I am usually not spreading the nonsense I see at various conspiracy sites, but this one IS puzzling. Go the official FITS astronomical image viewer at: http://hla.stsci.edu/cgi-bin/displa...6w_v1&autoscale=&title=Ison+130430+WFC3+F606W and zoom out 2 or so times to get comet ISON in view. Now click on the "darker" button 2 - 3 times, zoom around a little. Look at the comet. You get this: Obviously it cannot be the scope's cross-hairs since they would not be surrounded by dust. Imaging anomalies due to long exposure??? All the other stars etc. in the images look normal. Dafuq is this?
