It is offered without a blocking filter for this purpose or for those who already own a compatible Lunt blocking filter.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eAs a standalone H-alpha filter for customer refractors:\u003c\/strong\u003e 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 sales@luntsolarsystems.com 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.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eModel: LS100FHa\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eOptical Aperture: 100mm — Root 3 non-centralized obstruction\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eTuning: Tilt-tuned\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eSingle Etalon Bandpass: 0.45Å — individually verified\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDS Combined Bandpass: \u0026lt;0.29Å when used to double-stack an existing Lunt 100mm system\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCompatible With: Existing Lunt 100mm systems (DS); customer refractors up to 102mm (standalone, adapter included); larger refractors — contact Lunt\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eBlocking Filter Required: Yes — sold separately\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eWeight: ~8 lbs\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eStorage: Aluminum hard case with fitted foam\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Starizona","offers":[{"title":"Default Title","offer_id":48746665345281,"sku":"LS100FHa","price":4495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0327\/2569\/6648\/files\/LS100FHav_2.jpg?v=1778110506","url":"https:\/\/starizona.com\/products\/lunt-ls100fha-solar-filter","provider":"Starizona","version":"1.0","type":"link"}
