Today I noticed a large ring (perfectly circular) that circled around the sun, although it was clearly not part of the sun, and it had an orange-ish tint to it. Does anyone know what this is. Wondering if it would be possible to implement into a daylight equation or something similar.

Best guess, reflections/refractions of the atmosphere. Just a guess though. Too tired to research it.

Yep, apparently and it has a name the "22(deg) circle".

Yes, this is true

, sometimes I wished I didn''t think like that, and at other times I don''t.

There are a lot of things I would like to try and implement, with sooo little time to do it in.
