Bright nebulae of the central Cygnus, eleven panel mosaic finalized
My first photo session for the year 2017 was at January fourth. As a result, I was able to finalize my mosaic image of the central Cygnus. It has now eleven panels stitched together seamlessly. I have made two versions, as usually. This one is in mapped colors and another, yet unpublished, in visual spectrum.
Mosaic images can be highly work intensive but the final resolution is great. They are very suitable for extreme large prints. Original resolution is around 20.000 x 9000 pixels.

red=sulphur, green=hydrogen and blue=oxygen. A mosaic image with seven panels. Original image has a resolution of about 20.000 x 9000 pixels. Image spans about five degrees of sky horizontally.

The Sky on Fire, Mosaic of the central Cygnus
A three panel mosaic in visual palette, combined from narrowband channels, shows a three degrees patch of the central Cygnus gas formations. I have published a mapped color version few days ago, it can be seen HERE.
