RE: NASA’s Webb Reaches Alignment Milestone, Optics Working Successfully
It's interesting that they have a special, "selfie" mode for diagnostics and configuration.
More on this from @sarahjay1, in her article, The James Webb telescope completes its optical system fine-tuning and sends an stunning photo of the Universe, and here's an embedded YouTube video from the NASA link (the thumbnail is a 'selfie').
I'm normally skeptical when a government official says that something is performing better than spec, but hopefully it's true this time. Looking forward to seeing images from the earliest times in the universe.
I zoomed in, and saw a number of what looks like digital processing artifacts in the image. I asked a question about it on a Reddit post for a YouTube video, but I haven't gotten feedback yet. If those artifacts are from processing, uploading, me downloading it...
Based on a reaction video I watched from somebody who apparently follows the NASA team closely, along with a community of people who interact via Discord, the team was genuinely surprised and happy about the quality. I think you're in sound territory to hope it's true.
I love the selfie idea too! Really cool to see the 18 pieces of the mirror aligned so well.
