This is the reason why I started photography. I was very interested in Astronomy and wanted to dip my toes in Astrophotography.

The Moon on 31st July 2004 - EOS-1Ds, ISO100, 1/60th sec, prime focus, VC200L, PS

Comet Halley March 1986 - Canon something-or-other, ISO400, PS
These were taken when I was 15 or something.
