Lunt LS50THa 50mm Pressure Tuned H-Alpha Telescope
50mm solar telescope for observing prominences & more with the advanced Pressure-Tuner system
The LS50THa solar telescope offers 50 mm free aperture, 350 mm 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 B400 or B600 blocking filter is installed inside the star diagonal. The B400 is good for visual observing. 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-rotating 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 of the LS60MT series.
Also double-stacking with a bandwidth of only <0.5 Angstrom is possible by using the additional available LS50C filter (0550210). This filter threads directly onto the LS50THa telescope. Double-stacking will provide much more contrast, and more details on the sun will become visible.
LS50THa Package Features:
- A Narrow Band Hydrogen-alpha Dedicated System.
- A refractor-based system with a 50 mm front objective.
- An internal Etalon with a pressure tuner allows for <0.75 Angstrom bandpass.
- The system includes the clamshell with threaded holes for mounting and dust caps.
All Lunt Solar Systems h-alpha telescopes require a Lunt Blocking Filter!
Add the specially-designed LS50C compact double stack filter (sold separately) and lower the bandpass to <0.5 Angstroms for more surface detail. The LS50C threads directly onto the LS50THa for instant gratification!
