Some people have been requesting that I throw this image up online so here it is.

This image is created from 21 pictures and an editing process called image stacking in photoshop.  It is a Quite lengthy posses and took my quite a while.  also it requires a lot of working space.  By the end of the project, photoshop was using 12 gb of my ram and over 100gb of scratch disk space.

What are you looking at.  Well the milky way stars are very dim in the night time sky and since they move over time you are limited how long you can leave your shutter open before the starts begin to form trails. This means in order to brighten them up you have to shoot at a very high ISO.  But ISO brings in a lot of noise and that is no good.  So what pro night time sky shooters do is something called image stacking.  you take a picture of the same patch of sky 20-30 times and bring them into photoshop as a panorama.  it will align the stars since the stars have moved a little.  Here is the nice thing about noise.  It is a constant pastern and the only changing thin in the image after the stars have aligned.  Photoshop knows this and can do a really good job removing the poise without hurting the quality of the image.  also the stacked images can be controlled to brighten areas and control the faint colors.
This isn't the best picture i've ever seen but i feel the next time i try this it will be a lot better.  here you go.
Not the red you see in the corners is a bit of light pollution.
