I've recently purchased a (only used once) 20' shipping container. Added two patio doors, one inside to separate telescope room from control room and one patio door at the entrance (behind the steel doors. My plan is to build a torsion style roll off door operated by a garage door opener and controlled within. Most of my ideas took in consideration the ventilation, insolation and electrical requirements needed to operate a total EA system.
I would like chatting with some of yous who have taken or are considering this similar approach to share knowledge on what I believe is a strong, weather resistant, somewhat mobile building. One of the biggest plus of this type of observatory is that you can place it remotely where you would not have to be concerned with anyone accessing your precious gear. The locking system is almost thief proof where the only access inside would be to grind out a hole on the side. My experience with these types of individuals is that most commit these crimes as opportunities, any effort deters' perpetrators as the equipment does not sell without being noticed.
Once my pier base is set in place, all I will have to do is cut a circular hole in the floor to access the pier and drop the container dead on the pier and raise off the ground and level. Vibrations will not affect my viewing as the only connection to pier and container will be a rubber weather/pest resistant shield. I can post pictures upon request but only for those interested in this topic.
