But we need more StarTools users, StarTools user!
I think my problem with the color module is where it says to click anywhere on the image to white balance. Each time I click, it comes out different. Where SHOULD I be trying to click if not anywhere???

Aha!
Color balancing is performed by finding a good white reference. There are a few ways you can find that white reference.
One way is to click on a part of the image that you think should be white. ST will then adjust the white balance so that that part of the image will turn out white.
The other way is to look at a large part of the image (or the whole image) and reason that, because the universe is roughly white when you add up all energies, then the whole image can act as a white reference. This is what the 'Sample' button does - it samples the current mask and bases a white balance off of those pixels.
If Wipe was succesful, the initial color balance that Color comes up with by default (which is the same as clicking 'Sample') is often spot-on (it was so when I tried your data).
You will be able to tell my the color temperature range of the stars and the color of any features that you know are there (for example a yellowis galaxy core or a purple HII region).
Now I know I'm supposed to click anywhere that is "white"
