Combining integrations

@heno Generally speaking it is perfectly OK to load color and mono images in different sessions, indicate when loading them what filter (R, G, B, RGB, Ha, OIII, etc) they are for and integrate them together. In your case, where you have to force CFA on your mono images, you can integrate the color images first, then integrate the mono images and then load the integration results and indicate what filter they are for. No need to load calibration frames but simply go to tab 6 and hit integrate.

One other option is to integrate the mono images first and then the color images with separating the R, G and B channel. Then you can load the integration results for all different filter in tab 9 Combine RGB which gives you more control over how much of which filter is applied to which color. This can be tricky though, depending on the data, so if you are looking for a RGB image then the first option may be easier to perform.

@wvreeven
Thanks for info.
In this case my data are several sessions of color data + one session of Luminance/monochrome. I know I could (maybe should) have combined all the color data in one processing, but I wanted to try the other way around. I processed them separately. So if I add more color data at a later stage, I can just process that and add it to the already existing/processed color sessions. That was my plan at least. 😀 
So I'm curious to the details:
Do I load the integrations as lights? What about other settings like LNC? One of the sessions are clearly off center compared to the others. Anything else I should do before I press Integrate?

I will try your other suggestion as well using combine RGB.

@heno Yes you should load the integrations as lights. Regarding LNC, that really depends on the data. Maybe try first without and then with using the basic settings and see if that improves things. If it does then you can start playing with the parameters. I am afraid that it really is not an exact science, sorry. What do you mean with “clearly off center”? Is the background histogram peak off or are the stars displaced? You may also want to play with MBB to see if you can suppress the borders of the different stacks.

@wvreeven

By off center I mean that in one of the session the plate solving has not worked as it should. The images in that session is shifted some hundred pixels sideways. What I was after was to reduce the effect of overlap in the borderline. I understand that it is MBB that can help me with that.
I'll have a go at this.
Thanks a lot.
