Hi all. So few weeks ago I did a post asking about diffraction spikes for my Rasa 8. So after some few helpful tips I decided to have a go at it. But the diffraction spikes on the star Arcturus is not perfect and I'm not sure why. Any advice is appreciated. I'm going to attach 2 images.

The cross is the spikes created by the fishing line.  

That other spike is something created by your RASA.  Probably the camera cords.  

Rotate the fishing line spike mask until you find where you like it.   That's all.
