Centaurus A ablaze in NIR.

In terms of pretty pictures Centaurus A isn't much of a subject when imaged in NIR but it is a very different looking object when compared to images in the visible range.
NIR can cut through the obscuring dust revealing a very bright core.

It makes an interesting contrast to the NUV image and was much easier to process.

LRGB L=NIR filter.
3 hrs L, 0.8 hrs G, 0.8 hrs B
BRC-250 scope, ST-X10ME

To show the bright core is no processing fault, I have attached the Two Micron All Sky Survey image from the 1.3 metre scope at Cerro Tololo Chile as a comparison.

I intend to present an animated GIF showing Centaurus A imaged at various wavelengths.
