However, based on their pros and cons, the Pinty and Jemine laser pointers take home the crown. The Pinty laser pointer is best specifically for stargazing while the Twod Green Laser Scope is an all-around top-notch laser pointer that you can bring anywhere and anytime.
Buying Guide for You
If you’re thinking about getting a laser pointer for astronomy, there are some factors that you consider. The laser pointer you use for stargazing should be slightly different than the ones you use for casual use like presenting, playing with your pets, etc.
Different countries have different regulations for laser pointers. The regulations are usually based on the laser classification which indicates how powerful a laser beam can be. For instance, in the European Union, Australia, and New Zealand, a laser pointer for casual and personal use should not exceed 1 mW (Class 2). On the other hand, in the United States, the limit is higher at 5 mW (Class 3). Some countries like Switzerland only permit laser pointers in the Class 1 category or with the power output of 0.39 mW.
To know more about legal regulations for laser pointers, check out our in-depth article about laser laws and what type of laser pointers are prohibited.
Laser Power Output Recommendation
As per regulation, a laser pointer with a maximum power output of 5 mW should be fine. Anything that is too powerful can actually damage your sight in the long run. Your eyes need to constantly adjust to the bright light constantly which can be harmful to the optic nerve. Find a green or blue laser pointer with a power output of 5 mW if you’re in the United States or 1 mW if you’re in the United Kingdom. Any laser pointer exceeding 5 mW is not only illegal but also too dangerous to be used casually. Read more.
What model and how much should I spend?
There are a lot of great models of laser pointers that you can use for astronomy. There are laser pens, flashlight-styled lasers, scopes, and many more that you can choose from. The scope model is great if you’re planning to mount your laser pointer to other objects (like a telescope). Laser pens are highly useful for people who are always on-the-go and would like something more compact.
The cost of your laser pointer should also be a determining factor when you’re buying one. Just like many other things in the market, going cheaper doesn’t always mean you’re getting the best bang for your buck. Cheap green laser pointers can actually be more dangerous as it won’t be able to properly filter the infrared that could potentially be damaging for your eyes. One with a reasonable price and an IR filter is your best bet when choosing a laser pointer for stargazing.
Although laser pointers are available in many different colors, you should opt for a green laser pointer if you want to stargaze. Green laser pointers have the highest visibility among all colors. The brightness of the green laser makes it easier for you to see the laser beam in the middle of the night compared to red, yellow, orange, or blue lasers.
Adjustability / Range
For stargazing, you would need a laser pointer with a range that can cover a lot of distance. The laser pointer should also be able to accurately pinpoint the objects in the sky. Most green laser pointers for astronomy can cover a distance up to 3,000ft, depending on the model and brand.
You would also need to find a laser pointer that has an adjustable focus and a setting that allows you to alter the size of your laser beam. Make sure you set the focus and the size of your beam properly so that it can be more visible during the night.
Accessories (come along with your best laser pointers for astronomy)
Different laser pointers would provide various accessories in the package. Some would include a charger for its rechargeable battery and some would give a case for you to place your laser pointer in. Choose a green laser pointer that comes with all the necessary accessories for stargazing like a mounting system so you can easily attach it to your telescope.
Why are laser pointers great for pointing stars?
Most green laser pointers used for pointing stars are classified as 3A lasers and they have the power output of 5 mW or less. Depending on the regulations in your country, 5 mW is the limit for green laser pointers for casual use. That regulation is put in place so that laser pointers with higher outputs won’t be used casually, which can be dangerous for you and the people around you.
Laser pointers with a power output of 5 mW or less won’t be able to burn you easily. If you stared directly at the laser beam, it won’t damage your eye permanently. It means they’re completely safe to use casually without much of safety precautions.
The distance of the beam is also another factor that makes laser pointers great for pointing stars. While it’s quite impossible for a laser beam to reach into space, the laser would shine far enough into the sky so that you can pinpoint stars and planets. Many laser pointers can shine for thousands of feet into the sky, enough for you highlight celestial bodies effectively.
How to Use an Astronomy Laser Pointer
Using a laser pointer is extremely easy, especially if you’re opting for the pen-type laser for stargazing. They’re easy to operate and portable enough to carry around. A laser pointer is also easy to use once you’ve got the hang of adjusting its focus and mounting it to your telescope.
As a pointer
As the name suggests, a laser pointer’s main use is to point out an object too far for us to point with our hands. Objects like stars, planets, and satellites are obviously too far from our reach; a laser pointer is useful to highlight these objects due to their brightness and reaching distance.
As a finder scope
A laser pointer, of course, won’t replace the traditional finder scope but it can help you take note of the location of the stars and planets. With the laser pointer and your finder scope together, you can stargaze more quickly and accurately.
Some stargazing enthusiasts even prefer using a laser pointer by itself without the finder scope. This is because you don’t have to constantly bend down to use the finder scope and still point out the stars correctly.
Best laser color for Stargazing
Like mentioned above, green laser pointers are the best kind for stargazing. Generally speaking, green laser pointers are the brightest among all the laser colors so it’s really easy for you to see the laser beam in any kind of weather or time of day. It’s even brighter than the red laser pointers that we use for everyday use.
What contributes to the brightness of the green laser lays in its frequency or wavelength. If you want to know more about the different colors of laser pointers, take a look at the in-depth article explaining the differences between green, red, orange, yellow and blue lasers.
Also, always remember to avoid cheap laser pointers because they often lack the ability to filter invisible infrared (IR) that can be harmful to the naked eye. For more info on how lasers work in general, this article might be helpful.
Laser pointer safety tips
There are some safety measures that you should always follow every time you use a laser pointer to stargaze. These simple laser pointer safety precautions are:
- Double check on the laser class and make sure it follows the legal regulation
- Never point a laser directly towards another person
- Never point a laser towards a moving vehicle on land and airborne
- Turn on the child lock feature every time there are children around
- Do not aim the laser beam directly at a star; circle the stars instead
- Do not point the beam on a reflective surface
- Use safety goggles if you have a powerful laser beam
Buyers beware! Your best laser pointers for astronomy may be overrated!
You need to double check on your laser pointer’s power output because the warning label on some laser pointers might be incorrect. Make sure the warning label always signifies the class it belongs to and that the power output (milliwatts/mW) correlates with the class type. If the laser pointer looks suspicious, you may consider asking the manufacturer for a replacement.
Besides, we have hand-picked these laser goggles that can protect your eyes.
In a nutshell, laser pointers, especially the green ones, are a useful tool to have if you want to start stargazing. Do thorough research before buying yourself a laser pointer for astronomy. Pay close attention to the class and power output so that you stay within the legal limit. Compare different models of laser pointers and choose the one that comes with all the features that you’re looking for. Your next stargazing trip will be hassle-free once you’ve decided which laser pointer ticks all the boxes for your astronomy needs.
