contouring star density

[aworonow]

I'm interested in examining obscuration of distant stars by bright and dark nebulae. Is there some mechanism within PixInsight that would, even roughly, allow me to contour (or annotate) spatial variations of star abundance within an image?

Thanks, Alex

You might try this: open a calibrated image, run FWHMEccentricity script, select the view, click Measure, click Support, and click Save As. You will get a map of detected stars and a text file of their positions and shape statistics. Maybe post process this point cloud to get contours?

Mike,
  Yes, I think you've got it! A little coding around the text file and I should be able to extract what I need.

Much Thanks,
Alex
