I am surprised it turned out this well. Its really a dark site target.

Thanks Greg!! Your proposal is the way I am imaging. The Hutec IDAS is actually mounted in front of all the filters. Even so, I do get some gradient in R and G...probably just LP from non Sodium or Mercury source. PS I saw your older image of NGC6744 from a few years back. Wow that was DEEP. I thought I should just give up!!
