Detalhes do Produto
The Levenhuk Ra R66 ED Doublet Black OTA apochromatic refractor is a short-focus optical tube that allows for getting an idea of the objects from the Messier and NGC catalogues as well as observe the relief of the lunar surface in detail. You can carry out planetary observations as well as deep sky observations. However, the primary use of this Optical Tube Assembly (OTA) is astrophotography. The pictures taken by this telescope are high contrast and very clear detail.The lenses are made of extra-low dispersion glass that effectively suppresses chromatic aberrations, especially secondary and spherochromatism. The wide field of view makes it comfortable to study extended areas of the sky. The telescope features a dual-speed Crayford focuser that provides smooth and highly accurate focusing under all conditions.The optical tube is made of anodized aluminum and can be installed on most modern mounts. As the OTA is quite lightweight and compact, it is a great choice for countryside trips. The kit also includes a convenient aluminum case for transporting and storing the telescope. Please note: Mount, tripod, and optical accessories are not included.Features:Compact and lightweight apochromatic refractorFully multi-coated glass lenses made of ED glassDual-speed Crayford focuser for precise focus adjustmentsExcellent image clarity and contrast, minimal chromatismExcellent choice for astrophotography, good for visual observationsThe kit includes:Telescope optical tubeCleaning wipeAluminum caseProtective capsUser manual and lifetime warrantyBrandLevenhuk, Inc., USAWarranty, yearslifetimePackage size (LxWxH), cm40.5x29.5x21Shipping Weight, kg4.37Optical designrefractorOptical schemeapochromatOptics materialEDOptics coatingfully multi-coatedObjective lens diameter (aperture), mm66.0Focal length, mm400Highest practical power, x132.0Aperture ratiof/6Resolution threshold, arcseconds1.75Focuser1.25”, Crayford, dual-speedOptical tube mounting modequick-release 1/4” thumbscrewOptical tube materialanodized aluminumUser levelbeginnersAssembly and installation difficulty leveleasyObserved objectplanets of the Solar SystemPouch in setTrue
