Lunt Solar Systems' LS50THa 50mm f/7 Refractor Solar Telescope is ideally suited for beginner solar observers or as a grab-and-go option for fast sessions. It features a 50mm objective lens and an internal etalon with a <0.75 Angstrom bandpass. The scope is offered here with a 6mm blocking filter in a star diagonal configuration. It fits in the helical focuser and accepts 1.25" eyepieces for visual observation.

Integrating the etalon into the optical path reduces interference and distortion which can occur with externally mounted filters. True Doppler Tuning allows for a shift into and away from the user for a richer depth of field. While looking at a filament at the center of the Sun, the user has the ability to Doppler shift from the base of the filament to the tip, following the filament through its structure toward and away from them, allowing for enhanced visual and imaging capability.

Complementing the optical performance and technologies is a 1.25" helical focuser. This type of focuser has a rotating collar around the filter holder in place of the focusing tube which reduces the overall length of the telescope while maintaining the ability to achieve a fine focus. This solar scope is offered here without a mount or tripod, but is outfitted with a mounting base that has a 1/4"-20 thread for attaching it to most tripods or compatible mounts.
