Of course, if I am wrong, then so be it, someone will tell me I am sure. Seems you got the Witch head Nebula near Rigel showing up, although it looks a little B&W like M42 looks, and obviously small at that wide field scale.

Just my noob 2 cents, hope it helps?

Thanks Chris,

My 450D is unmodified.
IC 2118 is not an emission Neb it is a reflection neb, therefore it doesn't emit at Ha wavelengths it is reflecting mainly blue light. This is why I chose this subject to image, it should suit my camera.

Regards
Trevor
