Green Laser Pointer — The Best Gadget for Astronomy Hobbyists


It is a well known fact that green laser pointers are multifunctional and they have many specific applications in astronomy, presentation and burning areas. Generally speaking, people who purchase laser pointers all have their particular purposes and they hope that laser pointers can bring fun and convenience to their life.
People who want to stargaze with lasers make up a large proportion of the laser buyers. Well, green laser pointer is actually a pretty good tool for watching stars and other celestial objects. Green laser pointer is clearer than red, blue and violet lasers. That’s because human eyes are more sensitive to green than other colors and people can see further and clearer with green laser beam in the dark.

It is quite convenient for astronomy enthusiasts to stargaze by holding green lasers in the hands. Pointing at a unique star to people around them is quite convenient and time-saving, and astronomy lovers do not need difficult explanations and gestures any more. Besides, green laser can be mounted onto the telescope by a bracket and the beam clearly shows where the telescope is pointing and the object being viewed through the telescope. At the same time, a green laser mounted on the telescope also makes aligning the telescope to a celestial object much faster and easier.
People tend to choose high power green lasers for the astronomical activities and it is becoming some kind of fashion in modern days. However, there are two conditions for your consideration about the power selection. First, when you are alone and a low power green laser such as 5mW is enough and appropriate. Second, if there are many people stargazing with you, a high power laser such as 100mW is a good choice. So do not blindly pursue high power or low power and people should make right choice according to specific conditions.
Safety issue is quite critical to astronomy hobbyists and other laser users. They should wear laser safety goggles with high power green laser pointers and do not look directly at the laser beam.
