90° Everbrite Diagonal

I was blown away by how much brighter deep-sky objects appear through this diagonal compared to my old one. The 99% reflective coating really makes a difference on faint galaxies and nebulae.

Switching from my old mirror to this diagonal was like cleaning a greasy window — the difference in brightness is genuinely startling, and those faint deep-sky objects I used to struggle with now pop into view with ease. The 99% reflectivity claim isn’t just marketing hype; even on a moonlit night,

I was skeptical about dielectric coatings until I tried this diagonal—the 99% reflectivity is no joke, Jupiter's bands looked noticeably sharper than through my old mirror. The images just feel cleaner, with that extra pop of contrast that makes lunar observing a real treat.
