Fantastic, but what about blue cloud?
This is a fantastic image. An artist's impression couldn't beat this. There is also a bright blue linear feature running up and down the image that looks like it could be comprised of cosmic ray hits on the CCD. But there is also a blue cloud, very faint, to the left centre edge of the image that looks different, more like a loose gas cloud or something. Could this be a voorwerpje? Or is just related to a cosmic ray hit?? The cloud is best seen in the "view image" window
it is an artifact of i-don't-know-what but it is not cosmic ray hit/gas cloud/voorwerpje.
