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...
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 ...
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, ...
c) PixMath combine Ha+OIII mixing ((Ha*.05)+(OIII*~.01)) to HOO 0.2 RGB/SHO:(Create Synthetic Luminance with "ImageIntegration" function) a) Run DynamicBackgroundExtraction seperately on SHO, RGB images because combine. b) ChannelCombine to merge RGB into single image ...
Below is the linear file after using PixelMath to combine the R, G, B, Ha and Oiii channels. Nothing done except a little background neutralization and noise reduction. I wasn't happy (able) to get the star colors I wanted. So after the Non-Linear stretch, I used Starnet++ to remov...
ImageIntegration with PixelRejection 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...
increases the signal linearly but because the random noise follows a Gaussian distribution it only increases as a square root function, so the more of them we combine the more we can separate the signal from the noise. For example, if we take the value of the same pixel over multiple frame...
idea of having to use PixelMath for cropping unwanted features (should be an easier way), but finally dove in and found success. Once I got going, I did one more step on cropping — that is I squared the overlapping edges first and then came back and had to nip out only two stars....

I think what it's doing is a median combine of the two images - It goes pixel-by-pixel and performs a median combine on the corresponding pixels in A and B. Since there are only two values in the median operation, I think it devolves into averaging the two, this is typical ...
