The New LS35THa

The LS35THa dedicated Hydrogen-alpha telescope 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. Add it to an existing system or use 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).
