PulseGuide pulses the reticle illumination to let the eye rest between pulses. The result? Improved contrast between reticle and faint guide stars for easier guiding and better astrophotographs or acquisition of faint object in your finderscope.
Two Knob Timing Control and Adjustable Brightness. 2 knobs let you independently tailor on and off blink times from continuous on to long- on/short- off or short- on/long- off or anything in between.
Two Color LEDs -- Comes with red LED which you can switch to yellow LED by unplugging red and plugging in yellow. Some astrophotographers find low level yellow makes the cross hair clearer and sharper, and makes guiding even easier.
Use our quality, dual crosshair, 12.5mm Plossl eyepiece or with your eyepiece or finder. Fits standard 8mm threaded hole. 10mm and 14mm set-screw adapters available. Uses one long life lithium battery (included) that is available at most electronics, camera and hardware stores.
Customer Note: Photo is a little confusing...here's the scoop: It shows the complete reticle eyepiece with illuminator nearest the top, and then shows two illuminators, one with the red LED and one with the yellow LED. You don't actually GET three illuminators, however. The folks at Rigel just wanted to show you how the illuminator would look with either of the standard LED's installed. So, one eyepiece, one illuminator, and two LED's (red and yellow). is what you'll get if you buy this product. Whew, that was hard!
