The Rosette Nebula in Ha, 3x3 mosaic

Hello

I took this image at home during several nights, it's a 3x3 mosaic of the well known Rosette nebula.
I am now working on the OIII filter, but don't know if will have enough clear nights before it disappears behind the buildings i have on the western horizon.
