Well, maybe we might need help from our constellation chart.

(Avianna) Good idea!

The star charts are like the map of the sky.

They just help you know which star is part of which constellation, so that you don't get lost.

But remember, it's dark outside, so...

So we need our... headlights.

(Miranda) We use red lights when we're stargazing because our eyes aren't as sensitive to the red lights as it is to the white lights.

(both) Bidle-bidle- bidle-dah!

(laughter) (Tina) When you have a map of the ground, you hold it on the ground, then you look in your directions-- not at the sky.

What do you do?

You can't look at it this way.

You have to point it upwards.

Oh, that makes sense.

That makes sense.

We're going up.

Okay.

Yup, I'm lookin' up.

Whoa!

Whoa!

Ah, I'm okay.

(Tina) So now you got 1, 2, 3.

Does that match?

(Avianna) Yup.

We looked for the Summer Triangle because it's very easy to find.

And there's one bright star right there.

So we can find the brightest star to the left.

(Avianna) Yeah, west.

(Miranda) I think I found it.

(Avianna) Yeah, I found it.

(Miranda) So that's Vega.

(Avianna) Look, there's all Altair.

And there's Deneb.

(Izzie) Yeah, I can see that!

Wow!

(Miranda) Once we find the Summer Triangle, we see Deneb, then we know that Deneb is part of Cygnus, so we can already start the star count.

Limiting magnitude 1.

"No stars in the cross are visible."

I say I can see more than that.

Yeah, me too.

Limiting magnitude 6.

"S-shaped curve of stars visible."

(Avianna) Then you could see this "s." See the long tail.

Yeah, you can see how faint the star is.

You can see a star.

(Tina) So you got this s-shape, so past limiting magnitude 6.

So then we must be on 7.

(SciGirls) "Too many stars to count."

(Izzie) Too many!
