Astromania Artificial Star For Telescope Collimation – Dimmable, 50µm Pinhole, Metal Housing

About This Product

Tired of trying to collimate your telescope in the dark, fighting bad seeing, and dropping tiny tools? This Astromania Artificial Star is a brilliant solution for daytime collimation. It's a tiny, super-bright LED behind a precise 50-micron pinhole that acts like a fake star. You set it up across a room (at least 20-30 feet away), dim the brightness to a comfortable level, and use it to align your mirrors perfectly. You look through the eyepiece and adjust until the diffraction rings are perfectly concentric. It's way more accurate than a real star because there's no atmospheric turbulence, and you can take your time in a well-lit room. It's built in a solid metal housing (not plastic!), has a standard 1/4\ tripod thread on the bottom, and runs on 2 AA batteries (not included). This tool is a total game-changer for Newtonian telescope owners, astro-imagers, or anyone who wants spot-on optics without the nighttime hassle. Get your collimation perfect once and for all.
