Komorow, Poland

The M52 is a nice open cluster in Cepheus.

The entire area is full of faint Ha glow, and the Bubble Nebula is the brightest part of this glow.

The difference of brightness between the bubble and background is significant, so I had to reduce overall contrast by using layers and masking. Stars were a bit blurred to reduce pixelization.
