You can still get diffraction spikes with camera lenses - they are "generated" by the edges of the aperture blades...

You can reduce them by adding an aperture mask to the front of the lens and shooting with the lens aperture wide open...

ahhhhh i didnt know that i rather like them my self, but i know some people dont thanks peter. i was really really supprised i could see m57 in that picture... its quite faint (althrough i am assuming its where i think it is) but the kson is supprising me every day! 1 star allignment (and it decided the moon was better option) alligned it through the camera viewfinder (the middle square) and it worked perfect! even went back to the moon, then jupitor, and even vega all in the middle square of the camera
