The Crux constellation and the Coalsack Nebula (C99) captured with an old DSLR.
My Nikon D5000 have a serious issue with its sensor. On the right corner and top of the image we can see it failure. A region of the sensor which does have a lack of sensitivity.
First I though it was a "flat frame issue", but it's not. Darks and bias doesn't help.
Only after a carefully processing I'm "ok" in posting this picture. But my Nikon D5000 is old, and I'm not happy to say that it needs to retire.
