Descrizione
Complete H-alpha solar telescope with 80mm aperture, < 0.7 Angstrom bandwidth, advanced air-pressure tuning system, B1200 blocking-filter, and Feather-Touch focuser.
The LS80THa/B1200FTPT is a complete telescope for observing the sun in H-alpha, a precision aligned ED refractor with 80mm aperture (no central obstruction) and 560mm 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 2' Starlight-Instruments Feather-Touch focuser with 1.5' travel and 10:1 reduction.
Blocking-filter is the B1200. The B1200 is good for visual solar observing. Also solar imaging is possible by cameras with small or middle sized CCD chip. We recommend a LS80THa with B1800 blocking-filter by using cameras with large 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.
The telescope is upgradeable with the additional available DSII double-stack system. The optional DSII system is a internal double stack module with 'Pressure Tuner', that provides a bandwidth < 0.5 Angstrom. More details on the solar surface will become visible by reducing the bandwidth.
