steviemac500 Posted August 19, 2018 Share Posted August 19, 2018 IC1396 - Elephant's Trunk. This is 1200s x 18 each of Ha, Sii and Oiii taken just before I went on holiday. Stacked in PI. Usual background modelisation and cropping then combined channels using Pixel Maths with Sii - Red, Ha - Green and Oiii - Blue. Noise reduction, LHE and then I reduced the starfield with morphological transformation. Colour calibration and finally SCNR. Then over to PS - combined the Ha as a Lum channel then final contrast enhancement. Last stage was adjustment of the magenta stars using a process I discovered today. Hope you like it. https://astrob.in/362254/0/ Link to comment Share on other sites More sharing options...

ampleamp Posted August 19, 2018 Share Posted August 19, 2018 Nice and understated. ? Which method did you use to reduce magenta? I go for simple ? and run with - (1) invert image (2) SCNR/HLVG (3) reinvert image It works most of the time Link to comment Share on other sites More sharing options...

I can send you it if you like? Link to comment Share on other sites More sharing options...

Don't wish to interject with a red-herring but I am aware of this one; I'm afraid I cannot remember where I found it - when I do I'll let you know! remove magenta stars.xpsm It worked for me.
