Sky-Watcher Esprit 150ED Triplet Super APO - High-end f/7 apochromatic refractor

The Sky-Watcher Esprit 150ED is the flagship of the Esprit range, designed for the most demanding astrophotographers and observers. With its 150 mm super-apochromatic triplet lens with air-spaced lenses (BK7 and FPL-53), it virtually eliminates colored fringing and delivers exceptional contrast, even on the brightest stars. Each element is treated with the high-transmission metal coatings (MHTC™) for optimum light transmission.

Sa 1050 mm focal length (f/7) and its doublet field corrector included guarantee a perfectly flat field across the entire sensor, from full-frame to large modern CMOS. The focuser 3.4″ double-speed rackThis Helinear rail-mounted system enables smooth, precise, backlash-free focusing, and can be rotated for easy framing of your images.
