Outdoor observatory
I seem to recall you built a backyard observatory. Something like a shed, but the roof folded off for observing.
I have a 6" dobsonian mount that never makes it outdoors anymore. I can make out half a dozen Jovian moons with it, but have never really been able to find any of the M objects. I never really got the hang of the azimuth stuff, so I mostly just point and shoot at bright objects or the moon using filters.
I've considered selling, but its not worth enough to bother and I keep thinking one day I'll figure out how to search the sky with it. Just not enough time anymore.
