I tried this beautiful nebula 2 years ago and very much wanted to have a 2nd chance, especially after viewing Adam Block's very high resolution image. While I have not succeeded in getting what he did from a much larger aperture it certainly is hopefully a better effort than my first.
As usual I imaged simultaneously with both TEC refractors. I took a lot of Ha data but didn't end up using too much....mostly just a bit for the dust clouds across the bottom of the frame.
TEC180 G2-8300 Luminance 56 x 240 sec = 3.73 hours (Astronomik CLS)
Ha 34 x 480 sec = 4.5 hours
TEC140 Trius R 53 x 4 min = 3.53 hours
G 43 x 4 min = 2.86 hours
B 45 x 4 min = 3.0 hours
Optec FocusLock Used for all subs.

Thanks for looking!
