The specially-designed Lunt Solar Systems LS50C is a compact double stack filter. Notably, it was made especially for the Lunt LS50THa H-alpha Solar Telescope. The LS50C lowers the bandpass of the LS50THa to less than <0.5 Angstroms giving you truly stellar, professional quality views. The LS50C gives you the option of upgrading your single-stack LS50THa to a double stack solar telescope.  Furthermore, you can install the upgrade yourself. Because the LS50THa screws on the the front of your LS50THa, so you won’t have to send it back to our factory.

By adding a double stack filter to your solar telescope, you will be able to see a crisp, clear image of the surface prominence’s of the Sun.  This will give you the images that you need for research or just viewing enjoyment.

Please Note: This filter cannot be used without a blocking filter.
