Nova Sgr 2009 No3 and first light for my new camera

I have taken a few images of this nova now. The pic below is taken with my new ST10EME through B,V,R and I filters on 19th August.
I allocated the photometry filters as colour image filters and combined them as a colour image. The individual frames are B and V 3x60 secs
R and I 3x 20 secs. The I filter isn't used in the colour image.
The nova is clearly quite red and has a very close companion that is also very red.
So this is essentially the "first light" for my new camera.
I haven't bothered to get rid of all the random hot pixels in this image but did the usual dark subtract, flat etc.
Image size is 26 x 40 arcmin. South is up.
