Description

ABOUT THE OBJECT: Some facts from Wikipedia: IC 5146 is a reflection/emission nebula in the constellation Cygnus. The nebula is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago;, the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years.
IC 5146 is a stellar nursery where star-formation is ongoing. The biggest star in the nebula is BD +46 3474, a star of class B1 that is an estimated 14±4 times the mass of the sun.

Finally I can upload a new image since many months!
The season started with many clear nights in a raw and without the Moon! But the weather conditions were quite bad. Haze, fog, high clouds and very high humidity of course. The seeing was so bad that I could barely see the strongest stars.
Nevertheless I went out every night and collected photons (well the scope did it while I was sleeping, even if for only 3 hours). The 5th of September was clear too but the fog came to visit  my garden after just 20 min. that I started the session and did not want to leave until the morning. I had to throw away all the images.
Actually the fog was quite beautiful to see "dancing" every night farther down the hill until the 5th was not nice anymore I did not take a picture of it, but @Roy Hagen did it in Norway (some 400km from here), very similar to my view  from my garden!https://www.astrobin.com/cdtmu8/D/

The images where not so sharp cause the whether conditions, but I had so many of theme that I could select the less bad and make  something of them.
The stars where of course quite bloated and were  almost the most difficult part of the processing. Anyway, I don't want to take more of your time and hope that the image is at least watchable
Cs to every one!
