Lunt 50mm Ha Etalon Solar Filter

Highlights:

• LS50FHa solar filter front-mounted non-obstructed hydrogen-alpha filter for use on Lunt ED Telescopes or Double Stacking an existing Lunt Solar System!
• Accommodates LS60THA and LS60MT Telescopes without need for adapter
• Connect the Lunt LS50FHa to an appropriately sized refractor of your choosing, or use it to double-stack on an existing Lunt 60mm Telescopes for a ~<0.5A band pass!
• Choose the appropriate LS50FHa and blocking filter to match your Visual and/or Imaging requirements.

DSII Requirements: No adapter is needed to add one LS50FHa to another LS50FHa for double-stacking. The LS50FHa attaches natively to Lunt 60mm Model Telescopes (Lunt LS60THa and Lunt 60mm Universal Telescope).

The Lunt LS50FHa Solar Filter is a 50 mm aperture (no central obstruction) integrally tuned etalon.

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.

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.
