ES v3 FIELDSCOPES
ES 80 GA SD/45, ES 80 GA ED/45, ES 100 GA ED/45

 

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.

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 2.5x 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 latest optical upgrades, superior RI F-type multi-coating system and ED objective lens that virtually eliminates the distorting effects of chromatic aberration over 35x magnification all combine to further enhance the performance of this our most popular 80mm model. 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.

EYEPIECES
A wide range of eyepieces are available for use with ES fieldscopes. Choosing the best eyepiece is often confusing but making the right choice will depend on price and application. It is important to remember that the eyepiece is an integral part of the whole set-up and opting for a lower quality lens will make a difference to the overall image quality derived from the fieldscope.

SDL EYEPIECE CLICK FOR IMAGE
An F24 - F8, 5-group 8-element 'super' zoom, the 40935 SDL has been designed to maximise the performance gains inherent in Opticron ED objective lens fieldscopes at higher magnifications. Offering an optimum ratio between field of view and resolution, the main viewing characteristics of the SDL eyepiece are superior cross-field definition at all magnifications coupled with exceptional viewing comfort. Mechanically the eyepiece is waterproof, uses the M41.5 collar thread attachment, features a 90° rotation between high and low magnification settings plus a rotating eyecup that can be positioned to match individual needs. Supplied in soft padded case.

HDF EYEPIECES CLICK FOR IMAGES
The preferred choice for quality and viewing comfort, HDF eyepieces have large dia. eyelenses and provide 'walk-in' field of vision. All eyepieces feature long eyerelief for full field of view with or without spectacles and fixed magnification models are wide angle. Eyepieces in table marked * have a twist-type eyecup.
