Processed by Jean Lammertyn in PI, so I did only half of the work.

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.

Lots of stuff can be seen on this picture: not only the Pleiades ("Seven Sisters, daughters of Atlas) and their surrounding blue reflection nebulas, but also the "Interstellar Flux Nebula" of IFN, which is all of the dusty filaments in grey that almost fill the picture, these nebula do emmit light themselves, but merely refelect light from nearby stars.  Some red patches of luminous hydrogen gas show up.  

I'm happy that with a limited integration time, this kind of result is possible from Hoegaarden. Earlier attempts in processing from my side were not nearly as good as this one! Thanks Jean.
