The 80mm yields pinpoint stars as well with very good contrast.
Very nice, replaced a pos that cost half the price. Good bright view, smooth helical focuser. My illuminator from another eyepiece fit the hole in the one provided.
I think it’s a nice high quality build. Instant upgrade for my c8 setup with the default red dot finder. As an example, finding M31 in light polluted skies near the zenith very hard with a dot finder. So much easier with a quality finder scope and the diagonal makes it comfortable. For the newbies like me, yes this is a RACI image which means it matches the orientation of looking at the sky with the naked eye. This does NOT exactly match the default view through a C8 eyepiece - they are flipped left right. Nothing wrong with this - just don’t expect different!
Well made equipment, packaged very well & delivered on time.
The only optical finder we recommend on our scopes!
I have two of these finder scopes. One mounts on my SV-105 and I'm mounting the other on my Dob. I like the ability to change out eyepieces and the fact that they are RACI
I just purchased another 9x50 finder for my 12.5 inch dob. I already have one for my SV-105. I decided to add an optical finder in order to better find object near the zenith. I have a Telrad, but I was getting tired of straining my neck, and possibly falling of my ladder to locate objects at the zenith. I found this RACI finder to be perfect. In addition, it's at a very nice price point. I
Very clear and bright. I'm very happy
This finder scope is excellent, the image is clear and sharp, 90 degrees viewer is very comfortable. The possibility of changing eyepieces is very useful.
