How can I choose the best astronomy green laser?

Using an astronomical green laser when stellar forces help you identify different constellations. Before you choose a laser indicator, you may want to think about the conditions you use it, because the weather, time of time and air pollution may affect visibility. If you are looking with a group, you will need a stronger device than if you do it yourself. Some models connect to the telescope and one of these green lasers can be a good choice if you also plan to use this device. There are laser indicators ranging from 5 MW to 150MW and there are many different intervals. Generally speaking, the higher the number of MW, the more accurate the device will be, especially if the weather is bad. Green high performance laser may also be more expensive, so you may not want to buy one of these models if you are going to walk regularly.

Some laser indicators are designed for personal use; Many of them can also join nand a belt or keychain. Astronomical green laser, such as this, can only be rated 5MW. This can be a good choice if you plan to stargaze yourself from time to time. Keep in mind that the laser indicator with this low rating can only be useful if there is very small light pollution in your area. The one that is rated 10 or 20MW may be better in this case.

If you are planning a star with a group of people, you may want to think about a greater laser. The green laser, which is around 50MW, could be ideal for two or three individuals. If you are part of a larger group, you may want to consider one rated at least 100MW. If you use a telescope, you may want to consider a model that can be mounted on this device.

Green laser astronomy is generally the most effective when used in complete darkness. If you plan to use only a laser indicator at night, a lower power from 25 to 50 MW may be enough. If you are on duskOr Dawn, you may need the one that is at least 100MW. This is especially true if the area where you follow the constellation has a large amount of air pollution, as it also tends to reduce visibility.
