[APML] Revised New Tricolor

[Chuck Vaughn <aa6g@aa6g.org>]

Thanks Volker and Marco for your comments on the first image.

I had one night before the smoke moved in to take couple more 
exposures. I took another 90 minute red exposure and averaged it with 
the first one and I retook the blue exposure in response the comments 
about the blue gradient. I flipped the camera body 180 degrees to see 
if that would do anything. There seems to be a little less "blue 
gradient" but the frame is also shifted a little as I didn't get the 
first blue exposure aligned to the red as good as I wanted. The new 
exposure produces a larger field but you can't see quite as far south. 
There's still some drop off in the blue.

I did a lot more work on this image to even out the background. This 
task becomes somewhat subjective after a while though.

Two red exposures does help to reduce the grain a bit.
