Description

The LS50THa solar telescope offers 50mm free aperture, 350mm focal length, and provides a bandwidth of <0.75 Angstrom. The telescope is fitted as standard with the air-pressure tuning system "Pressure-Tuner", the Etalon is safely installed inside the telescope. Prominences and surface detail can quickly be viewed spontaneously. This very portable system is an ideal travel companion for wherever you go.

A B600 blocking filter is installed inside the star diagonal. The B600 offers a larger field of view than the smaller B400 and is very good for visual solar observing. Focusing is achieved by a non-roting Helical focuser.

Please note that there is only a small back-focus at this telescope, therefore solar-imaging is very difficult. The LS50THa is designed for visual solar observing. We recommend for imaging the 60mm telescopes LS60THa.

Also double-stacking with a bandwidth of only <0.5 Angstrom is possible by using the additional available LUNT LS50C H-alpha Double-stack Solar Filter. This filter threads directly onto the LS50THa telescope. Double-stacking will provide much more contrast, and more details on the sun will become visible.

Features:

  • Aperture: 50mm
  • Focal Length: 350mm
  • Bandwidth: <0.75 Angstrom
  • Tuning: air-pressure tuning system "Pressure-Tuner"
  • Blocking Filter: B600
  • Non-rotating Helical focuser
  • Tube-ring with 1/4"-20 tapped base (standard thread for photo-tripods)

  • LS50THa H-alpha Solar Telescope
  • B600 Blocking Filter in star-diagonal
  • Pressure-Tuner
  • Tube ring with 1/4"-20 connection for mounting on photo-tripods
  • Non-rotating Helical focuser
  • Instruction manual
