Also, when I look at the daytime picture, I see another branch that is not visible in the picture with the phenomenon. If the object was behind the tree, that other branch will be seen crossing the light. I also agree that the object appears to be in front of the visible branch.
Given this, I have a theory. There is a seal that is supposed to go around the LED array sealing it to the Lexan covering so all the light exits there on my Orion's. I'm presuming these are X-series images and I'm not as familiar with them. On my older Orion cameras, sometimes this foam seal comes loose. I haven't noticed any real picture issues so I've ignored it.
If somehow, some light from the LED array is entering the lens area and exiting through the Lexan covering the lens, then a droplet of water on the Lexan could reflect light back into the lens. Since it is so close to the lens compared to the rest of the objects, even a little light reflected could look bright.
I'm not sure this is it, but I think it could be possible.
Thanks,
Jack
