Product Description
This finder-scope works with all of our standard 80 mm finderscope ring systems. The 80 mm finder-scope comes in a neutral matte black finish that goes well with any telescope regardless of color.
Included with each finder scope is our standard 23 mm, 50 degree, fully multi-coated cross-hair eyepiece, 1.25" helical focuser, rotating back (requires some finder re-alignment after rotation) and a fully multi-coated correct image erecting prism. This combination will give you a field of view of about 7 full moons or 3.5 degrees. This is about as large a field as the erecting prism will allow.
You can increase the field up to 5 degrees by converting it to a 2" straight thru finder scope using our 2" helical focuser. This focuser combined with out 26 mm wide field 2" eyepiece will give you a fov of about 5 degrees! Please note: you cannot use a diagonal in this configuration. If you add a diagonal the point of focus will be inside the diagonal so eyepieces cannot come to focus. So you are limited to straight through viewing with 2" eyepieces. Most eyepieces cannot provide a sharp field of view with a lens as fast as f-4.1. So while you will have an enormously wide field be advised that you will have coma as you move outward toward the edge of the field. Since this is a finder scope most people do not care about this as they focus on the center and watch for the object coming into the field of view with averted vision.
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 F080 models is M82 x 1mm

Stellarvue 13x80 finer with 80mm rings and E1002 Illuminator
I recently purchased this finderscope and mounted it on my Celestron Edge HD1400. The view through the illuminated reticle eyepiece is exceptionally clear and the overall finish and functionality is exemplary. I am also the proud owner of a superb Stellarvue SV90TBV Triplet and it is good to see that the high quality of the high end OTA's extends to the lower priced accessories. I was fortunate to find the product in stock and it was delivered in record time.

Stellarvue 13x80 mm Correct Image RA Finderscope - Matte Black - F080M2
Great image, looks good, light

Great dual views for outreach
At outreach events, I use the 80mm Stellarvue RACI mounted on my 8" Dob. 16mm ES 68 eyepiece gives 19x for a nice wide-field view, complements the Dob view for many targets.

Exactly what I had in mind
I needed a 80 mm to 100mm RACI optical finder for my 28 inch f/4 Newtonian that was light weight and the Stellervue 80mm finder was exactly what I needed.I also got the 80 mm rings, which perfectly fit the 80 mm finder. I've observed two nights under dark skies with it and I'm a happy customer.

Excellent Finder for a Larger Refractor.
I have this mounted piggyback on a 120mm doublet on a CGEM. The standard finder was "okay," but was both inconvenient, ergonomically, as well as having, at best, barely passable views. I have also utilized a "Brand X" 80mm short tube, and it was a bit better. This finder, however, gives much better "views," is more compact, simpler to adjust for various viewing angles, and is a bit lighter, increasing positioning options. The views are good, the contrast is excellent, and mounted in my already-on-hand ADM MDS and rings, is definitely the a better option for me. Oh, yeah, did I mention the workmanship is top-rate and it looks terrific, too? :)
