{"product_id":"daystar-filters-magnesium-quark-filter","title":"MAGNESIUM Quark filter","description":"\u003cp\u003eThe Magnesium I b2 Line Quark is a precision solar filter designed for amateur astronomers and astrophotographers using refractor telescopes. It reveals the sun's magnetic activity at a bright green wavelength where the human eye is most sensitive, delivering clearer and more detailed views of solar phenomena such as plages and chromospheric mottling.\u003c\/p\u003e\r\n\u003cp\u003eEngineered for simplicity and performance, this compact filter integrates all necessary optical components into a single, lightweight device that fits directly into your telescope's diagonal. It is ideal for observers seeking to explore magnetic structures and high-energy solar regions with short exposure times and enhanced contrast.\u003c\/p\u003e\r\n\u003ch6\u003eOptimized Optical Design\u003c\/h6\u003e\r\n\u003cp\u003eThe filter incorporates a custom 4.2X telecentric barlow lens that ensures a flat field and sharp images across the viewing area. Anti-reflection coatings are specifically tailored for the 5172.8Å magnesium wavelength, maximizing light transmission and contrast.\u003c\/p\u003e\r\n\u003ch6\u003eMagnetic Solar Detail\u003c\/h6\u003e\r\n\u003cp\u003eObservations at this wavelength enable the detection of Zeeman splitting, a spectral signature indicating magnetized solar regions. This allows users to study the sun's complex magnetic structures and dynamic chromospheric features with exceptional clarity.\u003c\/p\u003e\r\n\u003ch6\u003eEase of Use\u003c\/h6\u003e\r\n\u003cp\u003eDesigned for F\/4 to F\/8 refractor telescopes, the filter requires no additional adapters or complex setup. Simply insert it into your diagonal, attach an eyepiece, and begin observing. The device comes with both 1.25\" and 2\" eyepiece snouts to match your equipment.\u003c\/p\u003e\r\n\u003ch6\u003eCompact and Efficient\u003c\/h6\u003e\r\n\u003cp\u003eThe streamlined design reduces weight and eliminates unnecessary parts, making it portable and convenient. Its low power consumption allows operation throughout the day using an optional small battery pack, enhancing field usability.\u003c\/p\u003e\r\n\u003ch6\u003eEnhanced Contrast and Safety\u003c\/h6\u003e\r\n\u003cp\u003eIntegrated baffles suppress stray light to boost image contrast, while the filter requires pairing with a specific energy rejection filter for safe solar viewing. This ensures your observations are both spectacular and secure.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable class=\"spec-table\"\u003e\r\n\u003ctbody\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eManufacturer Part Number\u003c\/th\u003e\r\n\u003ctd\u003eDSZMG\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eCentral Wavelength\u003c\/th\u003e\r\n\u003ctd\u003e5172.8Å\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eApproximate Bandpass (FWHM)\u003c\/th\u003e\r\n\u003ctd\u003e0.3–0.5Å\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eCompatible Focal Ratios\u003c\/th\u003e\r\n\u003ctd\u003eF\/4 to F\/8 refractors\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eTelecentric Barlow Magnification\u003c\/th\u003e\r\n\u003ctd\u003e4.2X\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eFilter Shape\u003c\/th\u003e\r\n\u003ctd\u003eRound\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eEyepiece Sizes Included\u003c\/th\u003e\r\n\u003ctd\u003e1.25\" and 2.0\" snouts\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eFilter Aperture\u003c\/th\u003e\r\n\u003ctd\u003e21mm clear aperture\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eBlocking Filter Diameter\u003c\/th\u003e\r\n\u003ctd\u003e12mm\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003ePower Requirements\u003c\/th\u003e\r\n\u003ctd\u003eUSB 5V, 1.5A (includes 90-240VAC adapter)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eOptional Battery Pack\u003c\/th\u003e\r\n\u003ctd\u003eAvailable (approx. 8-hour operation)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eWeight\u003c\/th\u003e\r\n\u003ctd\u003eLightweight, eyepiece-sized device\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eWarranty\u003c\/th\u003e\r\n\u003ctd\u003e5 years\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003c\/tbody\u003e\r\n\u003c\/table\u003e\n\n\u003ch2\u003eManuals \u0026amp; Documents\u003c\/h2\u003e\u003ch3\u003eManual\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0736\/9575\/6487\/files\/1-04-001-0049-01.pdf?v=1766965756\" target=\"_blank\" rel=\"noopener\"\u003e\u003cspan class=\"doc-icon\" aria-hidden=\"true\"\u003e📘\u003c\/span\u003e MAGNESIUM Quark filter\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DayStar Filters","offers":[{"title":"Default Title","offer_id":45992306868423,"sku":"1-04-001-0049","price":1495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/9575\/6487\/files\/1-04-001-0049-01.jpg?v=1766965762","url":"https:\/\/snowflakeskies.com\/products\/daystar-filters-magnesium-quark-filter","provider":"Snowflake Skies","version":"1.0","type":"link"}
