IC 2944 Nebula with QHY 268 camera

I finally got a couple of clear nights so I was able to capture this nebula as well as the Eta Carina nebula posted separately. 
IC 2944 or the Centuari Nebula. This is a 2.5 hour exposure of a fairly faint emission nebula. 
Note that the stars lack the deep colours as I was using an extreme narrowband filter to defeat the bright city lights and the bright moon. The L-Extreme filter cancels out a lot of the starlight while enhancing the Oxygen and Hydrogen in bright nebula.
