The page is there it just isn't connecting through SGL. Copy the link into your web browser. but make sure the URL contains /astrophoto/ in place of the /ast.../.

Its definately there, how do you think I found it.

The link links directly to a pdf - if your browser isn't configured to deal with them it'll appear to be a dead link.

You need Adobe Reader on your computer or you won't be able to read the file.

As a starter, try this:-

From PhotoShop, select Layer - New Adjustment Level - Levels and you will note the default histogram is that of ‘RGB’. Using the drop down list box, choose the RED channel. You will immediately note a change to the histogram display. Ensure that the ‘preview’ option is selected so that you can see the changes that you are making to the appearance of the image in real-time. Slide the left hand ‘slider’ to the right until it is lined up with the start of the steep ‘slope’ of the histogram - it is important not to go past this point or you will be clipping your data. You will note that the image has changed its hue to a greenish tinge. Now, repeat the process for the green channel, noting that the hue has now got a blue tinge to it. Finally, repeat the process for the blue channel and you will be rewarded with a much better background sky colour and a far better colour balanced image.
