I've a roll-off observatory shed installed in my backyard and it does its job (it survived two thunderstorms, so far..). Now, I'm planning to permanently install a 2nd scope, but unfortunately my current observatory shed is too small so I'm looking around for some ideas.
What I'm considering is to buy a dome-like observatory like either Skyshed, NexDome or ExploraDome. However, I do imaging, so I'd need the dome to follow the scope through the night, i.e. I need reliable automation which apparently is not the case here, at least according to what I've read around. So, I'm wondering if any of the domes listed here above can have the dome quickly and easily removed (and reattached). In other words, I was thinking that I could buy one of these domes in its basic version (no automation, no motors), and then when I do imaging I do simply remove the whole dome in order to have a full clearance of the sky. So, I'm wondering which one of the domes listed here above is the simplest one to have the top dome removed, if ever possible. Would it be something which requires just few seconds, or several minutes?
Of course I understand that it would be much easier to build another standard roll-off shed, however I've limited building experience and I don't feel confident in spending more time to build up another one; this time I prefer to go with something made by professionals.
