The Pro-Dome PD15 model is a complete fifteen foot diameter fiberglass observatory for standalone use. It includes four dome quadrants, rear cover, shutters, dome support ring, 12" high base ring (with molded semi-door section), locking hardware, stainless steel assembly hardware, caulk, and instructions. The optional fifteen foot diameter, 12" high Wall Ring (WR15) matches the PD15 base ring. One or more wall rings may be stacked to increase wall height of PD15. Includes molded semi-door section and hardware. The standard colors are white outside and dark blue inside. Special colors are available and we can do a color match from a sample you provide. Fire retardant can be added for additional protection in fire danger areas.
For robotic operation, the Digital Dome Works (DDW) option provides a computer based automation system which allows you to open and close the shutter and control the dome azimuth so that it matches the telescope position.

Preassembly: The dome is completely constructed, with all accessories (except rectangular/circular skirts), and then put through a complete series of "working observatory" tests. When disassembled for crating, as many parts as possible are left in place and seams are carefully marked. Walls can be crated in "stacks" rather than individual ring sections. Observatory Solutions provides detailed reassembly instructions with the preassembly option.
Custom Exterior Colors: The dome exterior is color matched from a sample you provide. The color pigment is in the material and not a coating. Fire retardant can be added for additional protection in fire danger areas.
Wall Ring: Fifteen foot diameter wall ring, 12" high, matches the PD15 base ring. Seven pieces with semi-molded door. Wall rings may be stacked to increase wall height of the PD15.
Digital Dome Works: A computer based automation system which allows you to open and close the shutter, and control the dome azimuth so that it matches the telescope position.
