Andromeda Naked Eye
The The Andromeda Galaxy is one of my favorite objects in the night sky
it is also the most distant object you can see with your naked eyes, two million light years away.
M 31 the Andromeda Galaxy is very east to find once you know the landmarks.

To use Cassiopeia
Look for the W shape of Cassiopeia. With the two V shapes that make up the W, use the V shape on the right. Imagine the V as an arrow, pointing into the constellation Andromeda. The arrow of Cassiopeia does not point precisely to Andromeda: You will have to look a bit to the right to find the galaxy M31.

From Pegasus
Start by first finding Alpheratz. Next calculate two bright stars to the left, and after that two fainter stars upwards. Andromeda Galaxy, M31, is right above the second fainter star
