Description

For getting some more definition and more signal I dediced to spent this image some more luminence data. For the core area structure some very short exposures were very helpful because it's bright enough. I think I can not get a better version with my edge of that iconic galaxy. Hope you like it.

CS, Christoph

Description: Every year I add some data to that pic. This time luminance data of my CT 10, to get more of the background stars and galaxies as well as the tidal streams.
