8x50mm Illuminated Erect Image Finder

This 8x50mm straight through illuminated erect image finder will greatly aid the finding of fainter objects, which are invisible in devices of lesser aperture. This model features coated optics with built-in illuminated crosshairs in a brushed alloy finish and displays an upright image for those doing terrestrial spotting. The illuminator has a controllable range of brightness, which can be adjusted to suit the requirements of the user. The objective can be focused to desired range, then locked using the retaining ring. Comes complete with mounting bracket, primarily designed for ED triplets and doublets, but can also be fixed to other types of telescope.
