The HDR strategy is working well! Nice one Micke.

I had a try at the 120 second stack last night but got over enthusiastic with the saturation tool and ruined it!

Perhaps I'll have another go tonight.

Your blue has come out well Ruud.

Is Topaz a standalone or part of Photoshop?

Hi Graeme,

Topaz makes plugins for photoshop, but you can use them in GIMP as well. I've been using Adjust mainly to enhance details in clouds: it makes them look dramatic. Adjust is a tone mapping plugin that increases local brightness and colour contrast independently. You can adjust the strength and radius of the effect. Check out Topaz Labs on YouTube.

Do you use the G'MIC plugin collection for GIMP? G'MIC has a very good tone mapping plugin. Works very well for luminosity and you can set it to work on individual channels too, which may help bring out colour contrast. I must try it myself.

Greetz to you and David and thanks for a fine challenge!

Thanks for the excellent M31 data David (@Jockinireland). Interesting to see the differences between the two exposures and between everyone's processing methods.

Moving on to AP Processing Challenge No.13, Gordon has submitted his APOD award winning IC5146, Cocoon Nebula image files for us to have a go at processing:
