First HDR play

[sinbad40]

Well this was my first attempt at playing with HDR, a mix of 5s, 10s, 30s, 60s and some 120s shots in a very short window last night.  I know the alignment is out due to the number of double stars from the stacking, but this was more of a HDR play, so wasn’t to bothered with that issue at the moment.

I am really happy with the outcome, so once I get chance to get some 180s and 300s shots, I will have a full go at getting this one right.

So i have had another play with HDR and aligned the stars first, but i now have some core stars with dark spots, think this may be down to over doing it with HDR Multiscale transform

You have the "Lightness" and "Lightness mask" options in HDRMT (PixInsight I think you mean?).  If I still find HDRMT too strong, I usually clone the image (drag the image identifier tab to a blank area of the Workspace) and run HDRMT on this.  I'll check a couple of times with changes to layers depending on the data/subject. Then I'll either:

• Blend this into the original with PixelMath e.g. Simple expression:
  0.5*$T + 0.5*<name_of_HDRMT_clone_image> 
  Drag the blue triangle onto the original (where $T comes in, target)
  You can obviously adjust the strength of each blend above.
   
• Create a modified mask that targets the area/areas I want the HDRMT image to replace.  The use PixelMath to replace it e.g.
  <name_of_HDRMT_clone_image> 
  Drag the blue triangle onto the original (where $T comes in, target)
   
• A combination of the above.
