An update for you all who are interested...
The changes from my last post are an undercoate and topcoate of paint everywhere inside and out, white on the outside and flat black on the inside.
The other addition is I have added all the enclosures that will house the electronic equipment and conduit to go between everything and all around the Observatory. All the wires are in conduit for organisation and to keep rodents away from cables. I chose to use large conduit and a junction box on every corner so there will be no problems pulling cables around corners or if I want to add more later on.
I have separate conduit for Ethernet, 240 volt AC and various voltages of DC electrics.
Next is to add the wires, the fun part
The white conduit bellow the enclosures is for air ventilation for cooling electronics, the air comes from the 2 fans in the Observatory, which is pulled from outside.
Cheers Josh
