Easy to set up and use, great build quality.
Seems to be a quality product. It was easy to align with telescope lens and like the different patterns. Nice that it can be removed without having to recalibrate. This replaced the cheap one that came with a Celestron NexStar 6SE that it was too easy to accidentally get it out of calibration. Save the screws when you remove the old mount as the ones with this kit are too short. The William Optics is a great upgrade.
This is great for doing your GOTO alignment. The field of view is wider than a finder scope so the slightly-off alignment stars can't "hide" just outside the field of view. This William Optics Red Dot Finder is well worth the extra cost when compared to the cheaper plastic models on the market. As for as OPT is concerned ... it's the usual great service and fast delivery.
I got this, only to make it easier to find my alignment stars. My scope is a Ritchey-Chretien with a FL of 1370 so alignment of the mount to the goto targets in the narrow FOV is critical. But a classic 9x50mm Finder sometimes has the alignment stars out of the relatively narrow field of view so it’s hard to get alignment done at the start of the night. A black Finder scope looking into a dark sky is difficult to point at night. This red dot Finder, on the other hand, has a very large FOV. This makes it easier to find the alignment star and bring it into view in the main OTA. This red dot finder lets you choose from 4 different lighted shapes and 7 levels of brightness. Some people say that even the lowest brightness setting is too bright. But I’ve found that the lowest brightness setting, when used with the small dot shape, works well. This unit allows me to get aligned for the night quickly so my go to targets land in the center of the main scope. So I’m very pleased with the product. It’s money well spent, and the quality is the best I’ve seen ... exactly what I’ve come to expect from William Optics products. Thanks OPT!
I have used a few different types of finders in my years of astronomy, but none better than a Red Dot Finder. As with all William Optics Products, their finders are of high quality. I have four of these so I don't have to switch them out on my other scopes.If I buy a new scope, I will buy another one of these finders.
The inclination declination screw was cross threaded and not adjustable. OPT handled the issue quickly with a refund. Great store not so great red dot finder.
