Pro Golfer Jimmy Walker

Saw this featured today during the Pebble Beach Pro-Am. Pretty cool stuff he does when he's not playing.

He post's on Cloudy Nights forum and does some amazing work!

Thanks for the link he does some great stuff. Are the "lines" of light from the stars "natural" in images like the Horsehead Nebula or is he adding them in post? I think I heard of software that does this but can it be achieved "naturally"?

Some mirror based telescope designs have mechanical supports for a secondary mirror that cause the diffraction spikes. Some people like them and some go to great lengths to reduce them. There are also software tools that can add them in.

Thanks Steve, my dad just mentioned that there are filters that will do this as well (physical ones not plugins).

You don't need filters. Put a couple pieces of string crossing the front of the telescope in an X. You now have diffraction spikes.
