Very nice Nicola. I was also wondering about the reddish colour. Presumably obscuring dust

Of course you would have had double diffraction spikes but they could have been processed out.

Off topic. No, you won't get double diffraction spikes. The orientation of the spikes in the image depends only on the orientation of your spider not the camera. Just think about the image in the image plane without the camera and suppose star A has a diffraction spike pointing directly to star B. Now bringing in the camera (in whatever orientation) is not going to change this.
