The recently announced LS50THa/PT Complete H-Alpha Solar Telescope is again a great and welcomed idea from Lunt and is now available from our UK stock!

This H-alpha telescope comes with 50mm aperture and <0.75 Angstrom bandwidth. An affordable complete telescope for viewing the sun in H-alpha light.

The LS50THa is a complete Solar Telescope with 50mm clear aperture and 350mm focal length. An internal etalon with tune adjustment allows for a <0.75 Angstrom bandwidth.

In this version a B400 blocking filter is being used.



The refractor based telescopes will provide:

- 50mm free aperture (no central obstruction)

- 350mm focal length

- internal Etalon with air-pressure tuning system “Pressure Tuner”

- bandwidth <0.75 Angstrom

- non-rotating Helical focuser

- clamshell with 1/4-20 tapped base (standard thread for photo-tripods)


Also double-stacking with a bandwidth of only <0.5 Angstrom will be possible. Therefore Lunt Solar Systems has especially designed a new LS50C double-stack filter in compact housing. The filter threads directly onto the LS50THa telescopes and gives much more contrast on the surface detail at the sun.

Of course, also the standard double-stack filters LS50FHa and LS60FHa can be used at the LS50THa telescopes. Therefore an adapter LS150/50 is also available separately...
