I would try stacking again using different parameters.
There should be much better colour in there.
Sorry I dont have any suggestions as to values to use

Thanks Jennifer, I am following this tutorial here
http://www.stevebb.com/deep_sky_stacker.html The only difference is I selected Sigma-Kappa clipping for the light and dark frames instead of Average. I will have another go at it using Average and see if it will make any difference.
Also, when I save the stacked TIFF file as a 32 Bit Rational file, and converting it to a 16 bit TIFF file in PS, the entire photo was way overexposed and the core was totally blown out. But when I saved the file as a 16 bit TIFF (which is where this photo was made), all the details were preserved. Can anyone explain to me why this is the case?

I hope you don't mind but I had a very quick play. All I have done here is adjusted the colour balance of all three layers, shadows, midtones, and highlights to remove the red and increase the yellow. I then did a slight histogram stretch to bring it out a little further. Hope that helps, keep them coming as I can see a huge improvement in your images, your doing great.

Thanks Rex, I am still learning the finer details of processing as you can see. I appreciate your help, so please keep suggesting on how I can imprve them. A larger file of the same file is here

I will have another go at processing and see if I can remove some of the red and increase the yellow.
