I have been noticing recently that all the time I put in initially with PCC or traditional color calibration is sometimes lost after I use the LRGBCombination process.  Not completely sure what is going on here besides the Lum highlighting different areas of the image that are a bit more bias in one color? 

What is the best way to fix the problem?  You can manually use HistrogramTransformation to fix the problem or in some cases export to photoshop and then use autotone or autocolor.  However, it seems like there should be a better solution.

You have to manually add them back.  See the post a couple threads below this one.  This really is a PITA.  Love the new features but getting a good SHO script should be a top priority.

Glad to see progress for Pixinsight.  Out of curiosity at CEDIC a couple years ago you announced a replacement for DBE but it seems that it has never been released?  What is the status of that project?

Bad data is always going to be bad data.  I already feel like we see too many attempts to fix or shrink stars created by hardware/seeing issues.  Its a bit disingenuous to pass off photoshop corrected stars as reflective of the abilities of your system. The original image is reasonable for the equipment you have so I would post that.

Bug Reports / ImageSolver Problem
« on: 2018 December 04 23:53:52 »
I'm trying to use my image with Aladin but when I plate solve with ImageSolver the star coordinates appear ever so slightly off so Aladin draws boxes in the wrong position.  When I plate solve using TSX it works perfectly.  All images were captured with TSX.  Interestingly the annotateimage script in Pixinsight annotates the ImageSolver image correctly

It looks like it’s finallt available?

Did this get published?

It looks like Vicent stopped doing classes and the documentation for sale effort.  Would still be interested in seeing the workflows from the classes available for purchase.

I played with that script a bit and looked at the PowerPoint here. .  It seems to work fairly well but produces a noiser image and the color tends to be a bit hot pink compared to the RGB frames but maybe better than Salmon?

I was noticing that myself today.  It seems like the HaRVB-AIP script does a better job here

Yep that fixed it!  Thanks

I haven't used PixInsight in awhile to do stacking but I had a particularly bad framing issue occur that CCDStack couldn't register.  In any case I've run into an issue where imagecalibration would take my master flat (already calibrated with flat darks) and overcorrect my light frames.  The light frames now have white dust moles and a dark center but are bright towards the edges.  Using the same master flat frame in CCDStack and Nebulosity calibrates the light frame correctly.  I did make sure PixInsight had calibrate unchecked on the master flat.

Unfortunately that is correct.  The NBRGBCombination script uses a different method.  I have actually been having great luck using image integration to do a noise weighted integration into both R and L.

General / ImageIntegration on Two Images
« on: 2017 October 23 21:28:53 »
I was curious why ImageIntegration doesn't allow you to do a noise weighted integration of only two images.  I have a situation where I'm shooting SH2 187 and I want to use some ha frames I took to enhance Lum because neither stands on its own.  I could use PixelMath but I would like to use a noise evaluation based weight but unfortunately it appears that the imageintegration process requires at least 3 images.

It needs a few update so I was wondering if progress was made on the quote below:

Hi Folks
I spoke with Laurent.
We will try to update the AIP scripts in the next 2 weeks ( maybe counted in PI time unit    )[size=78%] [/size]
