Where to buy a legal green laser for astronomy use

[superiorstream]

Hi,Everyboby,
It must be added that LASER are very dangerous light because its coherent and energy is concentrated at a very very small area.If you do read the early literature of laser research, there are many incidents(not publicise) whereby even researchers get slow and eventual blindness due to exposure to laser light.Some laser light,esp in the high frequency range can cause cell mutation.Thus i dont see why you go thr the trouble to obtain the laser to guide your telescope?---when a simple red dot finder or a good 50mm viewfinder can fulfil the same purpose.Thanks

Hi superiorstream,

The thread starter may not be using the laser to guide his scope, but instead use it during a group observation session to easily point out stars and constellations to others with the visible laser beam. I got my 5mW green laser last year before I got my binoculars for the exact same reason. Also, green laser rated at a 5mW output power is safe to use, as long as one do not intentionally shine it into other's optical path since the beam is not as strong as lasers with the capability to burn/light matches or cigarettes.

Either way, do use lasers with caution.

Regards,
Zane

Hi,

That guy whom I brought from have a range of 30 50 75 100 120 150 200mw etc etc, he also add on that 300Mw are banned in Singapore. Hence, I'm not sure who's right here, Mr. Zephyrus? Or him (:

On the other hand, if you are paying 140 bucks for such a low Mw Laser, why not pay more for a higher one, right? Quid pro quo (: and moreover, if you do get it, w/o a license like me (with reference to Mr. Zephyrus post) the police ain't gonna come over your house or wherever you are and seize you. Perhaps someone really likes to follow the laws, i don't know (:





these photo are taken straight away after i saw you post regarding the 139 Bucks laser with 400 ISO through my LG Viewty phone. and I didn't have new pairs of batteries, if i do, the beam would be brighter.

P.S. >5Mw limitation is just lame, and OH, don't point a 100mw laser directly to your eyes, You do not want to lose your eyesight and end your Astronomy hobby, do you? (:

We can't force people to follow the law, but please be reminded that you had been informed and warned about it.

By the way, please use your green laser pointer with care and responsibly:
1) Don't point at any reflective surface, building, animals and of course people.
2) Don't point near or at any aircraft!!!

We don't want to end up like Australia which I think already ban all laser pointer above 1mW.

Have a nice day.

OH, sorry, I didn't realize we're actually debating (: you must have put in a lot of effort researching in that 42 minutes.

Awesome work, we have a winner here, ya da ya da. kiwitan you shall get a legal laser, i'm sure you don't want someone reports you to the police or make a complain about using the laser in an inappropriate way or Any one found using class 3b & 4 lasers without licence in Singapore would be charged for violating the Act and could be fined up to maximum of not than $10,000 or imprisonment for a term of not exceeding 12 months or both.

You do not want to lose your eyesight and end your Astronomy hobby, do you? (:
