Hi Aaron,
A really nice image there, more so in your second processing attempt. If I can give you a tip when processing with this filter ? I used an STC Duo which is essentially the same sort of filter. Processing the image combined is very difficult to do to achieve natural balance. I spent a long time struggling with it. Then I found a separate channel processing tutorial on Astrobackyard on YouTube. If you are using photoshop like me, I haven’t found a better technique yet. Give it a go and let me know what you think. You’ve got some really nice data there to work with so congratulations and well done.
