The LRGB "stealing" was just a tutorial to show how LRGB works :) .
In the image the blu channel is very weak, I think that it can be boosted during the trichromy since your image is still noise free.
25 minutes for R, G and B may not be optimal as S/N ratio, this is why I suggested to post the separate channels. Depending the sensitivity of your CCD and the filters, something like 20 / 25 / 30 may be better.

thank you so much..I will work on it. I will actually be posting an effort with RGB and M13 on this same string. I am working on it tonight and took it after doing the best job I could on attaining estimates with the white star test. I did not get highly consistent results, but will post results soon and hope someone will be willing to critique it. thank you again.

Here is M13 with RGB and ratios of 1/1.3/2.0. Processed in AA from there. 8"Edge/Atik One 9.0@f10. 55 sec R,90 sec G, 120 sec B. Trying to learn how to get good color. It is very difficult for me to manipulate color. This image is after a lot of filters and tweeks. These are 20 subs/15 darks. Anyone who can help me get good color? thx

Couldn't decide which one I thought was better.

The white balance coefficients in Trichromy (you used 1.0 / 1.3 / 2.0) are not so important: after the creation of the color image is mandatory anyway to use the Color Curves Window for a good result. To guide yourself Google - Images: " m13 cluster " and compare with other images.

You may also increase the Saturation and darken the black background. A further bit white saturation of the nucleus is possible.
The image seems to me pretty good yet, for a 5 minutes exposure.

Excellent result!
For publication/printing it's perfect as it is.
For a more "scientific" appearance, you may leave some sky background (with its noise) instead of cutting it to a constant value.
