Lunt Solar Systems Double-Stack Filters DSII for Solar Telescope LS130MT Ha (69162)

The Lunt Solar Systems DSII Double-Stack Filter is an advanced accessory designed specifically for the LS130MT H-alpha solar telescope. This internal double-stack module significantly reduces the filter’s bandpass, increasing contrast and revealing much finer details on the Sun’s surface, such as filaments, active regions, and other solar phenomena. The DSII module uses an innovative air-pressure tuning system (Pressure Tuner) for precise adjustment and is safely housed inside the telescope. This module is intended exclusively for the LS130MT and cannot be used with other models.

By adding the DSII double-stack module to the LS130MT, users can achieve a substantial improvement in solar surface detail and contrast, making it ideal for experienced solar observers who want to explore the Sun’s features with maximum clarity.
