Filaments of the Veil Nebula
At this Autumn season I have shot several well known targets in constellation Cygnus.
My purpose was show them little differently by selecting some less imaged details to show.
This new image is a four panel mosaic showing the complex, filament like, structures in Veil Nebula supernova remnant. Original full resolution photo is about 11.000 x 4000 pixels! Total exposure time is around 35 hours. The final photo looks like a giant alien space plant...

Pelican Nebula, a two frame mosaic
At November 30 I published a new photo about dark filaments between North America and Pelican Nebula. Later I found out, that my shot was overlapping with my older photo of the Pelican nebula. This image is combination out of those two images.
