Astronomy Laser Pointers – Green Laser Pointers for Astronomy

High power green laser pointers are becoming more and more popular for use in astronomy. Whether you are star-gazing with your astronomy club buddies or conducting an astronomy lecture outdoors, there is nothing more frustrating than unsuccessfully trying to identifying a star or constellation in the sky. Before portable lasers were available, the only ways were to either point to it with your index finger or describe the approximate position verbally. With new technology comes new hope for astronomers worldwide! By using a high power laser pointer, it is now possible to aim a visible laser beam virtually touching the star or constellation you want to point out. The era of astronomy laser pointers is here.

Green Laser Pointers for Astronomy

Green laser pointers are considerably brighter than all other visible color lasers because the human eye is most sensitive to the color green. At the same output power, a green portable laser will appear much brighter than either a yellow, blue or red laser. When we speak of the term “astronomy laser pointer,” it is most often associated with a green laser pointer.

Telescope Alignment with a Laser Pointer

Green laser pointers are not only useful for pointing out stars and constellations, it has other uses in astronomy as well. You can mount a green portable laser onto a telescope using its factory provided brackets (make sure to align the laser parallel to the telescope). If brackets are not available, you can just hold the laser down using your hands. A green laser pointer mounted on a telescope can make aligning the telescope to objects in the sky much faster and easier.

Power Output

Green laser pointers come in a variety of power output ranging from 1mW to 500mW. Which one is suitable for astronomy? More specifically, which is most suitable for your needs? What power output should you choose?

1) A 5mW green laser pointer has a bright laser end “spot”. The actual laser beam is only faintly visible. These are more suitable for presentation purposes and not astronomy.

2) A 15mW – 75mW green laser pointers emit a bright laser beam making them a good choice for astronomy.

3) At 95mW – 150mW, the green beam is even brighter offering extreme brightness, visibility and distance.

4) As you increase in power output, the laser beam will become brighter and more solid in color. The best suggestions if you are looking for an astronomy laser is to purchase something you are comfortable with paying.

5) SKYlasers offers power adjustable lasers where you can adjust the power output between a high-power and low-power setting.

Warning

Do not point any laser pointer devices at any flying aircrafts in the sky; it is a very serious offense in most countries.
