For sale in Eltham North, Victoria is a Sirius 2.3m Observatory Dome with powered rotation and MaxDome II automation kit for rotating the dome.
I have used it for Astrophotography and it holds a 130mm refractor with full mono imaging system on the back comfortably. For visual use a 130mm refractor would be too long (room for the scope but not the viewer!).
It comes with one storage bay, 3 shelves and 3 wire baskets, a new battery for the rotation motor, a solar panel to charge the rotation motor, and a 240v battery charger as well. It also comes with a dehumidifier which has a hose egress hole so that you never need to empty it, just let it exit water out through the pipe provided.
The shutter is not automated. The people now running Sirius Observatories do not yet have a solution one can purchase to automate the shutter so please, if you're considering it for remote observatory duties, do your research on how to automate the shutter. I know it can be done with electric struts (automotive boot lift struts from 4WDs for example) and an arduino but I do not know how and have not looked into it. With the dome in my back yard, there was never any need.
It can all be moved in a single load with 6x8 trailer cage trailer - I rented one from the local servo. you could get away with a smaller trailer but you would spend more time shuffling to get everything in just so. Or do multiple trips.
I will disassemble it in advance so that all you need to do is load up your trailer and go. The assembly instructions are very clear, and most of it can be done with just one person. You will need assistance of at least one more person to lift the dome halves up onto the walls.
I cannot facilitate shipping of this thing. I can help you load it into a trailer, or if you want to organise your own collection and transportation I'm happy to work in with that.
