steviemac500 Posted October 14, 2015 Share Posted October 14, 2015 I took some lovely shots of the Orion Nebula last night. The individual shots are lovely but when I go stack them, all the colour disappears. I took around 40 at 30s ISO 800, same darks. Why would this be. I did flats as well and I have tried stretching them in GIMP. I would have expected the picture to have more detail after processing. This is the processed image.

jambouk Posted October 14, 2015 Share Posted October 14, 2015 Nice. What software are you stacking them with? Is there a setting you are missing to tell the software it is a colour image? Why are you stretching flats? James Link to comment Share on other sites More sharing options...
Knight of Clear Skies Posted October 14, 2015 Share Posted October 14, 2015 There is probably more detail and colour hiding in there. DSS often produces very dark, almost monochrome images after stacking. I use the sliders to perform an initial stretch and colour balance and boost the saturation before saving the image.

udaiveer Posted October 14, 2015 Share Posted October 14, 2015 Use the Highlight slider in DSS to taper the histogram curve in DSS.Did you your CR2 (RAW) files? If so try converting all to tiff n then stack. Somehow the results r predictable with tiff ;-)Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
steviemac500 Posted October 14, 2015 Author Share Posted October 14, 2015 Hi, I'm using DSS to stack Sorry, that was badly written, I meant I'm stretching the image not the flats. I haven't tried using the sliders to boost the image before GIMP so ill try that. Is there an option that says its a colour picture? Link to comment Share on other sites More sharing options...
