Quick Overview
- LS50FHa solar filter front-mounted non-obstructed hydrogen-alpha filter for use on Lunt ED Telescopes or Double Stacking an existing Lunt Solar System
- Connect the Lunt LS50FHa to the Lunt ED telescope with the adapter (Included), or use it to double-stack on an existing Lunt 50mm filter for a ~<0.5A band pass
- Choose the appropriate LS50FHa and blocking filter to match your Visual and/or Imaging requirements.
Product Details
The Lunt LS50FHa is a 50mm aperture (no central obstruction) integrally tuned etalon for use on Lunt's 60mm telescopes (only). They are easily removable so that the scope can continue to be used for night observing.
Because the LS50FHa has an estimated bandpass of <0.70 Angstroms it is capable of providing high contrast views of both surface and edge detail. Adding an additional etalon (double-stacking) will reduce the bandpass to ~<0.50 (dependent upon scope) allowing for higher resolution viewing and/or imaging. The part number LS50FHa is offered for this purpose or for those who already have a Lunt blocking filter. A Lunt blocking filter must be used with Lunt Ha filters at all times.
Note that this item cannot be used with the Lunt LS50THa solar telescope. For that, please see Lunt's Compact Double Stack Filter # LS50C.
