SVBONY SV188P Dielectric Mirror Star Diagonal, 1.25 Inch 90 Degree Mirror Diagonal, 99% Reflectivity Dielectric Coatings with Brass Compression Rings

This product gives full value for the money.It is a part of the telescope which can really make a difference,especially if the one being replaced is stock ,which came with the telescope.

Good product...it will increase brightness which is important in deep sky but it is not usful in daytime because it will show reverse image....

I didn't expect a 55$ diagonal to blow me away, but here we are. I recently purchased a Skywatcher 102mm StarTravel, the included 45 degree diagonal is perfectly usable for terrestrial, but for sky observing with objects high, it's much more of a problem. I was recommended this diagonal from a friend, and I was blown away with the difference in brightness and clarity of viewing. I have purchased a few SVbony products and they never fail to impress. This diagonal is no different. The mirror is huge compared to cheaper diagonals, and the dialectic coatings make it much brighter. If you need a diagonal buy this one with confidence. It comes with a brass band and not just a screw, so your eyepieces shouldn't get scratched up. Getting used to left and right being backwards, takes some getting used to, but it's definitely not a deal breaker. An unexpected side benefit, is the mirror is very easy to clean. (with a microfiber cloth) That was a problem with the default one that came with the scope.

Produto original, a qualidade do material é excelente, amei

Cumple con lo ofrecido y es una mejora a la diagonal que me vino con el telescopio, se percibe mucha calidad en la construcción del producto al ser completamente de metal.

I’ve been using this for a few weeks now with my refractor, and the difference between this and the "stock" diagonal that came with my scope is night and day. If you're looking for one single part to improve your viewing experience without breaking the bank, this is it. Brighter, Sharper Views The 99% reflectivity dielectric coating isn't just a marketing gimmick—you can actually see the difference. The blacks are deeper, and the stars are much "tighter." I noticed a significant reduction in light scatter when looking at bright objects like Venus or the Moon. Everything just looks crisper. Protects Your Gear My favorite feature is the brass compression ring. Most cheap diagonals use a simple screw that digs right into your eyepiece barrels, leaving ugly scratches. This ring applies even pressure all the way around, holding my heavy Celestron zoom securely without marking it up. Built for the Long Haul The body is solid metal and has a nice weight to it. It feels like a piece of professional equipment. The 90-degree angle is perfect for those high-altitude targets; no more neck strain trying to get under the tripod to see the Zenith. Bottom Line: It’s an Amazon's Choice for a reason. Great price, excellent build quality, and a noticeable jump in image clarity. It fits any standard 1.25-inch setup perfectly.

I've generally been happy with the various SVBONY items I have purchased. This diagonal seems well made, and does seem a bit brighter than older diagonals I have.
