Colour composite image (using g and r Sloan filters) showing NGC 1042 and its surroundings. Some known objects and a new identified galaxy (LBT1) are labelled on the figure for reference. The white and black background corresponds to the sum of the g and r filters to enhance the low surface brightness features. The white pixels correspond to the sky region while the darker pixels are the brightest regions. North is up and east to the left.
