Image Description and Details : In the summer months we can capture the wonderful nebulae region in the constellation Cygnus. In this frame the beautiful Crescent nebula and the material from the hot star WR 134 with their surroundings can be seen in full glory. The image is a combination of Ha data and Oiii data. The data was captured from the backyard in the Netherlands.

I have started this imaging project back at 2010. My aim was to make a high resolution mosaic covering the constellation Cygnus. Work like that takes time and patience, especially since I have worked so, that many of the individual sub mosaics or frames have been published as an individual artworks. Here is a poster format presentation about all of longer focal length images used for this mosaic beside wide field panels.

As a result I have now a huge 37 panel (And 58 long focal length sub-panel) mosaic panorama covering 28 x 18 degrees of sky.  I have collected photons way over 600 hours during past ten years for this photo. The full size mosaic image has a size of about 25.000 x 15.000 pixels.

In the orientation image above, there are three large supernova remnants visible, first the Cygnus Shell W63 , bluish ring at upper left quarter, secondly the large SNR G65.3+5.7 at utmost right and finally the third is a brighter SNR, the Veil nebula just outside of field of view at bottom center. (Image is partly overlapping with large mosaic but I didn't want to include it yet due to artistic composition.)Beside three supernova remnants there are two Wolf Rayet stars with outer shell formations. NGC 6888, the Crescent Nebula at center of the image and the WR 134, it can be seen as a blue arch just right from the Crescent Nebula, near the Tulip nebula.Next to the Tulip Nebula lays a Black hole Cygnus X-1, it's marked in small closeup image of the Tulip Neula at center right in orientation image above.

There are 37 base panels with shorter focal length tools (300mm f2.8 Tokina and 200mm f1.8 Canon) There is also 59 sub-panels used, they are shot with my old 12" Meade and 11" Celestron Edge scopes.

Image Description and Details :

Part of the Cygnus constellation, the crescent nebula is located in the immediate vicinity of the star Sadr. Its atypical shape also gave it the name "Euro Sign Nebula" (currency).
On the left is visible the "Soap Bubble nebula", discovered only in 2007 by amateur astronomer Dave Jurasevich.
The image is a composition in the HOO palette, with an exposure time of 37 hours.
Setup DDM60 mount, Moravian G3-16200, Takahashi fsq85.
