Sky-Watcher Esprit 80ED Pro apochromatic refractor telescope with EQ6-R

Sky-Watcher Esprit 80ED Pro apochromatic refractor telescope with EQ6-R.

Large refractor telescopes are a dream for many people who want to obtain impressive planetary observations as well as inspiring deep sky images. The absence of central obstruction, the resulting image sharpness and the significant field of view, attract more and more of the amateur astronomy community to this optical configuration, valid for both observing and astrophotography.

To satisfy the most demanding users this new product line includes a high quality ED triplet. With an Ohara FPL-53 center element and two Schott lenses, Sky-Watcher has turned to the high quality of the Esprit to deliver high optical performance in planetary and deep sky imaging.

Designed for the advanced amateur astronomer, with its unique three-lens air-spaced design, chromatism is completely under control, image delivery is spectacular thanks to exceptional contrast.

The field corrector with two 48 mm lenses offers a perfectly flat field with a diameter of 44 mm. Its oversized lenses offer a wider and clearer aperture and have no internal reflection.

With this equipment you can enjoy the giants Jupiter and Saturn as never before, rediscover the Moon, and with its large diameter, you can photograph the most beautiful nebulae with the stars well spotted even at the edges of the field. With the 80 diameter you won't miss anything in the deep sky.

The absence of chromatic aberration, the focal ratio of 5 and the field flattener will allow you to obtain amazing results with an APS-C format sensor.

The telescope mounts a Crayford dual-speed 01:10 linear power focuser. To exploit this focuser to the fullest Sky-Watcher has designed a new 3'' eyepiece of patented design. The focuser is of CNC construction and its 01:11 development is smooth and precise, indispensable for obtaining a sharp image at high magnifications in visual or astronomical photography. The eyepiece holder is rotatable, which will greatly facilitate framing to give your shots a unique touch.

The optical tube is machined from aluminum, with retractable spray shield to make it more compact, and the interior is specially designed to reduce stray light. As a high quality detail, the lenses have a very high light transmission rate thanks to several metal deposits.
