Explore Scientific ReflexSight

A 3-Circle Reticle (4°, 2°, and 0.5°) for Pinpoint Star Hopping

The ReflexSight uses a time-tested reticle pattern that projects three concentric circles measuring 4.0, 2.0, and 0.5 degrees. This pattern allows you to accurately frame celestial objects and gauge angular distances for star hopping. The reticle itself is a "multi-dot" design, meaning the circles are composed of individual points of light, preventing the reticle from completely obscuring stars that fall directly on the circles.

A large, knurled knob provides continuous brightness adjustment with a wide dimming range. This is a critical improvement, allowing you to lower the illumination enough to see faint stars through the reticle, a common challenge with lesser red dot finders.

Mini-Vixen and 1/4x20 Mounting for Broad Compatibility

Designed for maximum versatility, the ReflexSight attaches directly to any telescope equipped with a common mini-Vixen-style dovetail viewfinder base. For additional uses, a 1/4x20 threaded adapter is built directly into the base, allowing you to mount the finder on a photo tripod or a piggyback camera adapter for wide-field aiming.

It is important to note this finder's primary limitation: it is not compatible with the older Explore Scientific/Meade-style inverted T-slot finder bases. For telescopes with non-standard bases, the Explore Scientific Hybrid Finder Scope Base can be used to adapt the ReflexSight.

Field-Ready Design: 2-AAA Power and Glove-Friendly Controls

The ReflexSight is engineered for practical use in the field. It operates on two lightweight and commonly available AAA batteries, and its low power draw ensures long operating times. The battery compartment is easily accessible for quick changes in the dark.

Both the brightness control and the three rear-facing parallax adjustment knobs are oversized, knurled, and smooth, allowing for easy operation even while wearing gloves on a cold night. A definitive click indicates the full-off position, preventing accidental battery drain during storage.

ReflexSight vs. Telrad: Compact Form vs. Classic Design

The ReflexSight directly competes with the classic Telrad finder, even adopting its standard 4°, 2°, and 0.5° reticle pattern. The choice between them comes down to form factor, mounting, and power.

• Mounting: The Telrad requires its own dedicated base plate to be attached to a telescope, while the ReflexSight mounts directly to the more common mini-Vixen finder shoe found on many modern telescopes.
• Size & Profile: The ReflexSight has a smaller, more compact body, which can be advantageous on smaller telescopes where space and weight are concerns.
• Power: The ReflexSight uses two AAA batteries. The Telrad uses two larger AA batteries. While both are common, the choice may align better with other accessories you own.
