Roberto,

what a nice Image again! I lke the diffraction spikes in this one; how do you proceed?
Small aluminium stripes painted in black or so?

What do you mean by:

"I have changed image after colour stars modification" ?

Hi Lex,
thank you again.
In the first time I have posted an image were the stars show tipical color of this mappature (magenta) and so I changed it with a new image.
I obtain diffraction spikes by two  nylon wires crossed.

Hey,

The good old trick with the crossed nylon wires 
Did you try already to fix them on a wooden circle that simply slips on you scope?
I found that this is really nice for taking them for instance only for the Lum channel..
I also tried to spraypaint the wires in black; this solves a bit the colorspectrum artifact ( rainbow colors of the diffraction spikes )

Cheers

Lex
