Now I need to combine all the masters (RGB, Ha, OIII and SII). But I’m stil;l struggling with the difference dimensions of the images. How would I solve this so I can combine these images?
Hi Rob, to use the RGB combine (or composite) tool, all images need to have the same dimensions.
Just load the stacks as lights. And register them with Lanczos3 and No under/over shoot. And then save registered frames. Then all registered stacks should have the same image dimensions and the composition used is FULL, so no data is lost of any stack.
I will make a workflow soon for combination of multi channel monochrome data.
Usually, I just make the stacks per channel using FULL composition mode in 6) integrate, without registering the lights to one particular stack, (which you probably created first). It can be done that way, but it’s not necessary.
When you have all stacks, just load them as lights and register them and save the registered frames using Lanczos3 and No under/over shoot.
Let me know if this makes sense and if you can proceed.
