Celestron NexStar 127SLT

Celestron's 127mm Maksutov on the NexStar SLT GoTo alt-azimuth mount. The combination of Mak-Cas optical quality — sharp, high-contrast, zero-maintenance — with GoTo pointing makes this a compelling mid-range scope. The SLT hand controller can find and track over 4,000 objects. The 127mm aperture delivers capable planetary views, with sharper contrast than a 130mm Newtonian of comparable price. For visual deep sky, a 200mm Dobsonian at the same price delivers more light — the NexStar 127SLT earns its premium through GoTo convenience and the Mak-Cas optical design.
