Three Galaxies from the Centaurus group

It surprised me to learn there are 30+ Galaxies in the Centaurus group, seven of them considered to be "large". Here are the three best known of that group, Centaurus A, NGC 4945 & M 83. Capture details for each are;
Cent A ~ 19 x 600 sec exp, North Group 127 ED triplet @F 7.5, SBIG 83000C
NGC 4945 ~ 20 X 600 sec exp, William Optics FLT98 @F6.3, SBIG 83000C
M 83 ~ 19 x 600 sec exp, North Group 127 ED triplet @F 7.5, SBIG 83000C
All acquired & stacked using Nebulosity IV, post processing in Photoshop CS2, Guiding with PHD.
Whenever I save the final image from Photoshop, they always end up vastly different when displayed on my monitor (which is calibrated correctly).
Anyone know how to match the colour profile to your monitor & is there a certain profile best for AP?
Comments Welcome & thanks for looking.
Cheers,
Tony
