Galaxies

Some views of the real outer space. Since my maximum focus lengh is around 550mm, most of the galaxies are shot with a very small scale. Anyway I’m always trying to get a good impression of these objects. Of particular interest for me are pictures with local objects of our galaxy and a real deep sky 0bjects. An example is the pic of NGC6946 and NGC6939. I collect this type of pictures at Close Encounters.
