Observatory Dome

Design concept using the RCO Simplified Dome with  retrofit sky viewing slot.
These drawings are based on the 18 ft dome with X1 addition.


The top half of the dome with -X1 struts removed. The Base Perimeter now has 16 edges. The view slot is shortened at the top where the apex Connector Hub and top 4 struts remain intact. This dome can be mounted on a riser wall where a door can be placed.


Diameter to height ratio of the RCO-S, top + base is 1 : .6785 For example: 16 ft diameter X .6785 = 10.85 ft.

The original observatory design, with -X1 struts removed. The -X1 struts are not required on smaller domes, 10 - 15 ft.
