Hello all. I have a question about my background, as you can see from the image I have a really bad magenta color cast, and I don't know how to fix this. I tried with some plug-ins to remove the gradience and flatten the background but I end up with a very unnatural looking image so I avoid them. The image is stacked in Deep Sky Stacker. Camera is Canon 600D/T3i modified 42x300sec UHC filter 30x Dark frames 50x Flat frames 50x Bias frames I'm processing images with photoshop, so I would really appreciate any suggestions or is anyone knows what am I doing wrong. Thanks in advanced.
Haha...just kidding. It was a ruse to drag you in here :). But I do have a question that I can't seem to articulate enough for Google search engine to give me a useful answer. It is with regards to the big bang theory. As I have understood it, the entire universe was once compressed into a singularity. All the matter in today's universe was once there. This singularity 'exploded' and the whole universe came into existence. In my mind, I am picturing a grenade that explodes in mid-air, and all the fragments disperse away from the center. This fits nicely with the observation that all solar systems and galaxies are traveling away from each other (you know, the balloon analogy). I've often heard it said, that if we had a telescope powerful enough, we could look back to the big bang. But if that light is 12.7 billion years old and we can see it, then how the heck did we get 'out here' to be able to observe our own creation? It would be like yelling 'hey', run 2 kilometers away and then hear yourself yelling 'hey' from where you came. This is theoretically possible. If you can run faster than the speed of sound. But since we cannot move faster than the speed of light, how can we see anything from the big bang? Am I even making any sense?
