Lunt 80mm H-alpha Telescope, B1200, Crayford focuser and Pressure Tuner
The LS80THa is a complete Solar Telescope, a precision aligned ED refractor with a fully un-obstructed 80 mm optical aperture and 560 mm focal length. An internal etalon with new air-pressure tuning 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 B1200. 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 Crayford style focuser with 10:1 reduction.Stock No: 0551307
