Hi All
I have started learning to use Pixinsight by working through some of the tutorials online and have followed the workflow process to Star Align the images - each filter done separately. This is my first serious attempt at astrophotography and processing the data.
I have then used the Image Integration process with Drizzle as per the instructions in the tutorial I was using, I then did a Drizzle Integration to integrate the lights for each of the filters, ending up with one integrated file for each of LRGB.
Following the instructions in the tutorial I have attempted to combine the RGB using Channel Combination to combine the RGB. This is where I run into a problem. Whilst the stars are all aligned in the individually integrated lights, when I combine the RGB I end up with them out of alignment. From looking at the combined file it is obvious to me that the Red is an issue and possibly the Green but it might be the Blue. I have attached an example and the individual integrated RGB as an example.
It is supposed to be the Orion Nebula and obviously needs some more work but I cant seem to get the stars aligned when I combine the RGB. I haven't added the Luminence yet as I haven't quite got that far in the processing.
Any suggestions on what I may have done wrong or missed doing would be appreciated.
