Strange lights on photos from observing night sky.

    I'm just back from a brief visit to Sweden where I had an opportunity to go out of the city to try and observe the aurora borealis. Alas there was nothing showing that night. However I set up the camera and took a good few shots of the sky. On looking at the shots later I noticed some strange lights on the images. At first I though they were dirt on the lens, but looking at a series of shots I took every 15 seconds they seem to behind clouds as they drifted by. I'm not too sure if it is a camera atrifact or an atmospheric phenomena. There's no dirt marks / dust on any of the other shots from the night. Has anyone any ideas thoughts etc... Full images and crops below

    It certainly seems like like some contamination on the lense. The bottom one in the second photo looks like some refracted light that's out of focus. The different camera settings and bright light in an otherwise dark scene probably accentuated the effect.

    Meanwhile, here's one I took from the Gravity Bar at the Guinness Hop Store on Sunday evening.

    Artifact. I guarantee if you join the 3 main artifacts with lines and the 3 lights where the people are, and measure the angle subtended it will be exactly the same for the artifacts and the real lights. The fainter more elongated one to the right of the main three is related to the reflective strip on the jumper of the guy in the pic.

    Second pic. One lightsource. One artifact.

    All too much of a coincidence. Its likely dust on the CCD/Cmos of the camera which you can't inspect rather than dust on the lense of the camera that you can.

    That said, go on and post this on a UFO or CT forum and watch the hilarity ensue as they debate this for the next 18 months. :D



    As for Su Campus' pic, That is a rather chaotic arrangement of overhead spots they have in the ceiling of the storehouse isn't it?
