Rigel System eyepiece iluminator

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 objects 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).

It's perfect for the eyepiece supplied with our EZG-60 Guidescope and our finder models 60 mm. angle head, 50 mm. straight head, 50 mm. angle head, 80 mm. straight head y 80 mm. angle head, also works with brands' reticle eyepiece (8 mm. x 0.75 thread illuminator thread).

NOTE: Uses one 1/·N Duracell XL DL 1/3 lithium battery or equivalent.

Battery installation: Pull control knobs out of sides of body, grasp on/off knob and gently pull circuit board out. To reinstall, insert circuit board into tube and insert knobs through sides of body into holes on potenciometers. (click on the image to enlarge).



Please, be careful of battery polarity. Inserting battery with polarity reversed will damage circuitry and void warranty.


Here's Why PulsGuide Works:

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 because 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...".
