Opticron GS 815 GA ED Spotting Scope - Angled

Specification:

This model is the preferred choice for those wishing to maximise light tranmission at magnifications between 30x and 60x . The ED version gives greater sharpness and more contrast for those using the higher magnification eyepieces. Opticron GS Fieldscopes are protected by 'full body' natural rubber armour with a textured finish to the top half of the main body prism housing. The centrally positioned focusing wheel allows easy access for both right and left handed users and is also rubber covered - delivering a positive feel with or without gloves./

The focusing system is designed to allow adjustment from infinity to 50 metres in just a 270° turn. Housed within the same mechanism for convenience is a 9:1 ratio accurate focus adjustment.

The importance of having access to full range of different magnification eyepieces is also important. As with most Opticron fieldscopes, the GS series are fully compatible with existing Opticron HDF/HR eyepieces including the 40862G HDF zoom 16-48x (665) / 20-60x (815) and 40809 HDF 25xWW (665) / 32xWW (815).

Designed to enable rotation around the main axis of the instrument for use on a bipod or in a hide with a high window, GS fieldscopes feature a solid die-cast tripod sleeve with -/+ 90 degrees each-way action with 45° incremental 'stops.

To avoid problem of reflected light on the objective lens in bright sunlight all models are fitted with a retractable lens hood extending 28mm (665) and 40mm (815). Reliability

Extensively tested for continuous trouble free use in varying temperatures, the models are fully nitrogen gas filled and waterproof and come with the assurance of a 30 year guarantee.

Eyepieces

A wide range of eyepieces are available for use with GS 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

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

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.

HR EYEPIECES

Good choice as either supplementary eyepiece in combination with HDF or single eyepiece for the more value conscious requiring long eyerelief. HR 40933 zoom eyepiece is an excellent choice for 665 models giving 18-54x. Eyepieces in table marked * have a twist-type eyecup.
