ES Fieldscopes
ES 80 GA SD/45, ES 80 GA ED/45, ES 100 GA ED/45

2006 - January 2009 models.
Listings for eyepieces and accessories are updated to reflect current models.

Designed and manufactured to deliver best in class optical performance combined with rugged dependability and real user comfort, the ES 80 SD and high performance ED models set new standards in quality and value.

Available in three variants; 80mm SD, 80mm ED and 100mm ED the instruments excel in the most important area for the majority of users: image quality. The reduction of almost all visible chromatic aberration at 60x magnification with the 80 SD sets the standard for both definition and tonal quality further improved upon with the 80 ED and 100 ED.

Main features include a tri-element high definition objective lens (SD or ED) 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 'scopes are 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.

Fully compatible with SDL, HDF and HR eyepieces the models offer an exciting array of viewing options of 20x to 100x (80mm) and 30x to 134x (100). For even greater magnification a 2x Tele-adapter is available for SDL, HDF and HR eyepieces.

ES models can be converted for use with SLR cameras for telephotography and are supplied complete with a 30 year guarantee.

ES 80 GA SD/45
The suffix SD for standard belies the quality of this tri-element F500 viewing platform. Utilising Opticron F-type high refractive index multi-coating complete with BK 7 prisms the ES 80 GA SD/45 demands serious consideration for anybody interested in an 80mm fieldscope. Image texture is slightly softer than sister ED model but the instrument deals competently with a range of interspersed colours in varying light conditions up to 60x magnification, combined with accurate focusing and a welcome lack of colour distortion.

ES 80 GA ED/45
The ES 80 GA ED/45 advances the tradition of quality and value started with the MKI ED with a new multi-coating system integrated into an all-new magnesium polycarbonate and aluminium body. 100% nitrogen waterproof, the fully rubber armoured body houses a high-grade ED (extra low dispersion glass) element within the objective lens system that virtually eliminates the distorting effects of chromatic aberration at magnifications over 35x. As a result, images are vibrant and 'true to life' and what's more - reproduced consistently across the magnification range.

ES 100 GA ED/45
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. Preferred eyepieces include the HDF 42xWW, 27-80x and SDL 27-80x. 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.
