The Lunt LS50FHa Solar Filter is a 50 mm aperture (no central obstruction) integrally tuned etalon for use on Lunt ED Refractors.

Description

Lunt Solar will be introducing a larger selection of ED Telescopes that will meet your Solar needs for Daytime observing and meet the additional requirements of Nighttime observing. In this way you can use one scope for day and night.

Lunt Solar also offer a full line of dedicated Solar Telescopes.

You MUST use a matching Lunt Blocking Filter with a Lunt Solar front mounted Filter (this is a safety requirement). For this reason choose the blocking filter that best suits your requirements for the system. It’s important to realize that a larger blocking filter is recommended for imaging due to the need for in-focus of the camera.

Removing the LS50FHa Solar Filter for night use
The Lunt ED refractors are designed to retrofitted with the LS50FHa Hydrogen-alpha Filter. In this way you can use the ED telescopes during the day. Notably, they are easily removable so that the Lunt ED scope can continue to be used for night observing.

Because the LS50FHa Solar Filter has an estimated bandpass of <0.70 Angstrom it is capable of providing high contrast views of both surface and edge detail. Significantly, adding an additional etalon system (double-stacking) will reduce the bandpass to ~<0.50. Allowing for higher resolution viewing and/or imaging. In addition, the part number LS50FHa is offered for this purpose or for those who already have a Lunt blocking filter.
