Thank you for the clear (qualitative and quantitative) explanation!

Hi phyzguy, Thanks! Now I see, but why internal reflections are produced in the case of bright stars? Is also possible having ghosts in the case of other bright sources like quasars?

Very clear, thank you! :)

Thanks! The image is from the Digitized Sky Survey, a ground-based imaging survey of the entire sky, performed with Palomar and UK Schmidt telescopes, producing photographic plates that were later digitized.

Hi all! I am new here :) I was observing Orion with the astro software Aladin and I found two similar relatively weird objects. I would like to share with you the image, with the zoom on each of them. Any explanation? Could they be the same object (a satellite?) seen in two different moments...
