  PulsGuide
Pulsing Eyepiece Illuminator
 

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.

 

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 night vision safe 660nm   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. Long life CR1/3N battery included.

 

Available With or Without Eyepiece -- Use our quality, dual crosshair, 12.5mm plossl eyepiece or with your eyepiece or finder. Fits standard 8Mx075 mm 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.

PulsGuide Jr Instructions

And We Can't Say It Better
"Some observers therefore prefer a cross hair that flashes on and off while guiding. For this reason, Rigel Systems designed a guiding light source called "Pulsguide", a simple but effective invention that pulses the reticle illumination of a guiding eyepiece during an exposure. On and off times and the reticle brightness are all variable and the unit is compatible with many existing guiding eyepieces. For guiding on very faint guide stars, I find this gadget invaluable." Martin Mobberley in Astronomical Equipment for Amateurs.

 

"PulsGuide solves the problem of how to guide on faint stars while keeping the crosshairs bright. I use mine constantly. I prefer a yellow reticle illuminator bec ause I'm sure my eye is focusing it in the same plane as the star." Michael Covington, author of Astrophotography for the Amateur.ause I'm sure my eye is focusing it in the same plane as the star." Michael Covington, author of Astrophotography for the Amateur.

 

"...indeed with PulsGuide I was able to track stars that were virtually at the limit of what I could see in the eyepiece when no reticle illuminaton was present." Dennis di Cicco in Sky and Telescope

 

"...fainter stars may be spotted and followed with greater ease...".
