Description
Product Overview
The Pomya 45° Telescope Diagonal is a precision‑engineered 1.25 inch diagonal adapter designed for both astronomical and terrestrial observation. Constructed from premium optical glass, the mirror prism utilizes a 45 degree dielectric coating that maximizes light transmission, delivering bright and vivid images. Its all‑positive imaging design ensures that the view remains correctly oriented and upright, eliminating the need for additional image‑erection devices. Weighing only 3.17 ounces, the compact unit is easy to install and balances well on most telescopes. The included dust‑proof covers protect the optical surfaces from contaminants, extending the life of the prism and maintaining image clarity over time.
Usage

This diagonal is perfect for backyard astronomers, portable star‑gazing setups, and field biologists who need a clear, wide‑angle view of distant objects. Whether you are tracking planets, nebulae, or scanning the horizon for wildlife, the 45° angle provides a comfortable viewing position that reduces neck strain. The lightweight design makes it suitable for travel, allowing you to attach it to a variety of 1.25″ eyepieces and enjoy crisp, upright images in any setting, from dark‑sky sites to daytime nature walks.
