Quattro imaging Newtonian är en prisvärd astrograf med stor bländare, idealisk för användare som söker efter ett snabbt bildsystem som fungerar för både astrofotografering och visuell astronomi. Med ett snabbt f/4-brännvidd kan denna astrograf producera en exponering 6 gånger snabbare än det genomsnittliga 8-tums f/10 Schmidt Cassegrain-teleskopet. Även om de är designade som ett optiskt bildrör, producerar dessa Newtonianer också ljusa och detaljerade visningar för visuell astronomi.
Liksom alla Sky-Watcher-reflektorer har Quattro imaging Newtonian borosilikatspeglar belagda med Sky-Watchers patenterade Radiant ™ Aluminium Quartz (RAQ™), som ger 94 % reflektivitet. Röret är konstruerat med valsat stål, sedan belagt med Sky-Watchers signatur glansiga metall-flake Black Diamond finish. OTA använder en överdimensionerad sekundär spegel som ger bättre belysning för DSLR och CCD med fullformatssensorer, och en valfri komakorrigering är tillgänglig för dem som vill ta sin bildbehandling till nästa nivå.
Quattro Newtonian medföljer en 10:1 dubbelhastighets 2-tums Crayford-stilsfokuserare, 1,25 och 2-tums okularadaptrar, ett 9x50 sökarkikare, rörringar och en laxstjärtsplatta i V-stil.
