Narrowband Imaging the Crescent Nebula

Received my Hydrogen Alpha filter yesterday and we got lucky and had a couple hours of reasonably clear sky.  Although I didnt get as many exposures as I'd liked, my first real attempt at narrowband imaging was a success.  I imaged 2 objects - the Ring Nebula (M57) and NGC 6888, the Crescent Nebula in Cygnus.  The Ha frames that I took of the ring were washed out possibly due to clouds, but the Crescent came out just fine.  

I have never before gotten this much detail on this object before.  In the past, I was able to capture the bright outline with a tiny amount of  the inner nebula.

The above image consists of only 25 minutes of H Alpha and 25 minutes of O3.  Ha was mapped to red, Oiii mapped to green and blue.  I used the Ha stack as the luminance.  This was done with my light polluted backyard, and the Oiii was taken during the last full, supermoon.
