Rigel Pulseguide Illuminator

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.

NOTE: THIS STANDARD ILLUMNIATOR WILL FIT MOST GUIDING RETICLES INCLUDING MEADE, CELESTRON AND ORION!

Fits standard 8mm threaded hole. 10mm and 14mm set-screw adapters available.
