Lunt Solar 50mm LS50THa Solar Telescope - B400 Blocking Filter & Pressure Tuner - LS50THa/B400PT

The Lunt LS50T H-Alpha Solar Telescope is a refractor-based system with a 50mm aperture and an internal-mounted etalon with Pressure Tuner adjustment.

The Lunt LS50T H-Alpha Solar Telescope is without a doubt the best value available in an entry level hydrogen-alpha wavelength solar telescope. It combines 50mm of aperture with Lunt''s innovative pressure tuning system. The pressure tuner allows for far greater granularity in the bandpass adjustment which allows you to fine tune the instrument for maximum detail. Shown with optional Sol-Searcher Finder.
