Generally, green laser pointers are considered to be the best for astronomy purposes.
Green lights are several times more powerful than traditional red laser pointers.
Green lasers produce a beam that's 532 nanometers..
Green Laser Pointers (GLPs) are effective teaching aids for introducing people to the night sky.
Also, amateur astronomers sometimes use GLPs as aiming devices on telescopes.
At night the light beam of a GLP aimed into the sky is visible because the air scatters some of the light back toward observers on the ground..
Large lasers, such as the OMEGA laser at Rochester's Laboratory for Laser Energetics, have allowed researchers “to explode mini supernovas in their labs, reproduce environments around newborn stars, and even probe the hearts of massive and potentially habitable exoplanets,” Frank writes..
Laser pointers of power greater than 1 mW are not legal in WA.
Looking at a 1 mW laser is like looking at the sun..
This is a high power true 5mw, 532nm waveleangth laser that most astronomers use to point out objects in the night sky because the beam is vright and fully visible at night..
Under the South Australian Summary Offences Act 1953, hand held laser pointers with an output greater than 1 milliwatt are prohibited weapons..
A: Laser pointers with a power output of more than one milliwatt are now prohibited weapons.
You must obtain a permit to possess or use a laser pointer that is in this category, unless you use the pointer for activities associated with astronomy and are a member of an approved astronomical association..
A: Laser pointers with a power output of more than one milliwatt are now prohibited weapons.
You must obtain a permit to possess or use a laser pointer that is in this category, unless you use the pointer for activities associated with astronomy and are a member of an approved astronomical association..
That's why in Queensland, unless you have a reasonable excuse for possessing it, laser pointers with an output of greater than 1 milliwatt are a restricted item.
It's also an offence to point one at passing aircraft, or other vehicles..

Laser Pointers are prohibited Weapons in the Australian Capital Territory.
Specifically, Laser Pointer is defined as meaning a "prohibited weapon that is a hand- held article, commonly known as a laser pointer, designed or adapted to emit a laser beam with an accessible emission level of greater than 1mW"..
A: Laser pointers with a power output of more than one milliwatt are now prohibited weapons.
You must obtain a permit to possess or use a laser pointer that is in this category, unless you use the pointer for activities associated with astronomy and are a member of an approved astronomical association..
Factors like cloud coverage, fog, and if you're at a high point of elevation should be considered, but as a basic rule, you can expect over 10 miles of visible distance on green 200mW+ lasers and 1,000mW+ blue lasers..
Commonwealth Restrictions
According to the Australian Radiation Protection and Nuclear Safety Agency, In Australia, all laser pointers that are available to the public must have a radiant power output of less than 1 milliwatt (mW).
Please see their Laser focus on illegal imports article for more information..
Pointing a laser at an aircraft is a federal crime..

The range of the laser with a capacity of 10mW is about 5 kilometers..

The first red laser pointers released in the early 1980s were large, unwieldy devices that sold for hundreds of dollars.
Today, they are much smaller and less expensive.
The most common wavelengths are ca. 638 and 650 nm..
In 1960, Theodore Maiman at Hughes Aircraft used a ruby as a lasing medium to create “the first laser.” However, Gordon Gould (first person to even use the word laser), patented “the first laser” in 1977..

A laser pointer or any other article that's a hand-held battery-operated device with a power output of over one milliwatt, designed or adapted to emit a laser beam, which can be used for purposes of aiming or targeting or pointing is classified as a “prohibited weapon” in NSW making it illegal to carry or use unless .
It is the view of the ASSA that the safe use of hand-held battery-operated laser pointers is possible in Astronomy by following the guidelines presented below:
A laser pointer must only be used in accordance with the laws of the state or territory in which it is used.
The use of laser pointers in Queensland and NSW is restricted under the Weapons Act and Firearms Registry respectively.
Their use for astronomical purposes is considered a ‘reasonable excuse’ and laser pointers up to 20 millwatts are allowed.
A great green laser pointer for stargazing is the Z-Bolt Green Dot Laser Pointer Designator.
It has a strong green beam with a range of 5 miles.
It is also water-resistant and shock-resistant.
Can you point lasers in the sky? Yes
You can point lasers in the sky.
An astronomy laser pointer is a useful tool to indicate a constellation and the location of astronomical objects in the sky.
These devices are simple yet extremely powerful – you can use one even as a lighter for campfires.
We share everything you need to know about laser pointers and which one is the best laser for star pointing.
