Kemble's Cascade (Kemble 1) a Straight Line of Stars Through Camelopardalis

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!
