Lunt LS80THa/B1800FTPT H-alpha Solar Telescope

Lunt LS80THa/B1800FTPT H-alpha Solar Telescope

This system's Blocking Filter is the B1800, which provides a smaller vignetting circle for imaging with larger format cameras. The star diagonal in which the blocking filter is mounted is equipped to take 1.25" eyepieces and also sports a T2 camera connection.

Fine adjustment is achieved with the excellent Starlight Instruments high-end focuser Feather Touch, featuring 10:1 dual fine and course focusing controls.

Aperture: 80 mm (ED refractor, unobstructed)
Focal length: 560 mm
Bandwidth: internal Etalon with <0,7 Angstrom
Tuning: air-pressure tuning system
Blocking Filter: B1800 with 1.25" and T2 connection
Focuser: Starlight Instruments Feather Touch with 10:1 reduction
Weight: 4 kg

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 already in the telescope. Therefore the sun's image is brighter and prominences can be better observed than with conventional double-stack systems.
