Detalhes do Produto
The Levenhuk Ra FT72 ED PhotoScope is an apochromatic refractor for astrophotography. This telescope can be used as a spotting scope as well as a camera objective lens. It can be used to observe space, but the main purpose of the telescope is photography. Due to the extra-low dispersion optics and eyepiece that efficiently collects light, this telescope renders a highly contrasting image with a minimum of chromatic distortion. The kit also includes an aluminum case that makes the transportation and storage of the telescope easier.The Levenhuk Ra FT72 ED’s main feature is a 2” helical focuser. It is robust and allows for very accurate focusing and smooth movement without backlash. It provides crisper and sharper images than a rack and pinion focuser or even the more advanced Crayford focuser can provide. It is also compatible with heavy accessories.The optical tube has a standard 1/4” thread, so that it is compatible with the most of modern mounts and tripods. To install a SLR camera, you need a special adapter, which is not included in the kit.Features:Apochromatic refractor with extra-low dispersion opticsFully multi-coated lenses render the brightest pictureMinimum chromatic distortion, wide field of view, and high contrastHelical focuser provides precise focusingSuitable for professional astrophotographyCompatible with 2’‘ accessoriesThe kit includes:PhotoScopeCleaning wipeAluminum caseFocuser protective capEyepiece protective capUser manual and lifetime warrantyBrandLevenhuk, Inc., USAWarranty, yearslifetimePackage size (LxWxH), cm56x23x20Shipping Weight, kg4.7Optical designrefractorOptical schemeapochromatOptics materialEDOptics coatingfully multi-coatedObjective lens diameter (aperture), mm72.0Focal length, mm432Highest practical power, x144.0Aperture ratiof/6Resolution threshold, arcseconds1.61Focuser2” helicalOptical tube mounting mode1/4” threadOptical tube materialanodized aluminumUser levelbeginnersObserved objectplanets of the Solar System
