Came out much nicer than my previous attempt even though I used the exact same setup and took it from a more light-polluted location. Still lots to improve.

Very nice. Also known as the Seven Sisters but normally you can only see six. I think there's a star in your photo which could be the seventh.
Do people call this the little saucepan/pot/dipper? Here in the Southern Hemisphere (Australia) many people call Orion "the pot" because it's upside down here. So this constellation can be called the little pot. You have the Big Dipper of course, which we can't see.

There's actually nine named ones. In addition to the sisters, their parents Atlas and Pleione are actually two of the brightest seven. Asterope and Celaeno are the eighth and ninth brightest stars

Got home the other night, it was particularly clear outside, daughter walks to the front door and I look up and stare at the sky for a moment. Look around for a minute then I said "oh hey look Pleiades". She said "Dad, Pleiades open the door".
