OP, who seem like an accomplished astrophotographer is sharing a proud moment involving his work. All you can say is how bad the movie is? You can share this in on a post about the movie itself. Btw beautiful photographs OP.
This is supposed to be a smart community..but you and at least at 30% here dont seem to be able to grasp, the OP is not the Astrophotographer.
Its seems the post is part of a coordinated pump on the movie here by Amazon Studios. As you can see, if you look at the amount of related post coordinated with the release. And never seen for any other movie...
I don't see any reason to suggest the HN submitter is the same as the article author, especially considering the high volume of submitted articles by the submitter.
