what makes the colours apear like they are?

    the colours of this artifact are confusing as only half of this object has over 5 colours. unless there is something behind it i can not determine what it is... any ideas?

    Other zooites who have spent more time on artifacts than I have may be able to give you a more detailed answer, but I think the colors here are largely due to mis-alignment (e.g. the brightest pixel of the central source should be the same in all three bands, but isn't), and dramatically poorer image quality in at least one band (possibly due to much worse 'seeing' in that band, but more likely something to do with filter itself).
