How to find the Andromeda Galaxy

For those of you who are like me, and like to go outside at night and look into the sky and find different things and just star gaze to see what you see then here is something that might be fun for you to do.
Andromeda is called M31
Here is how to find the Andromeda Galaxy:
1. Go to a place where there is little light, in the city (Riverside,MorenoValley) you mostlikely will not see it with you un-aided eye, so go somewhere dark enough, I dont care where you go, just go.

2. You will need to find three constellations:
  • Pegasus- the great square of pegasus is easy to find,it is one of the easier to locate of the three, as it looks like a giant square
  • Cassiopeia--is even easier than pegasus because it looks like a "W" or "M"
  • Andromeda lies between Pegasus and Cassiopeia
3. On Pegasus locate the brightest star on it. The one that is closest to Cassiopeia.
This star is called Sirrah

5. Next to this bright star, look in the direction toward Cassiopeia and a little down.
You will see a fainter star.
6. Next to this star, look in the direction toward Cassiopeia again, and a little down.
You will see an even fainter star. (this star is called Mirach) (careful this is where your eyes might play tricks on you if your not using binoculars, or the sky is not dark enough)
7.  Now from Mirach, you will see a star just above it, this star is called mu Andromeda, and it is even fainter than Mirach. (If you are not  using anything, it is difficult to see, but you can see it!)

8. from mu andromeda look just above it and you will see a fuzzy, cloud like object, this is ANDROMEDA!


 
I didnt use binoculars the second time I searched for Andromeda, and in order for me to follow the faint stars I had to look to the side and not at the star itself, maybe its just me, but his helped when I was looking at Andromeda, and the faint stars.
Side NOTE:
  • If you look carefully in binoculars or a telescope, you may find two faint fuzzy spots beside it. One of them, M32, is smaller in size and closer to the actual galaxy core. The other, NGC 205, is more elusive, larger in size, and farther from the actual galaxy. Both are companion galaxies to Andromeda.
  • You will probably be able to find it if you use a GOTO or computerised telescope. If you use an equatorial and know how to use setting circles, the Galaxy is at RA 00h43m, DEC +41deg16' .
If you have any questions, about finding it please email the professor not me!
