Kemble\u2019s Cascade is an asterism of more than 20 stars in the constellation Camelopardalis, with open cluster NGC 1502 at one end.<\/span><\/p>\n

This star pattern is not one of the formal constellations visible in the night sky, but is an informal pattern of stars known as an asterism<\/a>.<\/p>\n

Kemble\u2019s Cascade has at its centre, mag. +4.9 HIP 18505 and extends a degree from this star northwest and 1.5\u00b0 to the southeast.<\/span><\/p>\n

The main \u2018structure\u2019 is formed from stars between mag. +7 and +8 but fainter members down to mag. +10 help reinforce the straight-line appearance.<\/span><\/p>\n

It\u2019s best seen through a low-power telescope view and reveals some lovely star colours.<\/span><\/p>\n

Look for the two orange members in the northwest leg of the cascade.<\/span><\/p>\n

Locate the cascade by extending the line between Caph (Beta (<\/span>\u03b2<\/span>) Cassiopeiae) and Segin (Epsilon (<\/span>\u03b5<\/span>) Cassiopeiae) for the same distance again<\/span><\/p>\n

Kemble\u2019s Cascade is best observed on early evenings during November and December through binoculars or a small telescope and it will look like a vertical cascade of stars tumbling into the open star cluster<\/a> NGC 1502 <\/span>at the bottom.<\/p>\n

Use Kemble\u2019s Cascade to locate NGC 1502<\/strong><\/h1>\n

From Kemble\u2019s Cascade you can easily find NGC 1502, a mag. +5.7 open star cluster located at the southeast end of the line of stars that forms the cascade.<\/span><\/p>\n

Kemble\u2019s Cascade is often described as appearing like a waterfall of stars, pouring into a splash pool\u00a0 represented by NGC 1502.<\/span><\/p>\n

The cluster appears to contain around 25 stars through a 300mm scope, two of which are conspicuous because they are brighter than the rest.<\/span><\/p>\n

These are components of the double star<\/a> Struve 485, the pair being known as Struve 485 AE. The cluster has an apparent diameter of 20 arcminutes and is 2,700 lightyears away.<\/span><\/p>\n
