Nice shot jp.

I'm again struck by how symmetric the halo appears to be. Through my 8" it looked nearly perfectly round with a tiny bit of extention that I attributed more to reflection in the eyepiece than any natural extention.

This seems rather odd to me. Outgassings wouldn't be so symmetric from what I understand. Sure they can redistribute themselves, but that much this quickly?! The same for some sort of collision. Makes me wonder...

Seeing your images that confirm that nice symmetric halo only confuses me more.
