Another new object (asterism) was introduced to me this month by the
December observing list. Kemble's Cascade (Kemble 1 from
a very small catalog) is an apparent straight line of stars intersecting the dim constellation Camelopardalis. The strange constellation name seems to be a Latin word based on three Greek words: giraffe, camel, and leopard (
Wikipedia). Sounds like a wonky animal to me!
Because the dim stars of the constellation were near impossible to see in my viewfinder or on live view, I pretty much aimed the camera in the general direction and took some 4 second exposures looking for the line. Once I saw it, it was very obvious! Like a little parade of stars!

Kemble's Cascade isn't an object in Stellarium, but it's located here relative to Camelopardalis in this screen shot. |
