Of course some may be wondering what the heck do you do with a 250mw class laser. I've found the following uses.

1) Align telescope scope optics in daylight
2) Check sky transparency (the Darth Vader look is in fact, bad)
3) Rough polar align
4) Point out objects to non-astronomers
5) use as a finder scope
6) create holograms

non astronomy uses include
7) Stop/scare away sulphur crested cocky's who chew bits of my house.
8) use as a toy to pop balloons, burn holes in plastic tape etc
9) use as an engraver for dark plastics
10) amuse my cats who like to chase the green dot.

As far as the dangers go...yes if you stare at the beam you will damage your retina just as you would if you stare at the sun. Fact of the matter is your body's natural response is to want to look away.

A brief flash does leave an after-image, but no worst that a good photographic flash-gun.
(oh my god...flash "gun" they'll probably be classed as weapons next!)

...how I loathe flaccid minded law makers....

Burn skin...well...not really....you have to hold the spot steady and then you can feel something like a sugar ant bite at best...yes I can see why they are on the prohibited weapons list in Vic.
