If the image filter is enabled, calibration and alignment only results in R G B addition. This results in 1 result file. The result should be three aligned frames.If the image filter is disabled, you get three frames, but the first frame is added in the second and third frames.
I will check the calibration & alignment for colour images. I assume it will work for mono images so if you process (calibration & alignment) the images as if they are mono it will work.
The question you could ask what is what calibration & alignment should do with seperate colour images.
Cheers, Han
Calibration and alignment should not depend on the separation of color images. Check out the second problem when you turn off the separation color images. It is added from the best frame to the rest.
I have just set it up with some images. I see some problems with detection of the flat filters and there is no CALSTAT keyword and in some cases no record of the number of flats and darks used. I will fix that first.
In your setup do your have different flats for each filter?
It goes wrong if you have classify "image filter" checked. Only the "flat filter" should be check marked. The calibrate & aligned files are written but then is continues wrongly with stacking. The last stack files can be deleted. I will fix that today.
It should be fixed in development version 0.9.416. Uploaded for Windows and Linux. Try it and tell me if it works. For download Windows version use this link:

When you align three images, the first image is added to the second and third images. Can make a separate function only alignment without calibration?
You can place the images in the blink tab and there is a button "export aligned".
But I don´t understand your current problem. Are your sure there is not an light accidently in the darks tab or flat tab?
I have three images R, G and B. They are already calibrated and do not require flat and dark. I want to align them.
Two possiblities:
1) Remove darks from tab darks, remove flats from tab flats. Load them in tab images and select option calibrate and alignment. The files will be aligned and and new files will be created name ending with _aligned,
2) Load them in the blink tab. Check mark align and use button "export aligned" The files will be aligned and new files will be created name ending with _aligned.
If that doesn´t work for you, give me three of your files for testing.

Thank you, I used the second method.
I will test it today with colour images. Users normally use seperate colours or mono images.
I checked today with colour images. Method 1 worked normal. Did you check for images in the dark and flat tab? Maybe I miss something. A copy of log would also help. Any unforeseen stacking would be reported in the log.
Cheers, Han
In the first method, I aligned the already calibrated frames and did not use dark with flats again.
