ES FIELDSCOPES
Updated and extended for 2004, the ES range sets a benchmark in affordable high definition Fieldscopes. Available in three variants: 80mm, 80mm ED and 100mm ED, the models are designed with one aim in mind; to provide 'best in class' optical performance and value.

The instruments really deliver in the most important area for the majority of users: image quality. The reduction of almost all visible chromatic aberration at 60x magnification on the base model ES 80 GA SD is a real breakthrough. It also sets the the standard on both definition and tonal quality that is successfully built upon with the more advanced ES 80 GA ED and ES 100 GA ED models.

Weight is kept to a minimum by the selective
use of tough plastics and aluminum components and the models are surprisingly well balanced for effective field use on a tripod.

All three are fully compatible with all HDF and HR eyepieces providing an exiting array of viewing options of 20x 100x (80mm models) and 30x to 134x (100mm).

Other features include full rain waterproof construction, a retractable lens hood, conveniently positioned wide band focusing wheel and rotating tripod sleeve to enable maximum versatility in Hides or viewing from a sitting or prone position.

For even greater magnification, the 2.5x UTA is available for HDF/HR eyepieces.
See: UTA. Models can be converted for use with SLR cameras for Telephotography
[see below] and are supplied complete with a 30 year guarantee

ES 100 GA ED/45

!
ES 100 GA ED/45 The advantages of a 100mm diameter objective lens cannot be overstated when viewing at magnifications over 50x. Having a surface are 1.5x that of an 80mm OG Fieldscope, the ES 100 GA ED/45 is easily able to outperform 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 HDF eyepieces include a 30xWW and 42xWW plus the 27-80x zoom.

For Astronomy, the ES 100's versatility as a compact F650mm 4 inch refractor with erected image viewing should not be underestimated. Magnification options for this application include 6mm and 5mm long eyerelief eyepieces delivering 107x and 134x respectively.

ES 80 GA ED/45 The ES 80 GA ED /45 has become one of the most popular birding scopes in the UK since its launch in 2001. The use of an ED objective or extra low dispersion glass element within the objective lens system virtually eliminates the distorting effects of chromatic aberration at magnifications over 35x. To benefit from this level of performance in a body retailing under £500 has caught the imagination of thousands of birdwatchers wanting vibrant 'true to life' images reproduced consistently across the magnification range. The model is most often seen with HDF eyepieces 20-60x and 32xWW. ES 80 GA SD/45

The suffix 'SD' for standard belies the quality of this Tri-element F500mm viewing platform. Fully multi-coated and complete with BK7 prism unit the ES 80 GA SD/45 demands serious consideration for anybody interested in a 80mm fieldscope. Image texture is softer than sister ED model but the instrument deals competently with a range of interspersed colours in varying light conditions combined with accurate focusing and a welcome lack of colour distortion.
