Choosing an Astronomy Grade Laser Pointer
Most amateur stargazers are keen to use laser pointers as an astronomy accessory. They are simple to use, but a lot of people are unsure of what specs make a good laser pointer for astronomy. Here is what to look for:
The power of typical lasers used for amateur astronomy is measured in milliwatts (mW). There are stronger star lasers that have enough output power to be measured in watts, but they are not for civilian use. A laser with output power levels of around five milliwatts is sufficient for backyard astronomy, and these are known as Class 3A lasers.
If you want an astronomical laser pointer, green is one of the brightest and easiest to see. With a green laser pointer, star gazing becomes a whole lot easier.
Color – What Is the Best Color Laser Pointer for Astronomy?
Laser pointers come in a range of colors which all have their own advantages. For an astronomical laser pointer, green is the preferred color. The human eye perceives green more easily than other colors in low light conditions.
A green laser pointer for stargazing emits a beam at a wavelength of 532 nanometers which suits our dark-adapted vision.
Most stargazers use green laser pointers. A green laser pointer with a lower power output will still appear brighter than, for example, a red laser pointer with a higher milliwatt output.
There are also blue-violet laser pointers suitable for night time observations. Overall, it’s unanimous that when choosing an astronomical laser pointer, green is your best bet.
But even if you don’t (or can’t) choose a green laser pointer and end up with another color, star gazing is still better when you don’t have to struggle to find what you’re looking for in the sky.
Astronomy laser pointers are available in several styles. The two main types of laser pointers tailored for astronomy are handheld pointers and laser attachments. A handheld pointer is very useful for group observations, like star parties.
It allows you to engage the group as a whole since everyone can easily see where to look. Laser attachments are mounted on to your telescope. With a green laser pointer, star gazing and locating targets is a breeze as you can focus in on objects accurately in no time.
There are also laser pointers with the ability to make focus adjustments by changing the size of the beam. It’s a handy feature as it can increase visibility in certain lighting and weather conditions. Keep in mind that an adjustable focus is optional since you would not normally want to be out observing unless visibility is good.
How Do Laser Pointers Work?
An astronomy laser pointer, or star laser pointer, is a powerful but surprisingly simple device. The most basic design of a good laser pointer for astronomy consists of a small circuit board and few components. The beam of an astronomy grade laser pointer can extend up to five miles in good conditions.
The beam essentially ends at the target star or constellation you are pointing at. This is why an astronomy laser pointer is so useful to amateur astronomers. You don’t have to struggle to point out dim objects like a needle in a stellar haystack.
With a laser pointer, night sky viewing is simplified for all involved and you spend less time finding your way across the sky. With a green laser pointer, star gazing is even more enjoyable, as green is the easiest laser light we can follow with our eyes.
The majority of laser pointers work by holding down a button to produce the beam. Newer models have features that keep the beam on without having to hold a button.
I prefer these designs because it makes the star laser pointer more effective to use when it’s attached to your telescope and your hands are busy positioning or steadying the telescope.
Laser Pointer Regulations and Safety
It’s so common to underestimate the potential dangers of using a star laser pointer. Some of the most common pitfalls are injuries and run-ins with the law. The light of an astronomy grade laser pointer is strong enough to impair vision and cause accidents for aircraft and vehicles.
Follow these precautions and regulations so that your experience using lasers is hassle-free.
- Commercial lasers are made to shine light onto distant stationary objects. They should never be used for pointing at another person, vehicle, or aircraft of any kind.
- Protect your vision by never aiming the beam of the laser pointer into your own (or another person’s) eyes. Flash blindness may result, and some lasers are strong enough to cause permanent damage to the retina. Also, avoid all contact with the skin. It is possible to damage skin by using a strong laser pointer incorrectly.
- Teach children that lasers are not toys and educate them on the dangers of lasers. Do not allow children to use a laser pointer unsupervised. Be sure to store your laser pointer out of their reach.
- Avoid directing the laser pointer at reflective surfaces. The beam may bounce back and inadvertently hit you or another person in the eyes.
- It is wise to use protective eyewear while using lasers, especially if you are new to using the device.
- Do not aim the laser pointer through the optics of binoculars or telescopes. This increases the intensity and range of the beam beyond what is safe and legal.
- Do not leave a telescope that is attached to a laser pointer with a “constant-on” setting unattended. It is always best to disable this feature before stepping away from your telescope, even if only for a brief moment.
- Commercial lasers are designed with a specific intention and safety in mind. These laser pointers come with cautionary stickers that specify their class and intended purposes.
A standard laser should be labeled Class 3A and no higher (Class 3B or 34). Do not purchase a laser pointer that does not have this safety information, and immediately report the manufacturers to the authorities.
A couple of years ago, the National Institute of Standards and Technology (NIST) conducted tests on commercial laser pointers. They found that 90 percent of the green lasers typically sold for uses like amateur astronomy did not meet safety regulations. These lasers exceeded power level restrictions, emitting double the power maximum specified by the law.
A number of poor-quality green lasers were also shown to emit harmful levels of radiation. Always choose a laser made with coatings and/or filters to confine radiation.
There are two more considerations when contemplating the use of a star laser pointer.
- Follow the rules of your star party group. First, get permission to bring a laser to your gatherings. Some groups prohibit the use of laser pointers and it’s always best to comply.
- You have to be outside a certain range of an airport to legally use a laser pointer. The standard is usually 10 miles from the airport. Phone your local authorities for the specific restrictions you must comply with.
These steps may seem drastic or unnecessary, but laser pointers have already come under fire for the dangers they can pose to aircraft safety and national security since the beams can follow aircraft in flight. It may seem like a fun idea to aim your laser at helicopters and boeings, but these actions can get you arrested!
A reliable green laser pointer for stargazing is still an underrated astronomy accessory. As the popularity of the device increases, so do the concerns about the use of lasers in non-commercial uses. It’s so important to be responsible when purchasing and using green laser pointers so that we can all continue to benefit from them in amateur astronomy.
My favorite one is the Higoo’s Military Tactical Hunting Green Laser Scope. Its quality stood out to me, as did its ease of use, high visibility, and efficiency.
I think it’s a great place to start if you are new to lasers, and works like a charm if you’re not. With your new laser pointer, night sky watching will be better than ever.
