HOTECH Astro Presenter Green Laser Pointer with Continuous ON Position

The Astro Presenter is the first of its kind to have two laser activation features.  The 5mW laser can be activated momentary during presentation by using the round toggle switch for a quick pointing.  And the laser can be activated continuously with the sliding switch.  Ideal to use as a star finder for a telescope or any aiming puspose.  The continuous ON switch frees user's both hands to slew the telescope with the aid of the activated laser beam to the desire star without holding the laser activation switch like others.
 

In addition, the Astro Presenter uses the included high capacity CR123, 3V lithium battery which provides over 6 hours of continuous use battery life time.  The battery operates well under a typical cold night and it has a 10 years shelf life.  This is a great advantage not having to worry about changing batteries frequently in the dark like other pointers.

Constant ON/OFF Laser Activation Switch
When using your Astro Presenter as a finderscope on your telescope, the constant ON laser switch frees both your hands to aim your telescope without holding the push button switch like the conventional laser pointers.
 
High Output Green Laser
5mW, Class IIIa high power green laser at 532nm wavelength.  Green laser is 20 times brighter than red laser at the same output power as perceived by human eyes. The effective visual range allows audiences within 3 meter radius around you to clearly trace the laser line to the pointing star.

Automatic Laser Power Feedback Control
The laser has built-in power feedback circuit that constantly monitors laser power to keep the laser output stable.  The feedback control allows the laser to operate in a wider temperature range.
