Astro's explanation:refraction spike. The first pic has refraction spikes, this look like something a bit different to me.
Quoting: Seer777 Wrong. The correct term is DIFFRACTION spike, not refraction spike. Furthermore, the reason it changes mid-stream is because of a seam in the stitched mosaic. I already explained all this before: [ link to www.godlikeproductions.com] Top of one film plate: [ link to archive.stsci.edu] Bottom of the other that they stitched it with: [ link to archive.stsci.edu] When you stitch those two together, this is what you get: [ link to i319.photobucket.com] The diffraction spike is different in the two because Sirius is at a completely different position relative to the optical axis in each image; in one, it's in the image, in the other it's off-image and above the telescope's field of view. This is what you get for using a secondary source of information rather than the raw individual film plates from which the mosaic was derived. In other words, sloppy research technique. /debunked Why the fuck would you stitch those two together? And why is nothing else out of frame? Dude, the image at the bottom of the film plate is just that, it's at the bottom of the film plate. The image at the top of the film plate is the start of that film plate, not the end. It covers much more of the sky below it, but they stitched it in about that spot where there was overlap for their software to match up the stars and stitch the plate images together. You say they, but I thought you said before that it's an automatic thing when Sirius glare is too bright. Still doesn't explain why there's only a spike in the overlap.
