My first scope was a 60mm ebay scope I called it "the wobbletronic".
The 10" Dob was named "The Annie Jump Cannon".

My latest mount, the iOpron Mini Tower was christened "The Tower of Terror." The Strongman, Mike, called it that when I first got it and the name has stuck.
The Cube is "Astroboy" because it's blue and it's got a sticker of Astroboy on it.
