Joe,
Some folks have claimed such is an artifact of the imaging systems.
Given all the noise on the net about it being real . . . I’m a little skeptical it could be dust on a lense.
Give your expertise in such things . . . what’s your best guess?
wha’t with the high pass flter image?
Does this prove or disprove that the image was photoshopped?
(serious question)
Here's the original image from the SKYVIEW QUERY FORUM, with DSS2 Blue Optical Survey selected with coordinates 16 19 35, -88 43 10 :
The unseemly mess is evidently an artifact, since it does not show up on the DSS2 Red image of the same coordinates. Of course this is why it is such a pure blue.
The earliest blog references to these "spaceships" that I saw are from March 2010, and I surmise that the story originated with some UFO enthusiast perusing the SKY-MAP site.
