An Aurora across the Mersey River in Devonport a few weeks ago.
They are largely processed for the green, which has most of the 'structure', where the red acts more like a colour cast across the image.
Also if you process for the red then the green becomes Lemon Yellow, which you can see in a few of these.
mmm, sorry I missed them Trevor, must pay closer attention, maybe I was away from IISpace for that period
Both post's photo's are from the location too, & why not, its a great posi for the subject !
That's OK Bob, don't expect you to have seen them and that's why I posted the link.
Yeah, I like that site, it's only 5mins drive away and is good for testing to see if it's worth going further afield.
