Rigel Systems PulsGuide JR: Enhanced Finder Scope Illumination for Easy Object Acquisition.

Reduces Eye Fatigue for Better Viewing: The PulsGuide JR pulses the finder crosshair illumination, allowing your eye to rest and resulting in improved contrast between the reticle and faint objects. This makes it easier to acquire faint objects in your finderscope.
Night Vision Safe Illumination: Features a 660nm Red LED that is safe for night vision, accompanied by a long-life CR1/3N battery, both included.
Durable and User-Friendly Design: Boasts a black anodized aluminum body for durability, along with a large, easy-grip plastic knob for on/off control and brightness adjustments.
Simple Brightness and Blink Control: Offers a fixed pulse ratio of 2/1, with adjustable settings ranging from fast to slow blinking to suit various observing conditions.
Universal Finder Compatibility: Designed to fit all current finders and finder eyepieces using the M8x1.0 thread. Accommodations are available for older models with the M8x0.75 thread upon request.
Compact and Efficient: Measuring 2 1/4 inches in length, this compact device is 1/2 inch shorter than the regular PulsGuide, making it a convenient addition to your astrophotography gear.
