♦ Bandwidth <0,75 Angstrom

♦ Pressure Tuner adjustment

♦ non-rotating helical focuser

♦ 1.25`` and T2 connection

♦ Distance from the T2 thread to the focus: 35mm (fits nearly all eyepieces and all cameras with working distance 35mm or less from the connection thread to the sensor).


The LS50THa is a complete Solar Telescope with 50 mm aperture and 350 mm focal length. The internal etalon with a new pressure tuning system allows for
With the matched collimation lens set, the LS50THa is fully corrected for coma, astigmatism and de-centering aberrations and provides a full spherically corrected flat-field solar telescope.

With its compact dimensions, this Lunt is a good telescope for travelling, but also for a quick look at the sun while having a coffee.

Blocking filter is the B400, which is sufficient for the size of the solar image, but there is lottle scope left for improper tracking or focusing when using light mounts.

The star diagonal, in which the blocking filter is installed, is equipped as standard for 1.25`` eyepieces and with a T2 camera connection.

Fine adjustment is achieved with a helical focuser.

Adding an optional double-stack etalon system will reduce the bandwidth to
Important hint: In humid air, blocking filters might tarnish, so keep yours dry. You can get little packages of silica gel for reducing humidity even more. Put one and the filter into a small freezer bag and seal it.
