Astrobdlbug Posted February 11, 2021 Share Posted February 11, 2021 lots of reat detail in your image and the dust lanes are wonderful. Did you use deconv on the lum ? Its always tricky balancing the amount of deconv and the ringing esepcially with such a huge amount of nebula in the background. Im sure you've been through the options to try and get control over the dark halos. I offer up a couple of ideas - use starnet++ on this final image and clean up the 'holes' on the starless image with clone stamp or equivelent and then add the stars back in - with possibly a slight gussian blur on the star layer as explained below Second option is very much a PS fix - make a layer copy and slightly blur the top copy <1 and apply a mask all to that layer then using a white paint brush sized to match the star + halo click on the stars affected and blend with 'lighten' - appreciate this is very much a conmetic fix - but its so worth it to just move the image into another league Another technique I apply to star layer when the whole image has been processed through a deconvolution and sharpen is actually to apply a tiny blur about 0.2-0.4 as that take away that 'edgy' appearance and makes the whole image look more natural when th estars a blended back in. Its still a stunning rendition of Orion but IMHO the dark halos need a bit more work -hope you are ok with the feedback Bryan Quote Link to comment Share on other sites More sharing options...

I never use deconvolution - for two reasons - firstly I have never managed to get a result that I am happy with - it always seems to make the image dull and flat. Secondly its the one process that to me identifies it as processed in Pixinsight! I still have work to do on the stars - its something i always struggle with and I will try your very helpful suggestions. Thanks again. Watch this space!!!

AstronomyUkraine Posted February 12, 2021 Share Posted February 12, 2021 Excellent image, love the detail. As for the star halos, I found using starnet just after stretching, (not forgetting to create the starmask for reintegrating stars later in the process), works fine. The residue left by the halo can be erased using the clone stamp tool. I have never had good results from using deconvolution either, I much prefer to use Morphological Transformation when dealing with stars, using the Erosion (minimum) operator.

MartinS Posted February 13, 2021 Share Posted February 13, 2021 What a transformation, the stars no longer detract from the Nebulosity, wonderful. May I enquire what process was used to tame the stars. Quote Link to comment Share on other sites More sharing options...

May I enquire what process was used to tame the stars. I used starnet++ to remove all the stars and create a star mask. Then in Photoshop repaired all the holes left by the star haloes using clone stamp (very time consuming) - then processed the stars to make them tighter and brighter then blended the two images back together. 3 Quote Link to comment Share on other sites More sharing options...

Thanks Gina - it was a bit of an experiment really before the target disappears from view for the season. 1 Quote Link to comment Share on other sites More sharing options...
