Hi Ray76, ..note: Apologies for larger size pics. Zoom necessary. Here are image sequences that show this phenomenon. Keep in mind that the "seconds" in the lower image can be steps of approx 250milliseconds. This means there are multiple images between the second marks. IT takes great care & the right setup & tricks on your system to access these frames (fullscreen mode, precision control of advance bar - few pixels at a time, etc).
For brevity, I've captured relevant sequences. Otherwise it is too much information to post (too many images). Hopefully these sets of sequences will illuminate the discussion. (i.e. can reflections cause these dynamic results, is this debris, are these waves, etc).
I have an advantage on my high end workstation as I can see more detail than what I can post. So I don't mind if conclusions do not concur. (I do image analysis of deep space infrared telescope pics with this system).
To help on the lower resolution viewing, I shifted the color parameters on the last image to help make it easier to see. In this color shift, ANY reflection source would stand out. Thus the reconciliation with the shape to a suggested reflection source would be the key to answering (for the "reflection" thesis).
Another interesting point about "reflection" or "debris" is that it has to fit within the "comes then goes" in addition to the "faint to bright" dynamics.
I'm including the rest of the cc's so they can give feedback on how these images look on their systems - & to keep them up to date past "bubbles" discussion/post many many threads ago.
