LS100FHa — 100mm Front-Mount H-Alpha Solar Filter A 0.45Å tilt-tuned etalon for two purposes: double-stack upgrade for existing Lunt 100mm systems, or standalone H-alpha filter for customer-supplied refractors.
Now with new-generation etalons — every unit individually tested on Lunt's precision metrology equipment. Every specification is verified, not estimated.
The LS100FHa is a 100mm aperture front-mounted tilt-tuned H-alpha filter with a Root 3 non-centralized obstruction design and a verified bandpass of 0.45Å. It serves two distinct purposes — as a double-stack etalon for existing Lunt 100mm solar systems, or as a standalone H-alpha solar filter for a customer-supplied refractor.
As a double-stack filter: The LS100FHa places its 0.45Å tilt-tuned etalon in series with an existing Lunt 100mm etalon system, reducing combined system bandpass to <0.29Å. It is offered without a blocking filter for this purpose or for those who already own a compatible Lunt blocking filter.
As a standalone H-alpha filter for customer refractors: The LS100FHa retrofits a compatible customer-supplied refractor for daytime solar observation via the appropriate adapter. An adapter for refractors up to 102mm is included. For refractors over 102mm contact [email protected] for adapter pricing and availability. The filter is easily removable for night observing. A Lunt blocking filter must be used at all times — this is a safety requirement.
If you are looking for a complete standalone package including a blocking filter and adapter, see Lunt's complete front-mounted filter packages at luntsolarsystems.com/collections/front-mounted-etalon-systems
Important: Please include the telescope model you are connecting the LS100FHa to in the notes section of your order so the correct adapter can be included.
