The PulsGuide Guiding Eyepiece Illuminator Makes Astrophotography Easier! Makes Finderscope Acquisition Easier, with its Pulsed Reticle.
Less Eye Fatigue = Better Astrophotographs! PulsGuide 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.
The Illuminator (this version only) includes Rigel's NEW, dual crosshair, 12.5 mm Plossl eyepiece! This is a great new eyepiece. the Plossl design gives a bright clear 50 degree field, with generous eye-relief and is far superior to the 12mm Kellner. This true 4-element design is multicoated and made in Japan.
Can also be used with your own eyepiece or finder. Pulsguide fits standard 8mm threaded hole. (10mm and 14mm set-screw adapters available.) Uses one long life lithium battery (included) that is easily available at most electronics, camera and hardware stores.

Works well, but in Questar telescopes, it does not reach focus with the integrated finder.
