The cost of hobbies

While talking to the guy who's had my scope for the last few months (getting it back from him in preparation for sale) I started adding up what I've bought and sold for astronomy over the last 16 years, and I think in the end I've paid about $90/year for astronomy. Even including TVM, it's probably only about $120 since it's weighted more towards this end.

Probably pretty cheap as hobbies go, really.
