Observatory opening size
Hi everyone. I'm making the frame for the dome on my observatory at the moment and I was wondering if someone could tell me what a good size for the opening is. At the moment the opening is about 80 cm wide but I can make it bigger, I just have to move a couple of bits of timber around. The dome is about 3.8 metres and I am going to put a 12 inch Cassegrain on an EQ mount. I live in light polluted skies about 30 ks from Melbourne and I will be using it mainly for photography and the dome is not motorised. It's not a true dome it looks more like a flattened dome or like a traditonal vietnamese hat.
