Which season is best for observing constellations?

It depends on what constellation the landlord wants to observe.

There are different constellations in each season, such as Ursa major in spring; For example, the summer triangle in summer has the largest number of stars in the sky in summer, such as the Milky Way and Cassiopeia in autumn; And Orion in winter, the big triangle in winter.
