One of our favorite ornaments... push the button and he says "The force is with you young Skywalker...... but you are not a Jedi yet." A bit hard to tell, but his light saber glows, too.

Hmm... But if it has six-blades, then the opening is always hexagonal, so why does the size matter?
Someday, I'm going to have a camera that has a minimum aperture lower than f8... :cry
The aperture should be round fully open, because the blades aren't cutting into it. It then changes shape toward a hexagon (in this case) with smaller apertures depending on the shape of the blades.
The reason we see stars (pun intended ) is diffraction. Each corner in the aperture causes two spikes. However, in apertures with odd numbered blades two spikes overlap and we see 2n-1 spiked stars. For even numbers of blades all spikes overlap with one other spike and we get n spiked stars, n being the number of blades. That's how Nikolai counted your blades
Edit: Also, diffraction effects increase with smaller apertures - hence the f/22 test.
Wow, is it still Xmas somewhere?
Nice shot, but just a reminder - pictures should be taken fresh, i.e. AFTER you have learned after the assignment. No archives! :nono

Thanks for the entry!

My lights are lot less Christmasy-looking, but I like them anyway ;-)
For some reason I got obsessed with this particular detail of my living room today... I took 75 pictures of the damn things!
Also, can anyone explain to me why an f8 aperture made my lights star-shaped?
As to the star - you should try f/22, they will be much more pronounced.
Hint: you camera's diaphragm has 6 blades..

BTW, Weronika, that's how 7-blade diaphragm star looks like
Another contribution.
