Could the orange glow be from a nearby nebula or...

 

Your sunburst orange HHR?

 

Picture from your colonoscopy?

 

DOH! MrMarquis got it on the first guess!

It was a (upper righthand corner) crop from this close-up photo of my fender:




Well, it did KIND OF look like a starfield from some deep space hubble telescope photo. Sort of. To me. lol.

 

i think having the picture named "Constellation HHR" in your pictures kind of gives it away...

 

I just figured that's what an orange glow might come from, 'tis all. Didn't even realize that it may actually be a pic OF your car.
