Smaller, lighter and sharper, the Opticron HR 66 ED fieldscopes offer a host of improvements over preceding models and have been redesigned without compromise in order 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.
Delivering the highest resolution figures in the Opticron range, each model contains a high definition 5 element apochromat objective lens with 2 individual ED elements. In addition to enhancing resolution, this second element delivers significant reductions in chromatic aberration compared to single element designs.
To optimise light transmission and colour contrast across the magnification range, Opticron N-type extra wide band multi-coating is applied to all air/glass surfaces throughout each instrument.
Mechanically, Opticron HR ED fieldscopes feature a magnesium alloy body fitted with a +/- 90° rotating tripod sleeve. Fully nitrogen gas filled waterproof and hermetically sealed against penetration from dust and moisture, the models are protected in durable textured rubber armour. Other features include a centrally positioned focus wheel for optimum accessibility, retractable lens hood (sunshade) and integrated rubber objective lens cover. Opticron HR ED fieldscopes are supplied with a comprehensive 30 year guarantee.
Key features include:
Nitrogen gas filled waterproof construction for 100% waterproofing
Superior light transmission derived from the 66mm objective lens
High quality fully multi-coated optical system with ED (extra low dispersion glass) element objective lens

The Opticron SDL v2 Zoom Eyepiece offers variable magnifications (depending which scope it is mounted on) and a comfortable eye-relief of 20-18mm. SDL eyepieces maximise the performance gains inherent in Opticron ED objective lens fieldscopes at higher powers while maintaining superior cross-field definition at all magnifications coupled with exceptional viewing comfort. With an unrivalled combination of resolution and field of view, the 40936 delivers the highest resolution of any Opticron zoom eyepiece. At 77mm long and weighing 270g it is a convenient addition to any Opticron scope owner's kit.
Please note: 40936 eyepiece does not connect to HR60 pre-1998, Piccolo 60, Classic MKII, IF-2 MT/MTN telescopes
