A collection of images from a large mosaic of Cygnus

I haven't been able to open up this season yet, since some of my equipment are not yet back from the factory service. (Should be here any day now!) To keep up my processing skills, I have reprocessed my older material.

All images are reprocessed and fine tuned. Images are shot wit a Canon EF 200mm f1.8 monster lens.

This lens is very sharp from edge to edge at full open.

Some parts of the mosaic are boosted with longer focal length instruments, Tokina AT-X 300mm camera lens and the Meade LX200 12" SCT-telescope. QHY9, a cooled astronomical camera, is used with all instruments. All photos are in narrowband colors, from an emission of ionized elements, Hydrogen, Oxygen and Sulfur. Baader narrowband filter set is used for the emission line imaging with all the instruments.

Reprocessed, NOTE. a large image 2300 pixels wide and 4.3MB

Image is in mapped colors from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen. Native size of this image is over 15.000 x 10.000 pixels.

Please, pay attention to a resolution of images bellow. I have used a new processing technique of mine to keep images sharp during the processing routine.
No artificial sharpening methods are used!
