Have faced a peculiar issue during WBPP Stacking in Pixinsight for two sets of of light frames . Others seem to work fine

I have a OSC ASI 533 MC Pro along with Askar SQA 55 and my recent exposures of M42 and NGC 1499 have generated a black and white result after stacking the frames through WBPP in PI. The same Light frames have stacked correctly in Siril and the result is a proper color image.

I have checked up all the settings in WBPP including CFA and Debayer options in Calibration and Post Calibration tabs and these settings seem to be fine. The same settings give proper result when I stack my Light frames from other objects

Is there something missing . Any suggestions welcome

I think there is a CFA checkbox on the lights tab too, is that checked? Have you tried both setting the bayer pattern to auto, and also setting it to the correct pattern?

Have checked the settings and all the above as you indicated are in place. Not sure what is the issue. Plan to check the Light Frames individually to see if any bad frame is causing this issue. Thanks anyway for the response

Have you had a look through the WBPP log file that is produced at the end of the stacking process? It should state what is happening and if the debayering was attempted or not

Normal WBPP with OSC picture generates 4 selectable outputs : RGB and R, B, G channels . If you end out with only one monochromatic image, it is with a high probability because this image has been the only one selected (you can choose which of the above-mentioned channel are to be created after stacking.

Channel selection is accessible in WBPP parameters, thumbnail “post-calibration”/ channel configuration.

You can check with a small set (4 raw) of images that you actually get the appropriate outputs.
