NGC 5128 in various wavelengths

As promised here is a animated image of NGC 5128 imaged in near UV, visble and near IR.

The wavelength ranges in the captions are based on the luminance filter transmission data.

Unfortunately animated GIF files don't do the resolution of the image much justice.
The animation can be found here.

If your browser (Firefox etc) supports it a better quality animated png can be found here.

Finally a near UV/visible image of NGC 5128 in 100% resolution is here.

The imaging details are:
LRG(UV) IMAGE L= (0.8 hrs B+ 10 hrs UV), 0.8 hrs R, 0.8 hrs G, 10 hrs UV
LRGB 1.5 hr L, 0.8 hrs R, 0.8 hrs G, 0.8 hrs B, ST-10XME. BRC-250

I'm quite pleased with this image as the OB associations are very conspicuous due to the near UV data.
Also the high contrast of the near UV image made it a very effective "pseudo high pass filter" when combined to the visible image.

This image is also found in the attachment.
