Esprit series refractors are optical equipment designed for the most demanding astrophotographers and lovers of visual observations, looking for uncompromising solutions. All Sky-Watcher Esprit models are characterized by an almost complete reduction of optical defects in the field of view as well as off-axis aberration such as distortion or chromatic aberration.
The heart of the largest refractor from the Esprit family, the Sky-Watcher Esprit 150 mm F / 7, is an apochromatic triplet made of the highest quality Schott BK-7 and FPL-53 ED glass. Careful selection of materials for the lenses and their multi-layer anti-reflective coating guarantee a sharp image with perfect color reproduction. Additionally, a specially designed, internal system of partitions is responsible for obtaining a perfect contrast.
This instrument uses a dedicated flattener mounted with an M48 connector. It works with a CNC-made, solid extractor with a diameter of 3 ", capable of supporting a load of up to 5 kg without the risk of losing its alignment. In practice, this means that it can be used with even large professional SLR cameras can be connected to this refractor.
Due to the large diameter of the illumination circle of 43 mm, this refractor is the ideal device for use with cameras and SLR cameras equipped with a full-frame sensor. • APO ED triplet made of the highest quality FPL-53 ED and Schott BK-7 glass, covered with a multi-layer anti-reflective coating
