It is tuned specifically for viewing chromosphere details. The chromosphere's surface structure behaves differently in active regions than quiet areas, where magnetic field lines are stronger, so viewing this portion of the sun provides a constantly-changing observational.\u003c\/p\u003e \u003cp\u003eWhile there are no OTA aperture limitations, Daystar recommends the use of front-mount aperture-reducing off-axis energy rejection filters. The filter is powered via a micro-USB port, and Daystar includes a power cord and an AC adapter to meet the high-power requirements of 5 VDC 1.5A. To enable its use at home and abroad, a set of international outlet plugs is provided with adapters for the US, UK, EU, and Australia.\u003c\/p\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdl\u003e \u003cdt\u003eFilter Properties\u003c\/dt\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003eHydrogen-alpha bandpass\u003c\/li\u003e \u003cli\u003eIntegrated 25mm blocking filter\u003c\/li\u003e \u003cli\u003e21mm clear filter aperture\u003c\/li\u003e \u003cli\u003eTuned to 0.5-0.3? for viewing chromosphere details\u003c\/li\u003e \u003cli\u003eTuning knob allows for ±0.5? wing shift for Doppler-shift compensation\u003c\/li\u003e \u003cli\u003eMarkers at every 0.1? for reference and repeatability\u003c\/li\u003e \u003cli\u003eInternal baffles increase contrast\u003c\/li\u003e \u003cli\u003eOptical coatings designed specifically for 656nm H-alpha wavelength\u003c\/li\u003e \u003cli\u003eLED indicators for power, warming, ready, and fault\u003c\/li\u003e \u003c\/ul\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdt\u003eUse and Handling\u003c\/dt\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003eBuilt with Questar eyepiece and rear port threads\u003c\/li\u003e \u003cli\u003eFor off axis energy rejection filters\u003c\/li\u003e \u003cli\u003eBrass compression ring to protect eyepiece from scratches\u003c\/li\u003e \u003cli\u003eAccepts 1.25\" eyepieces\u003c\/li\u003e \u003c\/ul\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdt\u003eRecommended OTA Specifications\u003c\/dt\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003eFor use with Questar telescopes\u003c\/li\u003e \u003cli\u003eNo aperture limitation\u003c\/li\u003e \u003cli\u003eMust use a front-mount energy rejection filter to prevent overheating the OTA\u003c\/li\u003e \u003cli\u003eNot for use with full aperture Schmidt-Cassegrain ERFs - damage to secondary mirror may result\u003c\/li\u003e \u003cli\u003eBest performance with f\/13 and slower focal ratio OTAs\u003c\/li\u003e \u003c\/ul\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdt\u003ePower\u003c\/dt\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003e5 VDC, 1.5A micro-USB port\u003c\/li\u003e \u003cli\u003e90-240 VAC wall adapter\u003c\/li\u003e \u003cli\u003eSet of international outlet plugs for US, UK, EU, and Australia\u003c\/li\u003e \u003c\/ul\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cspan\u003eUPC: 702730991039\u003c\/span\u003e \u003c\/div\u003e \u003c\/div\u003e\u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003eType\u003c\/td\u003e \u003ctd\u003eHydrogen-Alpha\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eFilter Factor\u003c\/td\u003e \u003ctd\u003e0.5 - 0.3 ?\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eBlocking\u003c\/td\u003e \u003ctd\u003e25 mm, 21 mm clear aperture\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eApplication\u003c\/td\u003e \u003ctd\u003eChromosphere viewing\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eSize\u003c\/td\u003e \u003ctd\u003e Questar eyepiece and rear port thread \u003cbr\u003e Accepts 1.25\" eyepieces \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMulti-Coated\u003c\/td\u003e \u003ctd\u003eYes\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePower Requirement\u003c\/td\u003e \u003ctd\u003e5 VDC, 1.5 A\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eConstruction\u003c\/td\u003e \u003ctd\u003eAluminum alloy\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eDimensions\u003c\/td\u003e \u003ctd\u003e5.7 x 2.8 x 2.2\" \/ 14.6 x 7.1 x 5.5 cm\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e\u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003eIn the Box\u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003eDayStar Filters Questar Quark H-Alpha Eyepiece Solar Filter (Chromosphere)\u003c\/div\u003e \u003c\/div\u003e \u003cul\u003e \u003cli\u003eWedge Adapter\u003c\/li\u003e \u003cli\u003eQuark H-Alpha Filter\u003c\/li\u003e \u003cli\u003ePlastic Case\u003c\/li\u003e \u003cli\u003eUSB Power Cord\u003c\/li\u003e \u003cli\u003eWall Outlet Power Adapter\u003c\/li\u003e \u003cli\u003eSet of International Plug Adapters\u003c\/li\u003e \u003cli\u003eLimited 10-Year Warranty\u003c\/li\u003e \u003c\/ul\u003e \u003c\/div\u003e \u003c\/div\u003e All product and company names are trademarks™ or registered® trademarks of their respective holders.
