i found one image in the Oiii data set was rotated 180 degrees clockwise so I rotated it counter clockwise 180 degrees before stacking it. In order to get the orange color shown in the data set photo I had to use the Halpha data in both the Red and Grn channel. Also the Sii data was not aligned with the Halpha data.
