If there isn't any, then it's something new at the very least! Artifacts or not... [/quote] I'm telling you, I've seen the same thing when processing the images myself as I sometimes do. When it happens I manually change the background subtraction myself to compensate (not always perfectly mind you). Their automated process doesn't even attempt to do that. It's the whole reason I started developing my own technique for processing the images dynamically rather than based on previous images. [/quote] it's not that I don't believe you, i'd just like to see some actual images so I can compare and make up my own mind, that's all :) [/quote] Well seeing as how I tried my best to manually compensate for it at the time I processed it, I'd have to redo all my processing from scratch to show the full effect. I don't have that kind of time today, and I won't have access to my desktop for a week after today. I'm sorry, but you'll just have to take my word for it for now. [/quote] That's ok, maybe someone else can dig up older images to compare. [/quote] Not unless someone else can process the raw BEACON images in a manner similar to what NASA does. I can, but I know of very few here besides me who can do it. Here's an example from a year ago. Now bear in mind I was trying to compensate for the over-darkening and erred on the side of letting some of the frames be too bright and retain a lot of glare. Notice how much the glare fluctuates over time: [youtube]http://www.youtube.com/watch?v=3GfRp38NBj4[/youtube] [/quote]
