Соларен филтър LUNT LS100FHa H-Alfa Double-stack

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.

Without blocking filter! Only for use as double-stack filter, or together with a additional available blocking filter. If the filter is used only single stacked together with a optional blocking filter, then the bandwidth is < 0.7 Angstrom.

The kit includes:

• LS100FHa solar filter
• Transport case
