Coronado Personal Solar Telescope 1A Bandwidth - PST
The Coronado PST is a game-changing solar telescope. It’s the world’s most popular way to safely observe our closest star in Hydrogen-alpha light. Before the Coronado PST, observers could outfit their nighttime telescope with a suitable solar filter to view sunspots in white light, or they could spend thousands on dedicated solar scopes that display the Sun in brilliant red Hydrogen-alpha with stunning surface detail. With the PST, everyone can experience the magic of H-alpha solar observing, but at a fraction of the cost! This 40mm telescope features a bandpass of less than 1 angstrom, allowing only a tiny amount of H-alpha light to pass through to the eyepiece. A high quality milled aluminum—not plastic—housing prevents heat buildup inside the optical tube.
