Before you commit

Aquarium Keeping

  • Losing a few fish to a tank that cycled too fast would gut you.
  • You want results now, not weeks of patiently waiting out the nitrogen cycle.
  • Weekly water testing and partial changes sound like a chore you'd skip.

Astronomy

  • You want instant results, not twenty minutes nudging a scope at a smudge.
  • Orange suburban skies and light pollution would just frustrate you.
  • Standing alone outside in the dark cold isn't your idea of a night.
