Kemble's Cascade (all night)

Kemble's Cascade, named for Canadian astronomer Father Lucian J. Kemble, is a gorgeous string of 9th and 10th magnitude stars located in the northerly constellation of Camelopardalis, the Giraffe. Look for the magnitude 4.95 star named HIP 18505 shining midway along the cascade's 2.5 degree span. Any size
of telescope will reveal more details. Some of its stars are blue-white,
others are white and golden. Quite a few are pairs arranged at right angles to the main NW-SE cascade. Near the southeastern end of the cascade, look for the unrelated open cluster NGC 1502. Its core is dominated by the magnitude 6.9 stars of Struve 485, which are 17.7 arc-seconds apart. From a dark site, you may be able to see that magnitude 6.0 cluster with your unaided eyes.
