M103 Cluster in Cassiopeia

I was not that great last night, imaged a couple of objects last night one being M103 in Cassiopeia. I only managed to get 15min worth of data before the wispy clouds moved in. 15x 1min, Flats & Darks applied:

Nicely framed and some great colours!

What is the other cluster in the bottom left?

[Deneb]

It might be NGC 457, 663 or some other as there are quite a few open clusters in that area according to TheSky.

Just about to send you a PM.
