Lunt Front Mount 50mm Double Stack Solar Filter - LS50FHa

Presenting the Lunt LS50FHa Front Mount 50mm Double Stack Solar Filter: The LS50FHa is a 50mm aperture (no central obstruction) integrally tuned etalon expressly engineered for use on Lunt ED Refractors.

Lunt Solar is increasing its range of ED Telescopes, meeting the needs of both daytime and nighttime observations. 

This versatility allows for the utilization of a single telescope for both diurnal and nocturnal observations.

in addition, Lunt Solar provides a complete selection of dedicated Solar Telescopes to meet varying preferences and requirements.

Safety Note: It is crucial to use a matching Lunt Blocking Filter with a Lunt Solar front-mounted Filter as a safety requirement.

Users should select the blocking filter that aligns best with their system requirements.

Notably, a larger blocking filter is recommended for imaging to accommodate the camera's in-focus needs.

Switching between Day & Night Observation with the LS50FHa Solar Filter

The Lunt ED refractors are designed to be retrofitted with the LS50FHa Hydrogen-alpha Filter, enabling the use of ED telescopes during the day.

Notably, these filters are easily removable, allowing the Lunt ED scope to seamlessly transition for night observing purposes.

With an estimated bandpass of <0.70 Angstrom, the LS50FHa Solar Filter offers high-contrast views of both solar surface and edge details.

Importantly, the addition of an extra etalon system (double-stacking) further refines the bandpass to ~<0.50, facilitating enhanced resolution for viewing and imaging.

The LS50FHa, available by part number, caters to those seeking double-stacking capabilities or those already equipped with a Lunt blocking filter.

To stack two LS50FHa filters for better views, you don't need any extra parts. The right adapter plate will come with the filter, depending on your choice.
