Astronomer's Green Laser Pointer
A high output green laser 3~4.9mW Class IIIa high output green laser at 532nm wavelength, 20 times brighter than red laser at the same output power as perceived by human eyes. The effective visual range allows an audience within a 3 meter radius around you to clearly trace the laser line to the star.
The laser has built-in feedback circuit that constantly monitors laser output power to keep the laser output stable. The control allows the laser to operate more stably under cold or warm ambient temperatures.
Easy telescope aiming with constant On/Off toggle laser switch.
Constant On laser switch frees both your hands to aim your telescope without holding the laser activation button, unlike conventional green pointers with a momentary switch.
