Lens: FSQ106 f/5 Camera: QSI540ws camera Exposure time: 7 h in 900'' subexps for L, 4:30 h in 600'' for RGB and 3 h in 900'' subexps for Ha Filters: Baader filters Location: Ager, Spain Date: February 21st and 28th, 2009 The image subject is the region of M81 and M82 and their neighbors. We have tried to bring out the Integrated Flux Nebula as much as possible, and at the same time to preserve the small scale details in the galaxies. For the color balance, we have used the center of M81 as reference, assuming that its core is white, and after that it has been slightly corrected assuming that the integral flux of the whole image is pure white considering that the objects in it emits in the continuum.
