Ideal for both visual observation and imaging, this specialized instrument reveals solar phenomena far beyond the reach of conventional white light filters, capturing features such as prominences, sunspots, and plasma filaments with striking clarity.\u003c\/p\u003e\r\n\u003cp\u003eEngineered to meet the needs of serious solar observers, the Heliostar combines advanced optical technology with user-friendly features, making it an excellent choice for anyone seeking safe and detailed views of our nearest star.\u003c\/p\u003e\r\n\u003ch6\u003eExceptional Hydrogen-alpha Imaging\u003c\/h6\u003e\r\n\u003cp\u003eThis telescope isolates the specific 656.3 nm wavelength of hydrogen-alpha light, unveiling the Sun's chromosphere and its intricate activity. Observers can witness solar prominences, spicules, and active regions with enhanced contrast, providing a vivid and engaging solar experience.\u003c\/p\u003e\r\n\u003ch6\u003eAdvanced Etalon Filter Technology\u003c\/h6\u003e\r\n\u003cp\u003eEquipped with the innovative Solis Etalon system, the Heliostar achieves a narrow bandpass below 0.55Å, delivering double-stack level performance without the complexity or brightness loss typically associated with dual etalon setups. This streamlined approach allows for detailed solar observations with simpler operation.\u003c\/p\u003e\r\n\u003ch6\u003ePrecision Tuning with Trifid Tuner\u003c\/h6\u003e\r\n\u003cp\u003eThe integrated Trifid Tuner applies controlled pressure to the etalon plates, enabling fine adjustments to the transmitted wavelength. This feature ensures optimal alignment with solar emission lines, accommodating subtle shifts caused by atmospheric conditions or solar dynamics.\u003c\/p\u003e\r\n\u003ch6\u003eRobust Optical Design\u003c\/h6\u003e\r\n\u003cp\u003eFeaturing a 76mm aperture and 630mm focal length with an achromatic doublet lens, the telescope provides sharp, high-resolution views. Its fully multicoated hydrogen-alpha lens enhances light transmission and contrast, while a dual-speed Crayford focuser allows for smooth and precise focusing.\u003c\/p\u003e\r\n\u003ch6\u003eComprehensive Accessory Set\u003c\/h6\u003e\r\n\u003cp\u003eReady for immediate use, the Heliostar includes mounting rings, a V-style dovetail, a dedicated solar finder, a 20mm 70° eyepiece, an 11.5mm blocking filter in a specialized diagonal for safety, a clip-on sunshade, and a camera phone adapter. All components are housed in a durable carrying case for convenient transport and setup.\u003c\/p\u003e\r\n\u003ch6\u003eSafety and Reliability\u003c\/h6\u003e\r\n\u003cp\u003eEach telescope is individually tested to meet rigorous ISO safety standards for solar observation. The included blocking filter and dedicated diagonal ensure safe viewing, emphasizing the importance of proper handling when observing the Sun.\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\u003eOptical Design\u003c\/th\u003e\r\n\u003ctd\u003eAchromatic doublet\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eAperture\u003c\/th\u003e\r\n\u003ctd\u003e76 mm\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eFocal Length\u003c\/th\u003e\r\n\u003ctd\u003e630 mm\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\r\n\u003ctd\u003ef\/8.3\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eBandpass\u003c\/th\u003e\r\n\u003ctd\u003e\u0026lt;0.55 Å\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eLens Coating\u003c\/th\u003e\r\n\u003ctd\u003eH-alpha fully multicoated\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eFocuser Type\u003c\/th\u003e\r\n\u003ctd\u003e2-inch dual-speed Crayford\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eBlocking Filter Size\u003c\/th\u003e\r\n\u003ctd\u003e11.5 mm diagonal (1.25\")\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eWeight\u003c\/th\u003e\r\n\u003ctd\u003e8.4 lbs\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eIncluded Accessories\u003c\/th\u003e\r\n\u003ctd\u003eOTA, mounting rings, V-style dovetail, solar finder, 20mm 70° 1.25\" eyepiece, 11.5mm blocking filter diagonal, clip-on sunshade, camera phone adapter, hard-shell carrying case\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003c\/tbody\u003e\r\n\u003c\/table\u003e","brand":"Sky-Watcher","offers":[{"title":"Default Title","offer_id":45975748411591,"sku":"1-19-002-0001","price":3395.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/9575\/6487\/files\/1-19-002-0001-01.jpg?v=1766369667","url":"https:\/\/snowflakeskies.com\/products\/sky-watcher-heliostar-76-h-alpha-telescope","provider":"Snowflake Skies","version":"1.0","type":"link"}
