Admit it. There's something vaguely disappointing
about sweeping up a group of stars that look like
a cluster, but turn out to be just a bunch of stars.
Millions of years of evolution have made us remarkably adept at ﬁnding order in chaos - an ability we
use when we see patterns in randomly distributed
points of light. Good thing, though, or there'd be
no constellations. Add binoculars to the equation and a whole new door opens for connecting
the dots. We call these asterisms - eye-catching
groups of stars that look like they belong together,
yet have no physical relationship to one another.
The diﬃculty with most asterisms is their very
existence often lies exclusively in the eye of the
beholder. I occasionally get e-mails from observers describing "incredibly obvious" asterisms that
completely elude me. But there are a few notable
exceptions. One of the most striking is Kemble's
Cascade, which lies in the dim constellation
Camelopardalis. Indeed, it's easily the constellation's ﬁnest binocular treasure. Camelopardalis is
so indistinct that the easiest way to ﬁnd Kemble's
Cascade is to start at Eta (η) Persei, then scan the
sky two binocular ﬁelds northeast of Eta.
Kemble's Cascade is a linear arrangement of
8th- and 9th-magnitude stars with a 5th-magnitude
sun at its middle. The chain is so distinctive I can
make it out in my 10×30 image-stabilized binoculars even from the suburbs. If you have dark skies,
inspect the eastern end of the cascade carefully.
There you'll ﬁnd magnitude-6.9 NGC 1502. In binoculars it looks like a single, 7th-magnitude star
enveloped in a compact haze. But unlike Kemble's
Cascade, NGC 1502 is a true cluster of stars. ✦
