I do struggle with the vignetting on this set up, but I am normally able to create an image form the data. In this case, I used 10 lums, 22 reds, 10 greens and 18 blues all at 600s. I also combined this with 24 lums, 24 reds, 12 greens and 18 blues all at 300s. All in all this totals 16.5 hours imaging time. Take care everyone. Simon
