Well,
http://www.yourlasers.com/ are a lot cheaper. 50mW lasers for $50 or less. BUT: they do NOT ship to US or Australia.
For pointing to stars, a 1mW green or 5mW red suffices unless you point in an urban area.
50mW pointers leave a clear green trail and might attract police or others particularly in NSW or ACT where this stuff is prohibited.
In a dark environment for people close to the laser pointer you can still see the trail very faintly with 1mW green or 5mW red.
But also these rather dim ones can damage eyes or distract people so NEVER point at people or driving cars.

I have not looked into green laser pointers yet. Some of the BAS club members use them as finders and to point objects out to the public. After being asked many times where in the sky the scope is pointing, I have started to toy with the idea of buying a GLP as well. |
