  • Rigel System PulsGuide Jr Pulsing Finder Illuminator

    The Rigel System PulsGuide Jr Pulsing Finder Illuminator pulses its 660 nm red LED reticle illumination to let your eye rest between pulses, improving contrast between the reticle and faint objects. This illuminator features a fixed 2:1 on/off pulse ratio that is adjustable from a slow blink to a continuous-on state. Its compact 57 mm body is threaded for the modern M8 x 1.0 mm standard found on many finderscopes and finder eyepieces.

    The Pulsing Advantage: A 660 nm LED for Faint Object Acquisition

    Staring at a continuously illuminated reticle fatigues your eye and reduces your ability to see faint targets. The PulsGuide Jr solves this by pulsing the 660 nm red LED, which improves the contrast between the reticle and faint objects. This brief "off" period lets your eye rest, for easier acquisition of faint objects in your finder.

    Intuitive Control: Adjusting Brightness and Pulse Rate from 2:1 to Continuous

    The PulsGuide Jr uses a simple two-knob control system. The black knob at the end of the unit serves as the on/off switch and brightness control, allowing you to dial in the perfect reticle intensity for your target. The white knob adjusts the blink rate of the fixed 2:1 on/off ratio pulse, from a slow, methodical blink to a rapid pulse, or turned fully clockwise for continuous, non-pulsing illumination.

    Compact 57 mm Design and M8 x 1.0 mm Threading

    With its black anodized aluminum body, the PulsGuide Jr is just 57 mm (2-1/4 in) long. It is designed to fit finders and finder eyepieces that use the common M8 x 1.0 mm thread size. For an older finder with an M8 x 0.75 mm thread, Rigel Systems asks owners to contact them.

    PulsGuide Jr vs. Standard PulsGuide: Key Differences

    Rigel Systems produces two versions of their pulsing illuminator. The PulsGuide Jr is the more compact and simplified model, ideal for finderscopes.

    • Pulse Control: The standard PulsGuide offers two knobs to independently control the on-time and off-time of the pulse. The PulsGuide Jr simplifies this with a single knob that adjusts the speed of a fixed 2:1 on/off ratio.
    • LED Color: The PulsGuide Jr uses a fixed 660 nm red LED. The standard PulsGuide includes both red and yellow LEDs, allowing the user to switch between them.
    • Size: At 57 mm (2-1/4 in) long, the PulsGuide Jr is 1/2 in shorter than the regular PulsGuide.

  • How does the PulsGuide Jr's pulsing action help find faint objects?

    By briefly turning the reticle illumination off in a 2:1 cycle, the Rigel System PulsGuide Jr allows your eye to rest and rest between pulses. This improves the contrast between the reticle and faint targets like galaxies or nebulae, which can be washed out by a continuously-on illuminator.

    Will the Rigel System PulsGuide Jr fit my 8x50 finderscope?

    It depends on the thread size of your finder's illuminator port. The PulsGuide Jr uses a standard M8 x 1.0 mm thread. It fits current finders and finder eyepieces that use this thread; check your finder's thread before ordering. It will not fit older finders with an M8 x 0.75 mm thread.

    How do I control the brightness and pulse rate on the PulsGuide Jr?

    The PulsGuide Jr has two simple controls. The black knob on the end turns the unit on and adjusts the brightness of the LED. The white knob on the side controls the blink rate, allowing you to adjust it from a slow pulse to a fast one, or turn it to the end of its travel for continuous, non-pulsing illumination.

    Can I set the PulsGuide Jr to be continuously on without pulsing?

    Yes. While its primary feature is pulsing, you can achieve a continuous "on" state. Simply rotate the white blink-rate knob fully clockwise, and the illuminator will stay on without pulsing.

    What battery does the PulsGuide Jr use, and is it included?

    The PulsGuide Jr uses one CR1/3N (or DL1/3N) lithium battery. One battery is included.

    My finder has an M8x0.75mm thread. Can I use the PulsGuide Jr?

    The PulsGuide Jr is built with an M8 x 1.0 mm thread. For an older finder with an M8 x 0.75 mm thread, Rigel Systems asks owners to contact them and says it can accommodate.
