The Cocoon nebula (IC 5146) is a beautiful reflection/emission nebula in constellation Cygnus. 
It has those reddish and blueish parts within the nebula as well as faint dust surrounding the field. 
It was quite hard to work out these faint dust regions, because i didnt get as much integration time as i planned (bad weather in Austria this summer). 
Presessing was done in PixInsight and PS.

366 Great American Eclipse+Robert Barsa+Slovakia

- Name: Robert Barsa
- Country: Slovakia
- Imaging target and date: Great American Eclipse, Aug 21, 2017

- Equipment used: 
optics: Skywatcher ED80/600 +HED 80W 0,85x flattener
camera: Canon 6D
mount: Skywatcher EQ-5
EXIF: ISO 100, exposures from 1/640 to 1,3 sec.

- Description: We need to travel, sometimes even to the other side of the world, to observe and photograph this magnificent phenomenon that can be seen only in the few kilometers wide path of the area called the zone of totality. 
Although the total solar eclipse occurs on average once in 18 months, it's always somewhere else and that area is really tiny compared to the whole Earth's surface. 
Next one in my country - Slovakia - will be in 2135
On this picture you can clearly see not only the sun's corona, it's structure and solar prominence (red), but even the surface of the Moon which is slightly illuminated by the sunlight reflected from the Earth.
- Digital processing methods: selection of 14 photos of the sequence processed in NAFE (Noise Adaptive Fuzzy Equalization, luminance only), 
Photoshop (manual alignment of frames), merge to HDR, Luminance and Color processed separately and combined later, final adjustments in Camera Raw
