I'm quite lucky. My partner likes the outdoors and country, but not the cold. She'll find me new locations to observe in the country where she can photograph the native critters and I can do observing, works out very well.
She only views stuff when there's a group around and she can be chatting to someone (I'm usually quite absorbed in it, and busy telling the scope what to do, so not good company).
She makes a point of mocking the names we give objects, referring to any globula cluster as "A sneeze" and in particular 47 Tuc as "the sneeze", Rosetta as "the skull" .. and I can't remember which she thinks is an elephant... it's makes it entertaining anyway
As for buying stuff etc, she's a little more tough on that, but only as far as is practical - we do need to pay off the house after all. I tried to sell her the idea of a $90,000 Allira 20" system on the weekend, she didn't give me the OK
The biggest problem is when I want to observe late and go to bed at 2am, waking her up. Do that a couple of nights in a row and I'm not too popular.
Roger.
