Date/Time of photo:

December 24, 2007

Equipment:

Sky-Watcher Evostar-100ED Pro f/9 refractor, Canon EOS 300D at prime-focus. Exposure details: 40 x 1/500 Sec, ISO-200.

Description:

This image has been enhanced to show mineral colouration. Processing details: 40 of the best original frames (from 52 taken) were stacked in Registax 4 to produce a 'luminance' master. In Photoshop 7, each original image was also colour-balanced and saturation levels increased in stages. These processed images were then stacked to produce a 'colour' master. Both masters were then combined in Photoshop to produce the final image.
