Three Galaxies from the Centaurus group

[Ant0nio (Tony)]

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

Lovely images
Centaurus A is a cracker
They must have been captured at low altitudes ?
Well done !

Thanks for the encouraging comments Martin & Tony, it was a last chance attempt before they disappeared over the horizon.
Cheers,

You have captured some great data there Tony. Given those objects were relatively low in the sky makes them even more impressive. Just watch your black clipping, I downloaded your images and had a play with them on my phone's picture editing app. There is so much more detail to extract from your images which has been hidden by your processing. The data is good and holds a lot more than you have shown. Good work all the same and your focus and colour look correct. Regarding monitor calibration, I think PS has monitor adjustments available in colour settings. Your monitor will also have colour profiles to choose from, normally some form of RGB profile will be used. Just make sure it matches the PS profile, if it isn't on the list then I guess you'll have to experiment by choosing the one that gives the best result.

Very nice Tony. As Mickoid says - maybe less black clip, you'll get more out of it

Thank you Mick & Chris for your feedback, & thanks for the heads up re; the colour profile Mick, I'll look into correcting that now.
Regarding the black clipping, my processing technique is just the basic levels & curves with Colour correction/shadows/highlights/smart sharpen/reduce noise to finish.
I guess I must be clipping the black point too much in levels, does that make sense? I'll try some adjustments there.
