From the Bubble to Cave nebula area
Yesterday I published a panoramic photo of constellation Cepheus, there is new material in upper left corner area of the panorama. I made an individual composition out of this interesting area, dark clouds of gas and dust are shadowing light from energetic emission areas. Bubble Nebula can be seen as tiny pearl like formation at middle left. Near the Bubble lays much large Sharpless 157, thae bright area at lower left. Cave Nebula is located to upper right area of the photo.

Photo is taken from downtown Oulu, Finland. Due to an extensive light pollution I can do only narrowband imaging in my location.
Total exposure time is around 20 hours.
