the apod from astromart: http://astromart.com/viewad.asp?cid=239555 claims to be taken with refractors, a tak & an ap155.....why do the stars have diffraction spikes?

I thought the same thing when I saw it...

I placed string over the dew shield in a + configuration
for two reasons: aesthetics and to bleed off some of the stellar intensity which results in less star bloating and better star colors. Hope this helps.

Sorry to raise a dead thread, but while you guys have the 3D glasses out to view the new mars photo, you have to see this one in 3D !!!
