HR ED FIELDSCOPES
HR 66 GA ED, HR 80 GA ED
Smaller, lighter and sharper the new HR ED fieldscopes offer a host of improvements over preceding models and have been re-designed without compromise to deliver truly exceptional optical performance combined with sublime handling and complete reliability.
Aimed squarely at the serious fieldscope user, the models are built to withstand extremes in temperature, to operate unaffected by rain, cold or humidity and as such can be used anywhere from equatorial rainforests to the poles. The choice of body types, viewing eyepieces and dedicated accessories for observation and photography are unparalleled and combine to create the most versatile and complete range of fieldscopes we have ever produced.
The reconfigured optical systems deliver the highest resolution of any Opticron telescope and are matched directly to the SDL zoom eyepiece for constant focus across the magnification range 18-54x (66)/24-72x (80). Both the 66mm and 80mm feature a high definition 5 element apochromat objective lens system with 2 separate ED elements, and Opticron N-type multi-coating. The combination maximises resolution and colour contrast especially at higher magnifications across a wide range of different light conditions.
Mechanically the HR ED feature a new lightweight magnesium body complete with large footprint tripod adapter with +/- 90 degree rotation. Fully nitrogen gas filled waterproof and hermetically sealed against penetration from dust and moisture, the models are protected with a textured and highly durable natural rubber armouring. Other features include a centrally positioned rubber armoured focusing wheel for optimum accessibility plus a new retractable rubber covered lens hood with integrated rubber objective lens cap. HR ED fieldscopes are supplied with a comprehensive 30 year guarantee.
The advantages of ‘ED’
By using ED or ‘extra low dispersion’ glass elements in the primary objective system, these fieldscopes provide a higher degree of colour correction compared to conventional glass objectives.
More apparent at higher magnifications and under certain light conditions (e.g. when looking over water on a bright warm day) the image appears sharper and colours remain truer to life across the magnification range. The ability to bring into clear and sharp focus indistinct objects such as coloured identification rings or shades of plumage in poor light over long distances are the hallmarks of an HR ED fieldscope. This extra optical clarity combined with all the features and exceptional build quality make them the definitive choice for the professional ornithologist.
In addition to improved viewing capability at higher magnifications, the benefits of using an HR ED fieldscope for telephotography with either compact digital or SLR cameras cannot be overstated. The 41110 Telephoto HDF conversion for SLR (1000mm - HR66 / 1350mm - HR80) is designed to meet the demands of the amateur wildlife photographer and when used in conjunction with an HR ED fieldscope ensures the very best definition and colour reproduction.
HR 66 GA ED
Weighing just over 1200g and 290mm in length, the 08 model HR 66 really lives up to its reputation delivering arguably the highest resolution of any comparable compact prismatic fieldscope on the market today.
It’s not just the resolution that makes this ‘scope really special. When fitted with the HDF T 20xWW, 28xWW, 38xWW ‘flat field’ or the SDL 18-54x eyepieces, viewing comfort is unparalleled - an essential quality when viewing for long periods or in poor light.
HR 80 GA ED
With a 570mm focal length objective and outstanding low light performance, the HR 80 GA ED 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 plus the stunning SDL 24-72x for superb long range viewing.

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.
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.
