SVBONY SV188P Dielectric Diagonal for Refractor 1.25"
There are many 1.25" star diagonals on the market. Many of them have a mediocre mirror quality with 90% reflectivity (10% loss) and a plastic body. The 1.25" diagonal by SVBONY stands for a high-quality alternative to those cheap parts. It offers excellent image and mechanical quality. There's no vignetting over the full 1.25" field. SV188P features sophisticated, Multi-layered dielectric coatings that provide an astounding 99% reflectivity for maximum view brightness and sharpness.
SV188P Diagonals provides a comfortable 90-degree viewing orientation when observing the night sky through a refractor. When using the SV188P with Maksutov-Cassegrain (Mak-Cass) or Schmidt-Cassegrain telescope, you will need a special adapter.
Another advantage is the 1.25" nosepiece barrel is threaded to accept 1.25-Inch filters. Brass lock Screw and Brass Compression Rings feature more precision and prevent barrels or the surface of eyepieces from marring and scratching.
