Hi,
The only NGC 3628 was enhanced by a mask from an image of mine taken with my R.C. 14" f8+SBIG STL11000
So that's how the diffraction spike get onto the image...
Have a nice day.

No, the spike on the bright star is simply made with Photoshop's Plug-in. The mask was concentrated on NGC 3628 do too enhance detail.

You really bring out the colors well!
