Description

After two nights of imaging the NGC7538 region , I found lot of red star halos and strange colors on my hardrive. A UHC filter and an older lens gave me the opportunity to train my image processing skills. Some focusing issues have eaten 3h of the overall 8h data. But the rich Cepheus region is worth all the efforts :-) I probably should acquire some proper RGB and reprocess the image.

Revision A shows the integrated and stretched image.
