Guiding Eyepiece Illuminator


 PulsGuide + 12.5mm
Plossl Eyepiece


Already have a PulsGuide?
Plossl Eyepiece


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 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 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.

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...".
Phillip S. Harrington in Star Ware


PulsGuide Jr
Pulsing Finder Illuminator

 Pulsguide Jr


Less Eye Fatigue = Better Acquisition -- PulsGuide pulses the finder crosshair illumination to let the eye rest between pulses. The result? Improved contrast between reticle and faint objects for easier acquisition of faint objects in your finderscope.

Night Vision Safe 660nm Red LED and long life CR1/3N battery included Black anodized aluminum body and large easy grip plastic on/off/brightness knob.

One Knob Timing Control and Adjustable Brightness --Fixed pulse ratio of 2/1 adjustable from fast to slow blink.

Fits all Current Finders and finder eyepieces using M8x1.0 thread. If you have an old old older finder with the M8x0.75 thread, contact us and we can accommodate.  

Compact 2 1/4 inches long, 1/2 inch shorter than regular PulsGuide.
