It lowers the bandpass of the system from \u0026lt;0.35 Angstroms to \u0026lt;0.22 Angstroms. This will significantly make the surface features on the Sun “pop”! The Lunt 130 mm and 152 mm can be internally double-stacked at the time of purchase or anytime thereafter and does not need to be returned to the factory for double-stacking.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eSubsequently, add the DSII internal double stack module to make it a double stack unit later. This will make it more affordable to purchase our best solar telescope and still have room for upgrades. Once you upgrade your Lunt LS130MT with the LFPT internal double stack module, you will be able to see the finer details on the Sun that were not previously visible.\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAdd an internal double-stacking module to a Lunt 130 mm or Lunt 152mmtelescope for a lowered bandpass of \u0026lt;0.35 Angstroms!\u003c\/li\u003e\n\u003cli\u003eThe LFPT includes a pressure tuner for true Doppler tuning.\u003c\/li\u003e\n\u003cli\u003eAdd it yourself to your own Lunt 130 mm or Lunt 152m mm Telescope, no trip back to the factory required!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cp\u003eLunt Double Stack Filter for LS130MT \u0026amp; LS152THa Telescopes\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eWarranty \u0026amp; Manuals\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003eLunt 5-Year Warranty\u003c\/p\u003e","brand":"Lunt","offers":[{"title":"Double Stack for LS130MT","offer_id":44179557056741,"sku":"LS-DSII\/LFPT\/LS130MT","price":4193.0,"currency_code":"CAD","in_stock":true},{"title":"Double Stack for LS152THa","offer_id":44179557089509,"sku":"LS-DSII\/LFPT\/LS152THa","price":4193.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/Lunt-Double-Stack-Filter-LS130MT-LS152THa-Telescopes.webp?v=1777045472","url":"https:\/\/istronomyplus.com\/products\/lunt-internal-double-stack-module-for-ls130tha-dsii-ls130tha","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
