The Coronado PST 0.5A is a specialized hydrogen-alpha solar telescope designed for safe, high-contrast viewing of solar prominences, flares, filaments, and surface details. This compact 40mm f/10 refractor uses dual etalon filters (internal and external) to achieve an exceptionally narrow 0.5 Angstrom bandpass, revealing intricate solar chromosphere activity that wider-bandpass systems cannot match. Weighing only 3 lbs and measuring 15 inches long, it requires minimal mounting support and includes a built-in solar viewfinder and RichView tuning system for optimal contrast adjustment. The telescope is fully ISO 12312-2 certified for safe solar observation and makes sub-angstrom H-alpha viewing accessible to amateur astronomers and solar astrophotographers.
