Explore Scientific Illuminator II Red LED Finderscope Illuminator

Redesigned to make it easier to power and use, the Explore Scientific Illuminator II Red LED Finderscope Illuminator now runs on two user-supplied AAA alkaline batteries that are not only easier to find than the small coin batteries previously used, but last longer. This updated model also features variable-intensity brightness control over the red illumination so you can carefully control how much the reticle is illuminated to make it easy to see without affecting your night-adjusted vision. Made as an upgrade for their straight VFEI0850-01 and right-angle VFEI0850-RA finderscopes, the Illuminator II will also work in most other illuminated finderscopes that use standard illuminators, and installs using the same mounting threads.
