Lunt LS35THa Solar Telescope



The Lunt LS35THa Solar Telescope is a dedicated Hydrogen-alpha telescope and is the most compact 35mm etalon system currently available. An unobstructed, front mounted, 35mm etalon provides a bandpass of <0.75 Angstroms.

Prominences and some surface detail can quickly be viewed through this very portable single stack system. You can add it to an existing system or use it as a quick grab and go.

Because the LS35THa is small and compact it is ideally suited to being stacked side by side for Binocular viewing. The biggest OD of the LS35Tha is 62 mm (dew shield).

Both the normal LS35THa and the double stacked version with <0.55 Angstrom bandwidth are available as basic package or deluxe package.

The basic package telescopes are equipped with the B400 blocking filters designed for visual observation and come with adjustable scope clamshells. In addition the telescopes are equipped with a 1/4”-20 thread, so that the telescopes can easily be mounted on any photo tripod.
