Description
Product Overview
The Pomya 1.25 inch diagonal prism is engineered for refracting telescopes that use standard 1.25 inch eyepieces. Constructed from a robust plastic body and high‑quality optical glass, the prism delivers a clear, acuminate image while correcting the inverted and reversed view typical of telescopic optics. Its 45° angled mirror aligns the image to a comfortable viewing position, and the included dust cover protects the glass surface from contaminants, extending the product’s lifespan.
Usage
Designed for backyard stargazing, planetary observation, and educational astronomy sessions, this diagonal fits seamlessly onto most refractor mounts. Whether you are tracking planets, nebulae, or lunar features, the 45° angle allows a natural head‑down viewing posture, reducing neck strain during extended sessions.
