Re: [APML] Southern Cross and Wide feild Milky Way

Hi Craig:

I have fiddled with this sort of thing without achieving anything noteworthy (other than experience <G>) but the way I approached it was to take the shorter exposure image (brighter stars only) and blur it a bit in photoshop, then combine it with the sharper, longer exposure image. It worked (though not as well as Fujii's stuff!).

Monte,

 

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.
