Hello everybody!
I want to buy a green laser used only for star pointing (outside astronomy). This laser will not be used indoors or near anything reflective (used only in an open field/hill). I need the beam to be fairly visible, and not only on foggy days (as you cannot see many stars when you are surrounded by fog).
I've tried this with an overspeced 5mW (measured at around 10), but only a faint beam.
Could I have an estimate to how much power is needed?
A friend of mine bought these two lasers from DX:
$12.94 - 30mW 532nm Stars Light Show Special Effects Green Laser Pen (1*AAA) - Green Lasers
$18.60 - 100mW 532nm Green Laser Pen (2*AAA) - Green Lasers
He showed me that the laser beam is fairly bright, but I am asking for some advice from "the professionals".
Thanks for you time!
