Explore Scientific ReflexSight

A zero-magnification reflex finder with a multi-ring reticle (4.0°, 2.0°, and 0.5° circles) and an ultra-dimmable red LED — designed for star-hopping under dark skies without washing out faint targets.

The concentric circles let you estimate distances and frame objects before looking through the eyepiece. The red reticle dims low enough for dark-adapted eyes. Mounts via a mini-Vixen-style dovetail on common finder bases (not the Explore Scientific/Meade-style upside-down T base on older First Light, Essential Series, FCD100 and FLP53 telescopes), or directly on a tripod/camera mount with the built-in ¼-20 thread. Tool-free three-point alignment with glove-friendly knurled knobs. Powered by 2x AAA batteries.
