Do you bin the camera 2x2 or even 3x3 to speed up the process? It doesn't look like it has a lot of detail in the UV so no point in not using binned?

Greg.

Greg,

Since my original intention was to use the UV images for luminance they are unbinned as I would never sacrifice resolution on luminance images.

Hello Bob,

Since the UV data has been mapped to the Blue channel, hot stars emit more UV light than cooler stars hence the hotter the star the more blue it appears. Conversely the cooler the star the more yellow it appears in the image. If you look at the high resolution images for the visible light and UV images you will also notice that for the foreground stars, the redder the star in the visible light image, the yellower it appears in the UV image.
In effect the image is showing the blackbody radiation effect of temperature versus colour.
The exception is the red region at the centre of galaxy which is caused by the scattering of light by dust rather than blackbody radiation.

Incidentally that is a fine Centaurus image you have produced.

Regards

Steven
