What is the difference between different power green laser pointers

Some devices provide this feature and provide a level of beam control that other devices simply cannot provide. Whether you use it to increase the burning capacity (focus the beam to increase the intensity), or accurately locate the target at a greater distance, you can control it well. There is nothing better than using a laser beam to use a telescope to focus, gaze, and aim at a single body in the night sky. If you are interested in stargazing or astronomy, using a handheld laser will make the experience even better. Not only can you pinpoint the constellation or other parts of the sky, you can also show the audience clearly what you are looking at. If you point your finger in the direction, it may be difficult for others to understand exactly what you mean (after all, there are seemingly countless stars in the night sky). By using a laser, you can make it straightforward when you shine directly on the body you are discussing.
