Kemble's Cascade is a line of about 20 stars in the constellation of Camelopardalis. It is named after Father Lucian Kemble (1922-1999), a Franciscan friar and amateur astronomer, who described it in a letter to Walter Houstan as "a beautiful cascade of faint stars tumbling from the northwest down to the open cluster NGC 1502" which he had discovered whilst sweeping the sky with binoculars. Houstan was so impressed he wrote an article in 1980 for Sky and Telescope naming the asterism Kemble's Cascade.

I am pleased with this picture because I have captured at least some of the colours in these faint stars, something I have generally failed to do before. It was taken with my Canon 1000D DSLR camera fitted with a 70-300mm zoom lens set at 130mm. The cascade is the line of stars across the middle of the picture (move your mouse pointer over the picture to see it identified) and at its lower end is the cluster NGC 1502.
