{"product_id":"daystar-filters-combo-quark-chromosphere-filter","title":"COMBO QUARK CHROMOSPHERE Filter","description":"\u003cp\u003eThe DayStar Combo Quark Chromosphere Filter is an innovative solar filter designed for amateur astronomers who want to explore the Sun's dynamic chromosphere in stunning detail. Ideal for use with SCTs, Maksutovs, and refractors operating between f\/15 and f\/30, this compact, all-in-one device transforms your telescope into a specialized solar observatory with minimal setup.\u003c\/p\u003e\r\n\u003cp\u003eBy integrating high-quality optical components, adapters, and a hydrogen-alpha filter into a single lightweight unit, it simplifies solar viewing without sacrificing performance. Whether you seek to observe subtle surface features or broader solar prominences, this filter offers a versatile solution tailored to your solar observing goals.\u003c\/p\u003e\r\n\u003ch6\u003eStreamlined Design for Easy Use\u003c\/h6\u003e\r\n\u003cp\u003eThe Combo Quark eliminates the need for multiple adapters by combining essential elements into one eyepiece-sized device. This reduces weight and complexity, allowing quick installation directly into your telescope diagonal. Its compact form factor encourages spontaneous solar sessions without cumbersome setup.\u003c\/p\u003e\r\n\u003ch6\u003eOptimized Optics for Enhanced Contrast\u003c\/h6\u003e\r\n\u003cp\u003eWith specialized anti-reflection coatings tuned to the hydrogen-alpha wavelength (656 nm) and internal baffles, the filter enhances solar contrast and clarity. This careful optical optimization reveals fine chromospheric details and subtle surface structures with remarkable sharpness.\u003c\/p\u003e\r\n\u003ch6\u003eFlexible Compatibility with Popular Telescopes\u003c\/h6\u003e\r\n\u003cp\u003eDesigned for SCTs, Maksutovs, and refractors within a specific focal ratio range, the filter supports a variety of telescope types. Users must incorporate an appropriate Energy Rejection Filter (ERF) for safe operation, especially on SCT and Maksutov scopes, ensuring protection against heat buildup and maintaining optimal image quality.\u003c\/p\u003e\r\n\u003ch6\u003ePrecision Tuning and User Control\u003c\/h6\u003e\r\n\u003cp\u003eA convenient tuning knob allows precise adjustment of the filter's passband, enabling observers to fine-tune views of the solar chromosphere. Detents at small increments provide tactile feedback for accurate positioning, while LED indicators communicate power and readiness status during use.\u003c\/p\u003e\r\n\u003ch6\u003ePortability and Power Efficiency\u003c\/h6\u003e\r\n\u003cp\u003ePowered via USB with a low current draw, the Combo Quark can operate off a compact battery pack for extended periods, making it suitable for field observations. It ships in a protective twist-case to keep the filter safe and dust-free between sessions.\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\u003eFront Nosepiece\u003c\/th\u003e\r\n\u003ctd\u003e1.25\" male with safety indent slot\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eOff-Axis Adapter\u003c\/th\u003e\r\n\u003ctd\u003e2° off-axis 1.25\" adapter included\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eOutput\u003c\/th\u003e\r\n\u003ctd\u003eStandard 1.25\" female eyepiece drawtube\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eOptional Accessories\u003c\/th\u003e\r\n\u003ctd\u003e2\" eyepiece holder, T-mount, C-mount adapters\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eEyepiece Protection\u003c\/th\u003e\r\n\u003ctd\u003eBrass compression ring\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\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003ePower Supply\u003c\/th\u003e\r\n\u003ctd\u003e90-240VAC wall adapter with international plugs\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eTuning Range\u003c\/th\u003e\r\n\u003ctd\u003eWing shifting ±0.5Å with 0.1Å detents\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eIndicators\u003c\/th\u003e\r\n\u003ctd\u003eLED for power, warming, ready, fault\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eFilter Aperture\u003c\/th\u003e\r\n\u003ctd\u003e25mm blocking filter, 21mm clear aperture\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eCompatibility\u003c\/th\u003e\r\n\u003ctd\u003eF\/15 to F\/30 refractors, Maksutovs, SCTs with off-axis ERF\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eViewing Capability\u003c\/th\u003e\r\n\u003ctd\u003eFull solar disk on refractors up to ~1800mm focal length\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eIncluded Case\u003c\/th\u003e\r\n\u003ctd\u003eProtective twist-case for storage\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eWarranty\u003c\/th\u003e\r\n\u003ctd\u003e5 years (US)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eOptional Battery Pack\u003c\/th\u003e\r\n\u003ctd\u003e8-hour portable power available\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\/1-04-001-0046-01.pdf?v=1766964500\" target=\"_blank\" rel=\"noopener\"\u003e\u003cspan class=\"doc-icon\" aria-hidden=\"true\"\u003e📘\u003c\/span\u003e COMBO QUARK CHROMOSPHERE Filter\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DayStar Filters","offers":[{"title":"Default Title","offer_id":45992299856071,"sku":"1-04-001-0046","price":1295.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/9575\/6487\/files\/1-04-001-0046-01.jpg?v=1766964505","url":"https:\/\/snowflakeskies.com\/products\/daystar-filters-combo-quark-chromosphere-filter","provider":"Snowflake Skies","version":"1.0","type":"link"}
