How to observe Orion Nebula and Andromeda Nebula?

M3 1 is a large nebula that can be seen by naked eyes on a clear moonless night. The search method is simple: look east from Andromeda alpha star to δ and β stars, then look north from β star to μ and ν stars, and then M3 1 will naturally come into view. M3 1 is also called Andromeda nebula, with brightness of 4.8 and apparent diameter of 160'×35'. You can also see its companion clouds M32 and M 1 10.

NGC752 (Andromeda)

Moving from Andromeda's V star (second-class star) to the triangle's beta star, a large star set will appear at the right end of the field of vision, which is NGC752. This is a large open cluster with a brightness of 7 and an apparent diameter of 45', which can be felt by the naked eye.
