Following points should be considered before a skywatch:
1. The place for sky watching should be away from the city and as far as possible it should be new moon night.
2. Binoculars or telescopes should be used for skywatching.
3. Identifying the pole star in the north makes the skywatch easier. Hence the pole star should be used as a reference point for skywatching.
4. As the stars in the west set early, sky watching should begin with stars in the west.
