With M8x0.75 male threads and designed to fit their 8x50 and 9x60 finders and 12.5mm Micro Guide eyepiece, the Alpine Astronomical Baader Log-Pot Illuminator is also compatible with a wide variety of gear, from other manufacturers, that requires illumination—as long as the thread size and pitch are the same. A simple turn activates the light and controls the rheostat to dial in the right amount of light. The Log-Pot emits red light to preserve night-adjusted vision while allowing you to see the finder or eyepiece reticle. The illuminator runs on two included SR41W batteries.
