Oh, Ive been through this dilema

.
Its funny, I see posts firmly stating "Id never spend lots on just a hobby", or "its a bad investment", as if houses, cars and investment returns are critical to the pursuit of happiness. And hobbies are not worthy because.................well, because they are hobbies, no other reason other than some percieved, socially derived "importance".
Seems to me, a hobby, given the TIME invested in such, can give a greater return in general well being than a house or a car, or any other utility device. (given you have these of course, to some basic degree ).
Astrophotgraphy is a noble pursuit, forefilling, esoteric even, and can give more of a challenge and enjoyment than any mundane "utility".
Its an art, creative, satisyfing. Spend up I say, debt is just a passing irritation, easily forgotten, just eat less
