CombineImages: Combines two images using PixelMath, but without the need to understand PixelMath. Even for those comfortable with PixelMath this script might be a time safer. And you will see your combined image result as a preview. ImproveBrilliance: You should create some previews of some r...
That expression is the one to use to generate the stars-only image from the original and starless images. To re-screen the stars back onto the (perhaps further processed) starless image, it is:~((~starless)*(~stars))or, since op_screen() has been added to PixelMath:combine(starless, ...
This is the part where you need your images to be stretched. If you still want to combine your channels in the linear phase, you will need to work with stretched copies from now on. I’ll start with an example of a dynamic factor I’ve made for a custom bicolor combination :The ...
2) Next year, what you'd want to is to create a second set of Calibrated images, combine the two folders of Calibrated images and then register and stack everything all together. Plus you want all of the files you are going to stack to be measured against each other to get ...
Generally due to the varying conditions of the night sky throughout a night of imaging, or various nights of imaging, as well as the filter being used, the average brightness of the background and signal may not match up well between images we need to color-combine. This is above and ...
The next thing we need to do is match the intensities of the two images so that GradientMergeMosaic (GMM) can do a better job at merging the panels. Normally I would use the LinearFit process for this, but it has one big issue. When it adjusts the image it can raise the background...
We should now have a bunch of calibrated flat frames that we need to combine into a master flat. Bring the ImageIntegration tool back up and select all your calibrated flat frames. We are going to use very different settings from what we used for the dark and bias master frames. First,...
TheImageIntegrationprocess will combine all your aligned light frames into one stacked image. There are many settings you can tweak, but for now you can use the default settings. Just make sure you use Pixel Rejection and pick a rejection algorithm to get rid of your hot pixels and some of...

For what its worth, I apply SXT to the linear image right after PCC and re-combine the two processed, stretched images right at the end of my workflow. That's more or less what I proposed. The blend addresses the saturation issue I mentioned. W wlickteig Member Jul 5, 2022 #11 ...
