How to observe nebulae?

1. naked eye observation, if large and small Magellanic clouds can be observed in the southern hemisphere in spring; Dark nebula coal pocket nebula (Sagittarius) can be observed in summer; M3 1 (Andromeda Extragalactic Galaxy) and NGC7023 (Cepheus Rainbow Nebula) can be seen in autumn, and M42 (Orion) can be seen in winter.

2. telescope observation depends on the size of the telescope. Beginners can use binoculars, and after a certain foundation, they can add small telescopes for amateur astronomers. In addition, you can contact the management of popular science work of the Observatory and use large professional astronomical telescopes for observation.

The preparations before observing the nebula are as follows:

1. Prepare a set of good-quality constellation charts, generally marked with nebula names, such as M (messier Table) and NGC (New Nebula Cluster Table).

2. A flashlight and a red cloth. The flashlight is wrapped in red cloth to reduce the light, because the observation conditions in the wild are much better than those in the city. However, due to the darkness in the wild, you can compare the constellation with a flashlight. In order not to be disturbed by the strong stimulation of light, red cloth should be used to reduce the light.

Pay attention to the cold, bring food and drinks when necessary, and it is best to have a simple seat, because I really want to sit for a while after I am tired of observing in the wild, and I have suffered losses before.
