It's the same for New Zealand, as far as I know. I had to become a member of the RASNZ (I'm an astronomer, so I was going to anyway) and the President sent me a letter that I can whip out on my phone if the police swing by my observing site.

<p>This is poor dark sky etiquette.  Even when you're &quot;by yourself&quot;, the laser is visible from a long way away (miles away sometimes).  And you can't possibly know who's doing what in the entire visible area.  What makes it even worse is you'll be using it to point at popular targets other people will be using telescopes to look at, increasing the visible range even further.</p>
<p>They are also generally unnecessary, because if you know where an object is well enough to point a laser at it, you can point a telescope at it.</p>

I do concur with what you say, yet I'm not sure this answers the question - but then, and as already commented above, I'm not convinced of what *is* the actual question here... why would I use a laser pointer to guide *myself*?!

<p>Can I use a laser spotter as a guidance to a star in the sky?
That's if you're by yourself. Here is an example of a spotter on a tripod 10 feet any from my camera!</p>

I don't get the question. To me it looks like "can I do what I show you here in the photo and what I do regularly"

@planetmaker: That is indeed the question. However, the question is not merely “can I do it?” as in “is it possible?” but more like “can I *legally* do it?”

I don't unerstand why the visible trace stops at the star or planet.

@stretch it doesn't. It only appears to do so. Visibility is limited by all of: the density of the atmosphere, the atmosphere's aerosol content which scatters the light better than air, the width of the laser beam, and the distance of the point towards your eye, and of course the laser intensity itself.
