The LS100THa is a complete H-alpha Solar Telescope with 100mm aperture (no obstruction!) and 800mm focal length. An internal etalon with new air-pressure tuning system adjustment allows for a <0.7 Angstrom bandwidth. This "Pressure Tuner" system allows a better Etalon adjustment than other systems. The ?Pressure Tuner? system adapted the Etalon to varying altitudes and atmospheric pressures for always optimal performance.
Blocking filter is the B1800, that is well suited for imaging. The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25" eyepieces and with a T2 camera connection. Focusing is achieved with a high precision Starlight Instruments 2" Feather Touch focuser with the a 10:1 reduction as standard equipment.
Addionally the system may also be purchased with the optional available 100mm external, front mounted Double Stack Etalon LS100FHa for a bandwidth of <0.5 Angstrom.
