Product carries full 2 year Celestron factory limited warranty (within US/Canada only).
(1) The finder eyepiece attaches to the diagonal using only two supplied screws. Even though there are three threaded screw holes, Celestron does not provide three screws.
(2) The included bracket/base have a custom design that is not compatible with other common finder base designs on the market (for example, the Synta/Vixen and Antares/Meade/Explore designs). We also do not have compatibility infomation about which telescopes the included finder bracket will/will not fit. However, the included finder base will fit on tubes that are 6" or larger in diameter (not aperture). It can accommodate screw hole spacings between about 27.5mm/1.08" (min) and 35mm/1.38" (Max). Please use this information to determine compatibility with your telescope.

Celestron 9x50mm Right Angle Correct Image Illuminated Finder Scope wiPros: Cons: Comments:
Solidly built finderscope which provides clear views and is easy to focus. It has an illuminated target finder but I have not installed this yet.
I found that when initially attached, the range of movement that the slots on the finder base allowed when screwed on the preset holes on the Celestron OTA made the finder a bit fiddly to align it on a C6. Apart from tightening the screw there is no means lock it securely when aligned.
I think it would not be hard for Celestron to improve this part of its design.
And while it is a nice view through the finder it is not unduly wide and you may well find you need an additional coarse finder (even a tube of cardboard) to easily get the target into the field of the finder.

Wow!Pros: Cons: Comments:
Upgraded from a stock 6x30 straight through. The brightness and clarity are great. And being able to rotate the viewing angle is a must for a SCT on an equatorial mount. I'm sure I would have spent 5 times this much on yoga, the inverse broken neck because the target is on the zenith move.

Very nice finder scope with a less than useful mount for me.Pros: Cons: Comments:
I really liked the finder, and the illuminated reticle on it is very nice. The mount though, it just didn't mount to my scope, and it is very low.
I bought a mount that stands off of my scope 3" so I can see through my finder, going from the finder to telescope eyepiece easier.

Great Finder ScopePros: Cons: Comments:
Most finder scopes force you to look from behind the scope and when you are looking at a star near the zenith it’s almost impossible to see. The fact that this scope has a diagonal makes all the difference. Solid product from Celestron.

Very Nice!Pros: Cons: Comments:
Cranking my neck to use the straight through 9x50 finder that came with my scope, was very inconvenient. This R.A.C.I. 9x50 is the answer. The illuminated reticule is a nice touch for this price range. I was concerned about the three alignment screws but they work well. Just be sure the large O ring is seated properly on the finder body. There is some adjustment needed from one viewing session to another but not much. I use a large Dobsonian and I'm used to fine tuning before views. All in all, this is a very nice, feature rich finder scope for a great price.

Better than expectedPros:
Accurate,Strong Construction,Easy to Use,Quality Lenses,AdjustableCons: Comments:
I have never been a fan of finder mounts that use an O-ring on one end, and have always been happiest with the type that have six thumbscrews, allowing maximum adjustment at front and rear. I was especially hesitant about a mount that has just two adjustment screws opposing a spring-loaded stud. But I needed a double cross-hair illuminated reticle to make alignment of a Nexstar 11 easier, and this was the best fit. However, I've been pleasantly surprised at how well this has worked. The O-ring is very tight, and took some effort to seat, so that end is quite firmly centered. The screws in the rear ring settle into an indent in the tube, which also helps stabilize the scope. The dovetail bracket fits the scope perfectly, with nearly dead-on alignment, so there isn't as much need for travel in the screws as when mating a generic finder and bracket combination. I'm still not sure about the spring-loaded stud, which is almost at full extension and at an odd angle. But in practice, it has held alignment well through multiple portable setup sessions, including a trip to a dark sky site over rough roads. Despite all the jostling, it consistently puts an alignment star so near the center of a 12mm crosshair eyepiece in the main scope, that I could probably get away with using it alone for alignment if I was in a hurry. Brightness and accuracy are good enough that when I have a narrower field eyepiece in the C11 and the go-to ends up a bit off, I can sometimes see the object in the finder and get it into view without having to switch to a wider eyepiece. Replacing the stud with a screw has thus shifted in priority to "one of those things I might get around to some day if I'm feeling like experimenting for the fun of it." The scope itself has a sharp, bright, wide field, which helps compensate for the poor initial north-seeking performance of the Nexstar that often requires considerable slewing to get to the alignment stars. The crosshair illumination is quite bright, but is very usable on its lowest setting. Being able to separately adjust the angle of the prism and crosshair is nice. I have the eyepiece angled toward the centerline of the scope, which works well for alignment stars, and keeps it from sticking out in a direction where I would probably bang it into a doorframe when carrying it outside. But I can still orient the crosshair with the motions of the scope. I do wish that the thumbscrews for angling the prism didn't stick out so far, but that's only an issue for initial alignment, when it's easy to grab one of them by mistake. Overall, a huge improvement over the stock finder and significantly reduced my setup time.

The finder scope itself works fine, but the O-Ring/two screw adjustment feature on the finder mounting rings doesn't work at all... I tried and tried to get the O-ring to engage properly, but it wouldn't. I have several other, better designed units from Orion that work similarly, and I've never had a problem with any of them. This finder is now in my Astronomy junk box.

Optically good Finder on a so-so basePros:
Lightweight,Compact,Easy to UseCons:
The rings use 2 screws and a spring, instead of 3 screws. Finder scopes get bumped at astronomy outreach programs, and this base lets the finder move.

Great aid for spotting your targetPros:
Strong Construction,Optics Are Clear,Mounting Is SolidCons:
Too Easy To Bump AlignmenComments:
Great device for spotting your target. Solid and good optics. Assembly on my Celestron 8SE was easy. Only bad thing is the alignment screws protrude out far enough that you can easily grab one of these when making an adjustment on the eyepiece position. If you twist the wrong screw, you don't loosen the eyepiece, you change the alignment. Shorter screws would be a good improvement. Otherwise, completely satisfied.

Great finder scope!Pros:
Quality Lenses,Easy to Use,Accurate,Strong ConstructionCons:
Very good finder scope, well built, a bit heavier than I imagined but its a perfect replacement for my C6 stock 6x30 finder.

Great addition to a scopePros:
Lightweight,Compact,Easy to Use,Strong Construction,Accurate,Quality LensesCons: Comments:
The illuminated crosshairs make setup of my Celestron a lot easier. I recommend you add this to your equipment if your scope is not permanently mounted and you have to align the tracker every time you use it.

Quality Lenses,Easy to UseCons:
This is a nice finder. You can adjust the brightness and has good views. It is a little heavy but works well. It looks great on my Celestron 6" Cassegrain scope and was easy to install.
