Description

The color mapping is based on Principal Component Analysis transformation. 

Experimental background modeling by 2D-spline optimization.

Even with this integration time, nearly 100 hours, I had a hard time with this one as sky background noise (due to light pollution leaking through these not-so-narrowband filters) was quite unforgiving after subtraction. 

South is up (yeah, the "Lion" is upside down, sorry I prefer this orientation)
