Photo by Ivar Hamberg. Date: 2009-sep-19,26 and 2009-nov-21. Taken outside Stockholm, Sweden. Telescope 12" Meade LX200. Camera STL11000M. Filters S-II, H-alfa, O-III and RGB. Exposure times for SHO was 60 min each, and for RGB 20 min each. Image processing in CCDSoft and MaxIm DL. This area on the border of Cassiopeia and Cepheus is very interesting and shows several types of nebulous regions. The bubble is reemitting light from a star inside. The color palette used is similar to the Hubble scheme.
