This design enables the use of nighttime telescopes for solar viewing. In addition to the tunable H-alpha filter, the Quark also functions as a 4.3x Barlow lens, with a 2-element lens system designed to be telecentric which flattens the field of view and reduces parallax, and optical coatings that are optimized for the 656nm H-alpha wavelength.\u003c\/p\u003e \u003cp\u003eWhile there are no OTA aperture limitations, Daystar recommends the use of UV\/IR cut filters or front-mount energy rejection filters on OTAs over 80mm of for long-duration solar viewing sessions. For best results, they suggest using refractor-style scopes with focal ratios between f\/4-f\/8, and you can enjoy full-disk viewing with focal lengths up to 450mm. 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 12mm 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\u003eLED indicators for power, warming, ready, and fault\u003c\/li\u003e \u003c\/ul\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdt\u003eOptics\u003c\/dt\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003eIntegrated 4.3x Barlow lens\u003c\/li\u003e \u003cli\u003eLens and optical coatings designed specifically for 656nm H-alpha wavelength\u003c\/li\u003e \u003cli\u003eTwo-element telecentric lens design keeps light waves parallel to flatten the field of view and reduce parallax as magnification increases\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\u003eNo aperture limitation\u003c\/li\u003e \u003cli\u003eBest performance with f\/4-f\/8 refractors\u003c\/li\u003e \u003cli\u003eFull-disk viewing on refractors up to 450mm focal length\u003c\/li\u003e \u003cli\u003eFor apertures over 80mm (3.1\"), or for long-duration solar viewing, an UV\/IR cut filter should be used for energy rejection\u003c\/li\u003e \u003cli\u003eNot suited for off-axis applications\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: 702730990728\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\u003eApplication\u003c\/td\u003e \u003ctd\u003eChromosphere viewing\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eSize\u003c\/td\u003e \u003ctd\u003e Drawtube side: 1.25\"\/2\" \u003cbr\u003e Eyepiece holder: 1.25\" \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 \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003cth\u003e \u003ca\u003ePackaging Info\u003c\/a\u003e \u003c\/th\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePackage Weight\u003c\/td\u003e \u003ctd\u003e2.25 lb\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eBox Dimensions (LxWxH)\u003c\/td\u003e \u003ctd\u003e10.8 x 4.3 x 4.1\"\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 QUARK H-Alpha Eyepiece Solar Filter (Chromosphere)\u003c\/div\u003e \u003c\/div\u003e \u003cul\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.

To fit your camera system, the each end is equipped with a corresponding bayonet mount for easy attachment, and full disk viewing possible on lenses up to ~450mm focal length. A rear 1.25\" eyepiece adapter is included to allow the use of traditional astronomical eyepieces. This adapter essentially converts your lens into a solar telescope. Daystar recommends the use of red, orange or yellow colored glass lens front filters for apertures over 80mm. \u003c\/p\u003e \u003cp\u003eThe filter is tuned to the 0.5-0.3? bandwidth of the 656nm hydrogen-alpha wavelength with the ability to tune it ±0.5? from the center line for compensate for Doppler shift or to focus on specific regions or features, with indicators every 0.1?. 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 experience. 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 \u003cp\u003eThe Camera Quark comes with a combination lens foot with 1\/4-20 tripod holes to mount it on conventional photo\/video\/field tripods, and a Vixen-style dovetail plate for telescope mounts. While a focal extender spacer ring is included to ensure compatibility with a wide variety of lenses, focus and clearances are not guaranteed with all Nikon lenses.

To fit your camera system, the each end is equipped with a corresponding bayonet mount for easy attachment, and full disk viewing possible on lenses up to ~450mm focal length. A rear 1.25\" eyepiece adapter is included to allow the use of traditional astronomical eyepieces. This adapter essentially converts your lens into a solar telescope. Daystar recommends the use of red, orange or yellow colored glass lens front filters for apertures over 80mm. \u003c\/p\u003e \u003cp\u003eThe filter is tuned to the 0.8-0.6? bandwidth of the 656nm hydrogen-alpha wavelength with the ability to tune it ±0.5? from the center line for compensate for Doppler shift or to focus on specific regions or features, with indicators every 0.1?. Prominences, a detail of the chromosphere projected against the blackness of space behind the sun, are seen with improved contrast due to the filter's narrower bandpass versus a wider bandpass filter tuned for conventional chromosphere surface viewing. 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 \u003cp\u003eThe Camera Quark comes with a combination lens foot with 1\/4-20 tripod holes to mount it on conventional photo\/video\/field tripods, and a Vixen-style dovetail plate for telescope mounts. While a focal extender spacer ring is included to ensure compatibility with a wide variety of lenses, focus and clearances are not guaranteed with all Nikon lenses. Because there is no electric pass-through on the filter, when installed between the camera body and lens, some lens features such as auto-focus and electronic aperture control will not work.\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 12mm blocking filter\u003c\/li\u003e \u003cli\u003e21mm clear filter aperture\u003c\/li\u003e \u003cli\u003eTuned to 0.8-0.6?
