Asterism: a grouping of stars that form a recognizable pattern.
Constellation: Camelopardalis
Right Ascension: R.A.: 03h 57m 04.0s
Declination: +63° 04' 00"
Magnitude:  5 to 10
Size: 2° 30” 

Found in the constellation Camelopardalis is a line of about 20 stars in a straight line that ends at NGC 1502, an open cluster.

Finding the constellation will be a challenge since there are no bright stars. Look for Polaris, Capella and the constellation Perseus. Camelopardalis is between those, as shown at right.

Look for the chain of stars as shown at left and follow it to the open cluster NGC 1502. Since this asterism is over 2 degrees long, you will have to follow the stars in the eyepiece. Or better, look for it in your finder or a pair of binoculars. 

This was discovered by Father Lucian Kemble but named by Walter Scott Houston in his column “Deep Sky Wonders” in Sky & Telescope magazine. Read more about the asterism in Wikipedia. Wikipedia Kemble's Cascade.

This object was on the Astronomy Picture of the Day (APOD) in 2000.
