Sky-Watcher Evolux 62 ED OTA
Kompakt ED-refraktor med 400 mm brennvidde og fast blendertall på f/6,45. Kjøper man til focal reducer (se relaterte produkter nederst på denne siden) reduseres brennvidde og blendertall til hhv. 360 mm og f/5,8. Tuben er utstyrt med tannhjulstang-fokuser (rack & pinion) med todelt utveksling. Dette gjør det enkelt å foreta små justeringer på skarphetsplanet; en stor fordel i astrofotografisammenheng.
OBS: Fordi denne modellen er tiltenkt astrofoto leveres den helt "naken", dvs. uten speildiagonal/rettvendingsprisme, søkekikkert og okular. Tuben leveres imidlertid med 45 mm dovetail hurtigfesteplate samt en egen oppbevaringskoffert i aluminium.
Fra produsentens engelskspråklige presentasjon
Building on the foundation of the popular Evostar line of doublet ED refractors, Sky-Watcher has developed the all-new Evolux ED series. Designed for the discerning astrophotographer looking for a lightweight scope that still packs a punch. Naturally, Evolux ED models offer excellent performance for visual use too. Evolux ED models have key upgrades in the optics and the mechanics, making them the perfect fit for a widefield grab-and-go setup. Evolux ED apochromatic doublet refractors are the perfect blend of superior extra-low dispersion glass and affordability. The doublet lens assembly utilises a proprietary combination of optically matched lenses, including one ED lens element, that delivers sharp stars with charcoal-black, contrast-rich skies, whilst virtually eliminating false colour. All lens elements feature Sky-Watcher's proprietary Metallic High-Transmission Coatings™ (MHTC™) which are the finest photon anti-rejection coatings in their class, optimising light throughput to up to 99.5%! The Evolux-62ED can also be used as a deluxe guidescope. The Evolux-62ED comes in a foam-lined aluminum case with a 2.4-inch 11:1 dual-speed rack-and-pinion focuser, 45mm dovetail bar, clamshell ring, and adjustable dew shield. An optional 0.9x two-element focal reducer/field flattener, which includes one ED lens element and adaptor/field rotator is available separately, which when combined makes the Evolux-62ED into a four-lens optical system comprising two ED elements!
