I wondered this night why Christian insisted to put this nebula at the top of the
CCD-field. But if you look carefully, you can see a tiny little stria pointing to the
south of the image. It is very weak.
This variable Nebula changes its appearence very often due to some dark clouds rotating
around the bright star at the center. It must be interesting to image it twice a year and
make some animated gif.
