Finally found a short clearing to add a bit more data to what I collected last month.
My main reference was Adam Block's with 28 hours of Ha in a 32"...
Adam Block 32-inch HaLRGB: 28H:8.3H:1.7H:1.7H:1.7H
What you see here is HaLRB: 6.7H:3.7H:1.2H:2H.
Unfortunately the weather turned before I could get G, so I used G = .8B + .2R.
Interesting to note that 6.7 hours of Ha didn't really have much more structure than 3.7 hours of L. I included the Ha for the "starburst" color effect that seems so popular.
