The famous Pleiades and their environment

Since September the sun has barely appear in our skies and the same is true for stars. So there were only three clear nights without a Moon, all three of which I was so lucky to image the sky. On December 16th I could do this picture with the well-known Pleiades, in a wide field setup.

I used the EQ8 with the old Nikkor 180mm F2.8 ED unguided. An IDAS 2″ filter in front of the objective was used resulting in an effective F/ratio of 3.8. However this seems to have affected the image quality. The star shapes are not ideal. 

20 frames of 300″ were stacked and processed by Jean Lammertyn in PI.
