Lunt 60mm H-alpha Telescope, B600 Blocking Filter

These telescopes with their 60 mm aperture and 500 mm focal length provide a very detailed resolution for observing and imaging the sun. However, with a weight of approximately 3.5 kg the telescopes can easily be carried by most photo tripods. The tube rings of these telescopes are fitted with a 1/4”-20 thread for mounting it on such tripods. The sensitive Etalon systems are well protected in the telescope tube installed and provide a bandwidth of <0.75 Angstrom. A integrated matched collimation lens set fully corrects on axis coma, astigmatism, and de-centering aberrations and provide a full spherically corrected flat-field solar telescope.

Blocking filter is the B600. 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 focuser with 10:1 reduction.

Normally these telescopes are equipped with a 2” Crayford focuser with 10:1 reduction. They are also available with the legendary Starlight Instruments Feather-Touch focuser, one of the best focuser in the world. Certainly also with 10:1 reduction.

All versions come with a robust aluminum-case as part of the standard package.
