I assumed that would be the case, figured it would follow the same concept line as tracking Ha and OIII, sometimes leaves some funky artefacts.
Ultimately I do still believe that per sub dynamic range is important as there are quite a few regions where there is a large dynamic range. Stacking a lot of subs may increase the dynamic range overall BUT you can only work with what each sub provides. This is fine when you have either bright or faint regions but it doesn't work with both ends of the spectrum.
This is one reason the 16803 is still king for wide fields, it can capture both faint and bright areas in a large FOV.
