I
think the best method is with the use of a diffusion filter
(like those by Alson Wong, Bill & Sally Fletcher). Seems to
retain the color of the brighter stars much better.
However, you can simulate the effect to some degree in
Photoshop:

I too
have taken a few shots of this area (using RG400) with results very similar to
yours posted. I like your wide angle shot as it shows a great deal of the emu.
But a
question for the list:
Because the milky way is so rich in this part of the
sky, it tends to over-dominate the stars of the cross and the pointers. What I
would like to do is to achieve an effect similar to Akira Fujii's image of the
cross and the pointers where those stars are easily distinguished but the
background milky way is still rich and detailed.
Are
there any suggestions on how to achieve this in processing the images.
Naturally, shorter exposures skimp on the detail in the milky way and show the
cross and pointers with a bit more contrast, but as I am yet to try stacking any
images would I be able to get the effect I desire by stacking a short and long
exposure together? Or are there any other processing 'tricks' that may help
achieve this?
Craig.
