    Well, time to shoot my Zero Image 4x5 pinhole into space... it has a rotating disk with besides three pinholes, also three fresnel / zone plate "lenses"...

    See if I can capture some aliens!... :D

    I would rather say "Zone Plate Telescope"

    I was contemplating a pinhole for deep UV shots into the sun. Problem is that the bloody atmosphere probaby blocks the deep UV, and I don't yet have a spacecraft.

    Xray telescopes use zone plate technology to focus the images so this is nothing new to astronomy. The newness of it is the wavelength involved in the imaging.

    Cool, just seemed like something that might be of interest here
