There is nothing more frustrating than trying to determine in astronomy to be successful, an object in the night sky to a companion waving his arms, fingers point, and describe gestulating. An elegant and very effective simple solution to this problem is to use the green laser pointer to indicate the objects in the sky.
green laser pointers are high technology gadgets, astronomy and more popular. Not only are green laser pointer is ideal for detecting celestial objects, but are also very useful for aligning telescopes and for atrophotography.
Why green laser pointer
green laser pointers are the preferred laser pointer color for astronomy because green is the color most visible laser pointer. The reason why green is more visible to the human eye is more sensitive> Light Green. The other reason is the effect of light in Earth's atmosphere. The light is visible in the sky when the atmosphere and scattered wavelengths scattered more than green wavelength higher. It is a medium wavelength so it scatters more and more visible wavelengths as red.
Other applications
With green laser pointer stressed people celestial object next to you is not the only application forLaser Pointer for astronomy. A green laser pointer can also be mounted on the optical axis of a telescope with a bracket or the laser with his hand in the groove parallel to the telescopes. The green laser pointer beam clearly shows where the telescope and show the object that is seen through the telescope.
A green laser pointer mounted on a telescope can also makes aligning the telescope at a celestial objectmuch faster and easier.
What should be laser pointer?
green laser pointer can therefore range of power levels from 1 mW to 200mW decide all such use to which power can be difficult. The points that the choice of a high power laser for astronomy are
-The number of people watching stars with you. If there is one person, a low power such as 5mW is suitable. If you are a large group to observe the starsPeople do not need the laser to the next most visible, high performance, it would probably 100mW Sun
-The amount of ambient light. If you watch the stars at dawn / dusk, full moon, or in areas where until they are a lot of light pollution, a low-powered beam to be built as 5mW hard to see. They usually need at least 50mW or more in such a situation.
Superior laser pointers are not always the best enginebecause each reflection can easily ruin the night vision and can be a distraction. Many nights stargazing been ruined when people were more attention to new and exotic high power laser used to detect objects as real objects
Caution
shows a laser deliberately grounded aircraft is a very serious offense in any way to avoid looking star near airports and not a laser, when a planein the section of sky watching.
