50mm Secondary Front Mounted (Compact) Filter for 50mm Telescope

50mm Double Stack Filter

General Features:

The specially-designed Lunt Solar Systems LS50C is a compact double stack filter made especially for the Lunt 50mm h-alpha Solar Telescope.

The 50C lowers the bandpass of the 50mm Solar Telescope to less than <0.5 Angstroms.
The 50C contains a 50mm UNOBSTRUCTED Etalon.
The 50C simply screws into the front of the 50mm Solar Telescope. (no adapters required)
The filter assembly has an integral ERF (Energy Rejection Filter) which removes 100% of harmful UV and a significant portion of the IR radiation.
The 50C is a tilt tuned filter. Before adding the 50C to your 50mm Solar Telescope you must tune the internal pressure tuned filter for maximum detail prior to installing the secondary filter. Once the secondary filter is installed turn the small tilt wheel at the base while looking through the telescope at low to medium magnification. Tune for best detail. Some very minor adjustments can then be done to the internal pressure tuned filter via small rotation of the PT knob to optimize the details of interest.
