LUNT LS130THa/DSII doublestack module for LS130THa
?NEW, available presumably from March 2020

Double-stack module for more contrast and details on the solar surface at LS130THa telescopes.

At the LS130THa H-alpha solar telescopes double-stacking is possible with these internal DSII double-stack modules. The DSII modules reduce the bandwidth to <0.5 Angstroms. The DSII modules are designed to show the surface details of the Sun better, the contrast is significantly increased and thus filaments, active regions and other surface details are much more visible.
Like the LS130THa telescope, the DSII Double-Stack module is tuned via the innovative Pressure-Tuner system, and the sensitive Etalon is well protected inside the telescope.

The LS130THa/DSII module is designed exclusively for use in the LS130THa telescope, it cannot be used at other telescopes.

FEATURES

• Bandwidth: <0.5 Angstrom
• Tuning: air-pressure tuning system

SCOPE OF DELIVERY
