The Skywatcher Esprit 80ED 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 2.7" linear power focuser is solid, precise and backlash free. 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 80ED includes a two element field flattener, correcting the frame for field curvature and providing a 33mm imaging circle, making it suitable for APS-C sensors and smaller.

 

 

The Esprit 80ED Pro includes a high quality 2" dielectric diagonal, right angled 9 x 50 finderscope, 1.0x field flattener, Canon EOS M48 T-ring, plus adapters for connecting common accessories and a heavy-duty hardcase.
