-Sharpless 119 in Cygnus, project finalized
I have published three photo posts about my Sharpless 119 (Sh2-119) imaging project so far.
The first one was this photo at November 8, IMAGE LINK
The second one was a two frame mosaic, IMAGE LINK
The third one was a two frame mosaic in visual colors, IMAGE LINK
We have had very few clear nights at this Autumn season. I have managed to use them all so I was able to have enough data to finalize this six panel mosaic image of Sharpless 119.

A very high resolution photo of Sharpless 119, original resolution is about 12.000 x 8000 pixels.
Image is in mapped colours, from the emission of ionized elements, R=Sulphur, G=Hydrogen and B=Oxygen. The photo covers about six square degrees of sky. (The full Moon spans about 0,5 degrees of sky.)

INFO
Sh2-119, Sharpless 119, is a large complex of emission nebulosity in Cygnus constellation, about 2 degrees east of the North American Nebula. It is located just around 68 Cygni, a quite bright star of magnitude 5. (The most bright star in the photo) This target is not very commonly photographed due to a close proximity of brighter and well known targets, like North America and Pelican Nebulae.

Sharpless 119 can be seen at lower left corner. The white rectangle shows the location of my new mosaic photo. Sh2-119 spans about three degrees of sky horizontally. (The full Moon spans about 0,5 degrees of sky.)
This photo was taken with the Canon EF 200mm f1.8 lens and the QHY9 astrocam, Baader narrowband filter set at 2012.

Sharpless 119 in Cygnus, visual spectrum version
Since beginning of September we have had three clear nights. This Autumn season has been the worst in twenty years.
I made a visual color version out of my two frame mosaics of Sharpless 119 (Sh2-119). You can find a mapped color version from HERE. My aim is to make a six panel mosaic of the whole area of the Sharpless 119. At the moment it's not possible due to weather up here.

Sharpless 119 in Cygnus, project continues
I have published first photo out of Sharpless 119 at 8.11. 2017, since then we have had a full cloud cover. Yesterdat we had about three hours of clear skies and I was able to shoot an other frame next to first one. My target is to make a six panel mosaic image out of the whole Sharpless 119.

An other detail from the Southern Cygnus
This has been the most cloudy Autumn season in twenty years.
I'm still processing material from couple of clear nights we had this Autumn. I made another individual image out of the material, I shot for the WR 134 mosaic image.
