I mistakenly took 4 hours of data with my Optolong L-Quad filter instead of using my L-Ultimate filter. Is there any way to integrate that data into my L Ultimate data in PixInsight or should I just trash the evening? I really need the integration time on this object which is only available for a short time where I am. Thanks.

What is the target that you are imaging?
extract ha and oiii from L Ultimate data, and add them into L-quad data.
Yes, there is. There's a plugin for PI that's called DBEXtract. It is used mainly to combine stacked unstretched subs taken with an OSC, using an Ha-Oiii fllter and an Sii-Oiii filter, to simulate SHO taken with a mono camera and three filters (S, H and O). Try it and see if it produces the results you want.
There's also another method. After making an integrated unstretched image with your L-Quad filter, you can combine it with an integrated unstretched master taken with the-Ultimate filter, using the standard PI image integration process BUT--the image integration process requires at least 3 images, so make a copy of either integrated image (in your case the Ultimate or the Quad) and give it a different name. Then you can integrate the 3 images into a single integrated unstretched master, using the data from both filters.
There's a third way that involves channel separation of the Quad and Ultimate integrated images and then combining the channels into a new RGB image. I've never used channel separation in that way so I can't say much about it. Others will know more about that method.

Crescent Nebula raw data available for processing - 21 hours collected
Hello all, The time has come again to offer up some of my raw image data for anyone to process if you’re up for it, specifically my 2025 acquisition of the Crescent Nebula in Cygnus. I captured this in a relatively narrow FOV with my Celestron C6 sco...
