Lunt LS50THa Hydrogen-alpha Solar Telescope LS50THa/B400PT

The New Lunt Solar LS50THa Hydrogen-alpha Solar Telescope LS50THa/B400PT 

Lunt Solar Systems is excited to announce our new 50mm Pressure Tuned dedicated Hydrogen-alpha telescope, the LS50THa! This new solar telescope is a refractor-based system with a 50mm aperture and an internal-mounted etalon with Pressure Tuner adjustment.  This system allows for a  <0.75 Angstrom band pass.

Specifications: (single stacked)

Type: Single Interference Etalon
Tuning: Internal Pressure Tune (Doppler True Tuning)
Aperture: 50mm
Focal Length: 350mm
F Ratio: F7
Bandpass: <0.75 Angstroms @ 656nm
Focuser: Helical Focuser
Mounting: Integrated clamshell style with 1/4-20 tapped base
Color: Pearl White with Black and Red accents
Diagonal: B400 Blocking Filter 

An optional and especially designed LS50C Compact double stack filter is also available at additional cost.
The LS50C allows you to lower the bandpass to <0.5 Angstroms, which gives you much more surface detail.  The filter threads directly onto the LS50THa.
