About this product

Model:  lunt_ls152tha_dsii
Part Number:  0551595

Double-stack module for higher contrast and more details at the solar surface at LS152THa telescopes.

The LS152THa H-alpha solar telescopes can be double-stacked by using the internal DSII double-stack modules. This is a reasonably priced possibility for double-stacking. The DSII modules will reduce the bandwidth to <0.5 Angstroms. The DSII module is designed to provide enhanced surface detail, allowing for higher contrast views of the filaments and active regions.
The LS152THa/DSII module is designed only for using at LS152THa telescopes, it cannot be used at any other telescopes.
 
Internal double-stack filters can also produce reflections. Therefore, additional anti-reflection-filters will be offered for the smaller DSII modules for LS80THa and LS100THa. These anti-reflection-filters are still integrated as standard at the DSII modules for LS152THa telescopes.
 
Please note, if you use the DSII unit at a LS152THa, the back-focus will be 50mm less than without DSII unit. If you don't use the included quick-change-adapters, the back-focus will be only 24mm less.
