I took my first couple of images at the weekend and when I initially set the timer there was a big flicker of orange light from the camera light (1000d) could it be this?

Don't know what your focuser is like but mine has a gap through to the tube where the flat is for the locking screw. If your camera was positioned differently to previous times maybe it is a reflection of this.

Other than that I haven't got a clue. I blew it up a bit to have a closer look.
