DescriptionThis 3D image was a result of numerous tests of both exposure times and timing between images in order to produce the best overall effect. If you allow your eyes to relax and focus to infinity (as if daydreaming) you should see 3 images of the nucleus, concentrate on the center image until it snaps into place and you should experience the 3D effect. The pay off is the “multiple” structure lines in the outer coma that would perhaps otherwise go unnoticed. Each image is a composite of both 1sec and 8sec data.
