A lot happening in this little section on the border Cassiopeia and Cepheus. There are a number of open clusters including M52 and NGC 7510, emission nebulae everywhere that includes from left to right, IC 7510, Sh2-157, NGC 7538, and NGC 7635, the bubble here is caused by strong stellar winds from a young hot star. There is also a bipolar planetary nebula that I had no idea was there until I ran the image through
astrometry.net, its called KjPn 8 and I've blown it up in the upper right!
