The Home-Dome HD15 model is a complete fifteen foot diameter fiberglass observatory for on-structure use. It includes four dome quadrants, rear cover, shutters, dome support ring, 12" high base ring, stainless steel assembly hardware, caulk, and instructions. The HD15 also includes electric shutter and dome rotation drives with power supply. The optional Circular Skirt (CS15) is a five piece skirt that ends in a 15' 8" diameter circle with drip flange.
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 standard dome exterior color is white. Special colors are available and Technical Innovations can do a color match from a sample you provide or you may request a color chart. The color pigment is in the material (not a coating.) Fire retardant can be added for additional protection in fire danger areas.
Circular Skirt: Five piece fiberglass skirt to the make transition between the circular observatory and circular buildings, or to keep water away from the foundation. The horizontal flange of the circular skirt fastens over a wall.
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.
