Image info

Telescope:  Skywatcher 8" f/5 Newtonian

Focus:  Prime focus

Camera:  SAC7B, uncooled

Exposure:  76 x 25s 

Date:  10th March 2003

Processing:  Acquired in K3CCDTools as AVI.  Stacked in Iris.  YRGB image, composited in Photoshop.  Colour enhanced using Multiple Luminance Layering.


Processed using the YRGB technique, my first image using this technique.   Banding noise was quite strong in this image so I used wavelet processing on the luminosity image.  In retrospect too much was applied resulting in a very soft image.

I was quite pleased, though that the colour of the centres of the galaxies came through.  The galaxy shapes are so peculiar that without colour, it was not apparent where the cores were.
