The makers of kitschy commercial religious art of the Christian persuasion should be grateful to the telescope builders of the world for so often putting the secondary mirror struts in a cross shape.

Six-pointed stars come from telescopes with three vanes. And maybe from use of an iris with x number of blades?

I was going to make a joke about how such photos would figure prominently in Cylon religious art. But I couldn't find a good picture of an old-school shiny Seventies Cylon shot through a six-pointed star filter, the way they used to do it all the time.

Aah, I've seen that. It's in Toronto and we googlemapped exactly where it is. ^^

And, yes, I've seen six-pointed stars with my Canon S2 IS by shooting bright lights with the aperture stopped down as narrow as possible (while I was trying to shoot fireworks).
