More info

The LS80THa/B1200CPT H-alpha solar telescope is a precision aligned ED refractor with a fully un-obstructed 80 mm optical aperture and 560mm 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. The telescope is upgradeable with the new DSII double-stack system. The optional DSII is a internal double stack module with "Pressure Tuner", that provides a bandwidth <0.5 Angstrom. In addition to the "Pressure Tuner" has the DSII module the advantage that there are no more Energy-Rejection-Filter installed, unlike front-mounted double-stack filters. The ERF are allready in the telescope. Therefore the sun's image is brighter and prominences can be better observed than with conventional double-stack systems.
