Lunt LS60THA/B600FTPT H-alpha solar telescope

LUNT LS60THa/B600FTPT H-alpha solar telescope

Complete H-alpha solar telescope with 60mm aperture, <0.7 Angstrom bandwidth, advanced air-pressure tuning system, B600 blocking-filter, and Feather-Touch focuser.

The LS60THa/B600FTPT is a complete telescope for observing the sun in H-alpha, with 60mm aperture (no central obstruction) and 500mm focal length. An internal Etalon with advanced air-pressure tuning system “Pressure-Tuner” provides <0.7 Angstrom bandwidth. This “Pressure Tuner” system allows a more accurate Etalon adjustment than other systems. The “Pressure Tuner” system adapted the Etalon to varying altitudes and atmospheric pressures for always optimal performance. The Etalon is installed safely inside the telescope-tube.
Fine adjustment is achieved by a Starlight-Instruments 2" Feather-Touch focuser with 1.5" travel and 10:1 reduction.

Blocking-filter is the B600. The B600 is good for visual solar observing. Also solar imaging is possible by cameras with small CCD chip. We recommend a LS60THa with B1200 blocking-filter by using cameras with middle or large sized CCD chips.
The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25" eyepieces and with a T2 camera connection.
