I feel sorry for you, living under such miserable atmospheric conditions that a
<5mW red laser makes an effective pointer to celestial objects! But for anyone
living where the air is fairly clean, you really do need a green source if you
hope for people to see much. If it is very clean and dry (as where I live) even
the green laser is hard to see for anyone more than a few feet from the source.
