Featuring an upgraded optical system for improved colour contrast and apparent resolution, ES v3 fieldscopes are designed and manufactured to deliver ‘best in class’ optical performance combined with rugged dependability and real user comfort.
The advantages of a 100mm diameter objective lens become clear when viewing at magnifications over 50x. With a surface area 1.5x that of an 80mm OG fieldscope, the ES 100 is easily able to out perform similarly specified 80mm (ED and Fluorite models) delivering brighter images with a higher resolving power. For terrestrial use, better definition and higher colour contrast mean more accurate and more enjoyable long range viewing. For Astronomy the ES 100's versatility as a compact F650mm 4' refractor with erected image viewing should also be considered. Magnification options for this application include HDF 6mm and 5mm long eyerelief eyepieces delivering 107x and 134x respectively.
Main features include a tri-element high definition objective lens with Opticron F-type multi-coating that visibly increases both colour contrast and clarity over standard multi-coatings, magnesium, aluminium and polycarbonate body protected in textured rubber armour plus nitrogen waterproofing to eliminate condensation.
Weight is kept to a minimum and the scope is well balanced for effective use on a tripod. Other features include a retractable lens hood, integrated rubber objective lens cover, conveniently positioned wide band focusing wheel and rotating tripod sleeve to enable maximum versatility in hides or viewing from a sitting or prone position.
ES models can be converted for use with SLR cameras for telephotography and are supplied complete with a 30 year guarantee.
