FEATURES
This double-stack Etalon is compatible to all Lunt Solar Systems LS100FHa filter-systems.
Also the LS100THa H-alpha solar telescopes can be very easily double-stacked by using this 100mm double-stack filter. This combination offers high quality double-stacking to the observer.
Adding this additional double-stack Etalon system will reduce the bandwidth to ~<0.55 Angstrom. So you will have much more contrast and more details on the sun will be visible.
