If you have an explanation, please post it. Thank you!Enclosed I send you a link of a very strange refraction effect over a glacier in the french Alps (Mont-Blanc-Massive):
First I pointed the sun with my GOTO mount before the sun appeared over the summit.
I was surprised when I saw a wonderful diamond ring effect at the wrong position; 1° left from the calculated point.
But what's that! The sun was slowly going down and disapeared behind the glacier. A sunset before sunrise?!
I hope to find a correct answer for this effect.
