Careful and considerate use is essential when dealing with lasers. All amateur astronomers should be well-informed of basic "laser pointer etiquette".

Of course, never point it at any living being, not even animals (hey, I'm a naturalist as well!). Never point it towards buildings and vehicles (we can never know whose eyes may happened to be in the light path). Never point at planes or even man-made satellites (a serious crash-landing may result).

Even in star-parties, if there are people doing astrophotography, a single shot of laser light will ruin their night's worth of wait for that particular photographic moment... an enraged gang of astrophotographers is certainly no less damaging than stray lasers (ok, you have been warned!)

I take 2 pcs thanks

That's why I think using green lasers as finders is a bad idea.

i donno if this is just me, i can't use a laser because it made me nausea (once i almost vomit when someone next to me used a 20mW one).
Is this caused by radiation???

ps: being said that, laser is VERY helpful to help guide other scopes to quicly view the same object together.

That's why I think using green lasers as finders is a bad idea.

Actually I find using laser pointer more convenient, faster and more comfortable as you don't have to bend down to look through a finder.
Just don't use it in the company of others who are doing imaging, or next to someone who may vomit on your scope.

I find that green laser blinds me momentarily during obs sessions, even without looking at it directly... but then, if the sky is cloudy or raining, then green lasers are fun! Heh...

Oh, and as for green lasers ruining astrophotographs, the debate is still ongoing in another forum... basically, the effect is quite minimal if the laser is not stationary for more than one minute... but then, which astrophotographer is willing to risk it?

Thats why I am downgrading... I don't want to affect my night vision at Mersing.

Hi,

Wow! Your green laser so powerful... May be you got the "wrong" model?? Ha ha ha I use normal green laser, so I don't have the "blind" effect... ha ha ha

but then, which astrophotographer is willing to risk it?

That's why if I do imaging, I'll inform others of the "no laser zone"... ha ha ha

Have a nice day.

Actually anything that is higher power than the one I'm selling is illegal here. Checked with HSA.

Hi weichang, the laser pointer worked very well and highly recommended
i think it is brighter then most of the 5mw pointers used, and very blinding even as laser point on walls.

upz for good seller, and good product

remember to use with care...
