Chris joins Leo to talk about how Elon Musk's Starlink satellites are causing problems for astral photographers and astronomers. The satellites are congesting the night sky, even though SpaceX says that they are putting sunshades on the satellites to prevent light reflection and make the satellites more invisible. But Chris says that instead, they are reflecting infrared, which is also problematic when scanning the sky and taking long-exposure photographs. Chris says at least SpaceX is listening and is trying to engineer a solution to prevent light noise from reflecting down from the sky. What they are learning is that astronomers use "stacking" to take multiple photos and telescopes use CCD sensors to image the night sky.  If overexposed by light noise, it can affect more than just the area the satellite is in. It can blow out entire rows of pixels. So SpaceX is working to solve that by rotating the satellites so that the solar arrays aren't visible. So it's a multiple approach.

Our next photo assignment is - OUTSIDE. Take a photo of, about, or otherwise concerning the concept of "OUTSIDE" and then post it to the Tech Guy Group on Flickr. Make sure to tag it with the word "TGOUTSIDE" as well! And if Chris likes it, it could end up on next month's photo contest review segment!
