If anyone is interested apart from Robert, the European Southern Observatory (ESO) through the astronomer Olivier Hainaut has graciously supplied me with raw images of the Carina Dwarf taken with the 2.2 metre MGP/ESO and 4 metre Victor M Blanco scopes in Sth America.
Olivier's activities have included ultra deep imaging on 6 and 10 metre scopes and extensive experience with image processing.
Since this activity is an exercise in science and not in the production of a pretty picture there are some strict guidelines.
(1) No sharpening
(2) No contrast enhancement.
(3) No colour saturation.
(4) No photo-shopping etc.
The raw image will be stretched and the pixel mapping routine applied.
The image will be compared to other ESO images of the Carina Dwarf and carefully scrutinized for artefacts.
A very big thanks to Olivier and Lars Lindberg Christensen.

Steven
