SKYWATCHER ESPRIT 150ED PRO APO TRIPLET

The Skywatcher Esprit 150ED PRO is an apochromatic triplet refractor that offers high performance for demanding astrophotographers. The objective lens features an element of extra-low dispersion glass (ED) that minimizes the chromatic aberration for the best colour correction. 

The 3" linear power focuser is solid and backlash-free, with zero image shift. It operates at two speeds due to the 11:1 reduction mechanism for extra fine focusing adjustment, which is paramount for astrophotography and high resolution observations. The knobs have been redesigned to allow smooth and accurate usage, even with gloves. The integrated rotator makes framing targets quick and easy.

The objective lens is fully multi coated with Skywatcher's proprietary new "Metallic High-Transmission Coating" (MHC) for an effective anti-reflection result that approaches a transmission of 99.5%. The aluminium tube has knife-edge baffles and is blackened to ensure high contrast and absorbing stray light.

The Esprit 150ED includes a two element field flattener, correcting the frame for field curvature and providing a 40mm imaging circle, making it suitable for large sensors.
