Allan, it's looking like the shutter will have to be 650mm wide minus the shutter framing, 42mm, so about 610mm. It is a small dome, 2100 O/D. I can't make the opening any longer either or the door won't roll round the dome. I note the sirrus domes solve this issue with a flip out door.

Therefore I see a problem with the 10". If it's looking east and then eventually pointing straight up, the dome will have to be rotated before it gets to azimuth or it will not see some of the sky, the slot will not be long enough. I can still move the pier a bit, It's bolted down with concrete bolts, but I'll suck it and see first. If I manage to automate it, I might be able to fix that in software. However I think this is a penalty of having a small dome.
