Reflections

I have been having issues with reflections in my images that I need to track the cause of. Some turn out just fine while others are almost useless. I have these both when I added a flattener lens as well as afterward. There is a difference in these images as it seems. Some have arches that change position and shape in time. Previous page showing images taken with the lens in place is here http://www.astral-imaging.com/reflection.html
