With this filter LS60 telescopes and LS60FHa filter systems show even more details on the solar surface
- Suitable for LS60THa/MT telescopes & LS60FHa filter systems
- Reduces bandwidth to less than 0.55 Angstroms
- Significantly more contrast on the solar surface
- Thus, more details become visible on the sun
60mm H-alpha double-stack solar filter, for all LS60FHa filter-systems and LS60THa/LS60MT telescopes.
This double-stack Etalon is compatible to all Lunt Solar Systems LS60FHa filter-systems and LS60THa / LS60MT telescopes. Adding this additional double-stack Etalon system will reduce the bandwidth to ~<0.55 Angstrom (dependent upon used telescope). So you will have much more contrast and more details on the sun will be visible.
Without blocking filter! Only for use as double-stack filter, or together with an additional available blocking filter. If the filter is used only single stacked together with a optional blocking filter, then the bandwidth is <0.75 Angstrom.
