With outstanding low light performance, the HR 80 comfortably maintains superb colour contrast even in the poorest field conditions.
The long focal objective lens provides the unique opportunity of using long eyerelief, high power, wide angle HDF T 27xWW, 38xWW & 52xWW eyepieces for superb long range viewing, plus the option of HR2 27-80x and HDF T 24-72x zoom eyepieces.

HR 66 GA
Receiving the highest praise from independent surveys and industry alike, the HR 66 is firmly established as the preferred choice among fieldscope users everywhere. When used with the HDF T 20xWW, 28xWW and 38xWW 'flat field' eyepieces, image quality is both outstanding and very comfortable - essential when viewing for long periods.
Attention to detail in features such as natural rubber armouring, wide-knob focusing, rotating tripod sleeve & retractable lens hood, make the HR 66 the standard that other quality fieldscopes are judged against.

Eyepieces
A wide range of eyepieces are available for use with High Resolution 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.
