Kemble's Cascade

Something unusual: A prominent deep sky object discovered with binoculars, in 1980. Well, not “object” in the traditional sense of a galaxy, nebula, or cluster, and not exactly "discovered" either. In 1980, the Canadian observer Lucian Kemble noticed this very pretty apparent tumbling of prominent stars across the sky after observing them through 7x35 binoculars. He sent remarks about the asterism to Walter Scott Houston, who published them in Sky and Telescope magazine in December 1980. Since then this succession of stars has been informally known as Kemble’s Cascade. Two other asterisms are also named for Kemble: Kemble 2, and Kemble’s Kite. (I must say that "Kemble 2" does not take any prizes for imaginative naming.)

Although the definition of an asterism is a “prominent” pattern of stars, in fact the stars in Kemble’s cascade are quite faint; they’re just much brighter than the other stars around. The Cascade lies in the northern constellation Camelopardalis (the Giraffe), and spans 2.5° degrees of the night sky, about five times the width of the full moon. The bright star in the center is HIP 18505; but again, “bright” is a relative term, since its magnitude is only +4.9. At the foot of the cascade is a beautiful open cluster NGC 1502, consisting of about 45 stars.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
