P Holdsworth Posted August 3, 2021 Share Posted August 3, 2021 Hi all, here's my image of the Elephant trunk nebula. This is 6.5 hours total integration time of 3 min subs stacked in astro pixel processor and fully processed in pixinsight. Still using a stock dslr and a optolong l enhance filter so overall fairly happy with the way pixinsight has extracted the nebulosity. Have to say I'm loving pixinsight and actually once you get used to the interface I don't think it's anymore difficult than photoshop. Thanks for looking Cheers Paul 9 Quote Link to comment Share on other sites More sharing options...

Pixinsight is just like Photoshop in many respects, half the processes you will never touch. One useful tip I was given, and still use. Save your most used processes as icons on the workspace. It saves a huge amount of time searching for a particular process. You can also rename the icons to whatever you want, as some of the processes as you will know, have very long names. This is my list of icons I load at the beginning of every session. They are arranged in order I use them in the workflow. 2 Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted August 3, 2021 Share Posted August 3, 2021 I have a similar layout as Brian again roughly in the order they are used in my workflow. But some are on the same row so I would use one instead of the other(s) dependant upon what I want to do. Many of the process icons are not used every session but like to keep them available - just in case 😉 They also have any relevant settings embedded within them so I'm not continually resetting parameters. This is what I call my "ultimate set" that will do mono/ OSC/ narrowband etc And this is my "basic" set which is essentially the same as the former but without all the narrowband stuff on the righthand side. 1 Quote Link to comment Share on other sites More sharing options...

P Holdsworth Posted August 3, 2021 Author Share Posted August 3, 2021 Thanks Brian & Terry. Yes I have saved a workspace workflow on the right hand side though at the moment it's quite basic compared to yours. I've only been using pixinsight less than a month but have kind of settled so far on about a 16 stage workflow though I'm probably going to add colour masks from script " utilities" to that. Thanks for the tips & help guys 👍 1 1 Quote Link to comment Share on other sites More sharing options...

What is the Insert_RGB_Stars icon Terry, is it a PixelMath formula? Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted August 3, 2021 Share Posted August 3, 2021 No simpler than that. This is used to extract the Hue component from RGB images and then applying that to narrowband images that sometimes get those weird star colours. Use the Extract _Hue icon on the RGB picture after masking for stars. This does the HSV Channel Extract with these settings It extracts the HSV Hue (H) channel from a RGB tricolor image, maybe from an OSC or Mono Camera with RGB filters, assuming you have taken RGB frames as well as narrowband. Then the Insert_RGB_Stars icon is just this: This replaces the hue of the target image with a specified hue file. To insert RGB stars into narrowband images, select the Hue channel obtained from the RGB image using ChannelExtraction. Then apply to the target image, again using a star mask to limit the changes just to the stars. Obviously replacing <Auto> with the extracted HSV image. Hope this reads clearly 😉 1 Quote Link to comment Share on other sites More sharing options...

Hope this reads clearly 😉 Got my head around it eventually. 😁 I've been using starnet to extract the stars from the RGB stack, then do the same procedure with the NB data, and just replace the NB stars with the RGB stars. I get mixed results with this method, usually blown stars with little colour. Quote Link to comment Share on other sites More sharing options...
