Horsehead, flame, dust and.. a strange star

At the bottom right you can see a strange star with spikes, unusual for a refractor
Here a link at a CROP of a raw file.
The spikes are similar to those of a bathinov mask, they appear in all the raw and in one star only. I can't understand..

I love the detail, colour and contrast.

I am still suspecting that it might have to do with Alnitak. In my attempt, there was a strange reflection approx at the same distance from Alnitak, though it was not on top of HR1950. Look carefully right below Sigma Orionis.
No matter what this turns out to be, this is a great image.

Thanks Sedat, maybe you're right, but I find it strange that the reflection is perfectly centered on the star in all my raw during 2.5 hrs. also I use dithering and the star isn't on the same exactly position in all the frames

Colors are a little bit pushed but I think that the overall results is extremely good.
I have the same star effect as your in all my sessions and just only on a single star at bottom left of the images. This is probably due to some dirty stuff on the Baader filter.
