DayStar Filters

Study the rich details of the sun's prominence using Daystar Filters Solar Scout 80mm f/17.5 H-alpha Achro Solar Telescope. Optically, this is an achromatic doublet refractor which corrects spherical and chromatic aberrations to produce accurate color rendition without distortion across the entire field of view. Included with the optical tube assembly is the Quark solar filter system, specifically tuned for prominence viewing. 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 Quark is an all-in-one hydrogen-alpha filter engineered to eliminate unnecessary components, which reduces the size and weight and enables it to fit in a compact form factor that simply inserts into drawtubes and accepts 1.25" eyepieces. In addition to the tunable H-alpha filter, the Quark also functions as a 4.3x Barlow lens with a two-element lens system that is 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. This design enables the use of nighttime telescopes for solar viewing, so it can be removed from the Scout OTA and inserted and used in many traditional telescopes.The Solar Scout is offered here as an OTA-only option, so a mount and tripod are required for proper use. Daystar includes a Vixen-style dovetail plate to be compatible with many mounts, and a 1/4"-20 mount on the plate allows it to be directly attached to many photo, video, or field tripods. Also included is a solar finder for safe alignment for observation, and a hard carrying case to protect it when it's not being used.Optical Tube 80mm aperturef/17.5 focal ratio1400mm focal lengthRefractor-style optical configurationAchromatic doublet lens design corrects spherical and chromatic aberration to produce accurate color fidelity without distortion across the entire field of viewSturdy and precise helical focuser has no backlash and won't rotate eyepiece/imaging rigCarbon fiber optical tube reduces weight without sacrificing strength, and resists the expansion/contraction caused by temperature fluctuations which can cause internal lenses to move out of alignment and affecting image quality and focusing abilityProminence Quark Hydrogen-alpha bandpassIntegrated 12mm blocking filter22mm clear filter apertureTuned to 0.5-0.3 for viewing prominence detailsTuning knob allows for 0.5 wing shift for Doppler-shift compensationMarkers at every 0.1 for reference and repeatabilityLED indicators for power, warming, ready, and faultIntegrated 4.3x Barlow lensTwo-element telecentric lens design keeps light waves parallel to flatten the field of view and reduce parallax as magnification increasesCombination 2" & 1.25" snout accepts 1.25" eyepieces and accessoriesCan be moved to other OTAsPower Requirements:5 VDC, 1.5A micro-USB port90-240 VAC wall adapterIncludes a set of international outlet plugs for US, UK, EU, and AustraliaMounting OTA only, mount and tripod requiredVixen-style dovetail plate is compatible with a wide variety of mounts1/4"-20 mounting socket allows the use of many photo/video/field tripodsWeight of 4.7 poundsAccessories Finder:Allows for safe alignment with the sunDoes not require directly looking at the sunSafely projects image of the sun on a small white screen for accurate alignmentCompact bullet designCarrying Case:Hard exterior protects for transport and storageFoam-lined interior
