This is a series of screen shots of the results I get when I try to use the tool to remove vignetting.  I get basically the same result regardless of the integration.   Any ideas of where things are going wrong would be appreciated.

Thanks

Chris

I had already reviewed that tutorial and believe I am following the guidelines.  This is an RBG image from a Sony CMOS.  I have darks but no flats.  Light pollution tool and star calibration tool work fine.  I have tried all three of the models, and while the two KangWeiss are a bit better, I am still left with an unusable image, regardless of stretch.  Is is important to stretch it out to the extreme before using the tool? Am I oversampling with that many green boxes?   I also watched the video tutorial and can't see anything that I am doing differently

Thanks.... Not the end of the world, but it would be nice to have it work

The vignetting tool is not so effective. Much better to go directly to the light pollution removal tool, which is takes care of gradients and vignetting and background neutralization in one go.
