Help finding something

[zikalify]

So a few years ago when I started doing amateur astronomy I remember using a list to find things to look at in the sky, one of the things on the list (I think) were there 20 or so stars that are in a line (I'm not thinking of the hydra constellation). I haven't got a clue what it's called although the word 'castle' comes to mind when I think of it, no idea why, it might sound like it or contain some of the same letters. I think it is a summer object or something you'd see in autumn. Anyway If you know what I'm trying to remember drop a comment below.

Possibly Kemble's Cascade?

Glad I could help.

I bet this is visible as this time of year Cassiopeia is high in the north east... lovely sight, first time for me earlier in the year.
