ARE YOU TIRED of ending long summer days with "Down and Out With Donald Duck" or some other cartoon special you recorded in March, followed by bathtime blues and sibling strife? Try raising your sights before razing your homestead.

Look to the stars.

Although there is no star cluster that looks like Donald or any other duck, there's a swan. Also a bear, a giraffe, a lion, a dragon and a big spoon. And a little spoon.

There is even a letter of the alphabet to remind preschoolers of "Sesame Street." You can almost hear Oscar the Grouch saying, "The sky tonight is brought to you by the letter W" (or M if you're standing on your head.)

The night sky provides myriad entertainments for those who know where to look.

Children will be better prepared to gaze at the stars if they've first been introduced to them by a show at one of the many local planetariums -- or just by looking at pictures in a book. There are star-finders (wheel-shaped charts that indicate which stars are in our sky during which months) available at the Smithsonian's Air and Space museum and lots of star maps with the lines of the constellations drawn in -- like dot-to-dot pictures.

Binoculars are a big help in locating stars, says Steven Smith, director of the Arlington Planetarium. Pick a clear, moonless night, soon after sunset, so that only the brightest stars are showing. Spread a blanket and close your eyes. Allow about 10 minutes for your eyes to adjust to the dark.

Taking our courage (and our blanket) into our hands, my husband and I led our stargazers, Wynken, Blynken and Nod-Unless-You-Make-Me, out into the backyard dark.

While we were waiting for our eyes to adjust, Emily, 3, began to whimper.

"What's that noise?" she asked, fearfully.

"That's just Daddy snoring," said Adam, 7. "Are we going to tell ghost stories?"

"We're going to tell star stories," I explained. "Each twinkly little star you see up there is really a huge, hot sun. Although the constellations appear to move through the sky at different times of the year, they stay the same distance from each other. They are very far away. So far that we have to measure their distance in light years."

"What's a light year?" asked Ben, 5.

"A year in which we don't have another baby," said his father, rousing briefly.

"Light," I said, paraphrasing one of the astronomy books I had borrowed from the library, "moves faster than anything. It can travel 5.8 trillion miles in a year -- that is called a light year. Light from the sun reaches us in about eight minutes. When we look at a star like Polaris, the North Star, we are seeing what it looked like 450 years ago."

Seymour Simon, author of "Look to the Night Sky" suggests stargazers start by trying to locate one or two constellations a night. All stars in a given constellation can be located without turning your head, he writes, but remember, they're much bigger than you envision them from a picture.

Start, Simon says, with the Big Dipper, which is right overhead. From there you can find Polaris by drawing an imaginary line between the two end stars in the dipper's bowl and continue it until you come to the North Star. Polaris is the last star in the middle of the Little Dipper.

My children, after some pointing and arguing, found the Big Dipper and Polaris.

"Now," I said, "the handle of the Big Dipper forms the top of the head and the back of the neck of the Great Bear."

"I don't see a bear," complained someone.

That's precisely the problem most beginners have, says Smith.

"People expect too much from constellations," he added. "They think they're going to see Michelangelo up there."

"Is there a Great Bear story?" asked Emily, a fan of Goldilocks and the Berenstains.

"Sure," I said, consulting "Find the Constellations," by H.A. Hey, with a flashlight. "There's a Little Bear, too."

The Roman myth goes like this: Jupiter, king of the gods, was married to June. In spite of that, he married other women. Understandably, June tried to harm his other wives. One of them, Callisto, bore Jupiter a son, Arcas. June turned Callisto into a bear and ordered her to roam the forests forever.

Arcas grew up to be a hunter and nearly killed the bear who was his mother. Jupiter intervened and turned Arcas into a small bear. He placed them side by side in the night sky, where they can always be together.

"The Little Bear," I told the silent kids (perhaps they were imagining being turned into bears) is also the Little Dipper."

To find the W, which is also called Cassiopeia, draw an imaginary line from the handle star nearest the bowl of the Big Dipper to the North Star and an equal distance beyond. The line will reach a group of stars that looks like a "W" or the points in a queen's crown.

In between the Big and Little Dippers, Simon says, are some bright stars in a row. These are the tail of the Dragon.

Follow the stars on around the bowl of the Little Dipper, across the back and up the neck of the dragon to a triangle of stars that forms the dragon's head.

To find three of the brightest, or first magnitude, stars in the summer sky, which form the Summer Triangle, draw an imaginary line through the first star in the handle of the Big Dipper, past the dragon's head, to a brilliant blue-white star called Vega. Vega, in the constellation Lyra (the Lyre), was the first star to be photographed (in 1850). The other stars forming the triangle are Deneb, which is in the tail of Cygnus (the Swan) and Altair, the middle of three stars that make up the head of the Eagle, which was Zeus's pet eagle, before he put him in the sky.

"The swan looks like a cross, the eagle looks like a teardrop or raindrop and the Great Bear looks like a saucepan," Smith says, explaining how he is able to make out their shapes.

Earth and our solar system and millions of stars belong to a galaxy called the Milky Way. The edge of it can be seen most brilliantly in July and August, Smith says. It looks like a cloudy path through the dark sky, straight up south and down through the north.

"Milky Way!" shouted Adam, when I mentioned it to him. "That's a candy bar!"

"I'm hungry!" chorused the stargazers.

"The kitchen is closed," I said, "but I will talk to you about Mars. And Venus, Jupiter, Saturn and Mercury, the five planets that are occasionally visible without a telescope."

Unlike the stars that appear to be fixed in position, the planets wander. They wander, Simon says, in generally the same path as the sun and moon.

During the summer, any visible planet will be low in the southern sky, Simon says. They do not twinkle like stars, as their light is a reflection from the sun. Venus is silvery, Mars reddish, Jupiter white, and Saturn yellowish, although the colors usually cannot be seen without a telescope or binoculars.

The surface of each planet is different, too, I told the kids, quoting Hey:

Earth is the life planet. Mars is so cold that even Martians couldn't live there. And Jupiter, the biggest one, has a surface covered with miles of frozen ammonia slush.

"Yuck," said Ben.

"Not necessarily," said Adam. "It gives me an idea. Even if the kitchen is closed, we could go out for a Slurpee."

It seemed a fitting way to end the first experience with the night sky.
