William Optics 1.25" 90-deg Erecting Prism Diagonal for RedCat 51 III WIFD Telescope Only (Not compatible with Redcat 51 v1, v1x, v2, or v2.5 (L-RC51II-U)
This high-quality William Optics erecting prism diagonal provides a "correct" image when observing with the William Optics RedCat 51 III WIFD telescope. When observing with this diagonal, "up is up" and "left is left" which makes it the perfect accessory for terrestrial daytime observing. The precisely engineered diagonal prism is made from anti-reflection coated BAK4 glass for maximum image quality and light transmission. It also includes a matte blackened interior to reduce internal stray light reflection and maximize contrast. The diagonal is made from CNC-machined 6061T aluminum and incorporates a silver aluminum anodized plate.
Its 1.25" barrel accomodates any 1.25" eyepiece. However, while many eyepieces will reach focus, not all will be able to do so due to the limited backfocus availability. We are unable to advise you which eyepieces may come to focus and which might not.
