Had to drill a few holes because our moron builder set the panel 2' below grade. Mast comes in and is covered by drywall. Each hole we drilled hit concrete. We managed to find a spot, at the EXTREME top of the panel! We used a spare 15amp.

Inside the observatory is a 15amp GFCI. The door cover will be replaced with a wall plate once the dome is on and secured. You will notice I only have the two plugs and no switch. I did this because I wanted to keep it simple, straight line in. I will use the switch at the panel to turn it all off. I have a headlamp, no need for lights. I have a red rope light for the pier plus a 2 to 6 plug surge protector. I will just use zip ties to keep the AC brick to the side of the pier.

Later in the day I started moving the dome, what you see here is the Skyshed POD dismantled and pressure washed. Used a shop vac to remove any water left behind in the PODS.

Laid out the walls and pods according to the 10x10 deck on the Skyshed POD site and because I am offsetting to the North (direction of the pods) it means that they sit quite a bit over the edge so I have decided to go back to the 1 on each side of the door and 1 in the back configuration, more pics on that later.

removing the cardboard is impossible! the company who poured it didn't use an releasing agent, I tried Trisodium Phosphate, soap and water and a pressure washer. Figure, just leave it.

You can see I have lots of room out front. PODS face N and wall faces S. I still have to go a few inches North but I need to get the scope mounted before using the lag bolts.

You are going to enjoy having your own special space.

After months of calculating, doubting and wondering if I measured right, I am happy to report I officially have 1" of clearance! I might have more once I adjust for the north offset.

I might have to turn the OTA 180 degrees if I run out of room, hopefully it doesn't mess up the balance to the point I have to move it further up the dovetail.

You don't mean to use the breaker to turn it off, do you?
Not a good idea. Breakers are for safety, not as a means to turn power on and off.
If I am mistaken, please forgive me! I would not want you to have a false sense of security.

He's required to have a switch. For 120V, you're only required to have a single pole switch at the out-building to control it. He means that, I'm sure.
Jeff, thanks for posting that. I'm going through adding 120V at the shed and it's nice to see how you did it. Did you have it 'trenched' or did you use a vibratory plow?

I hired a company to do it, the trench had to be over 100' long and I can't dig that and Home Depot rentals do not rent trench diggers here. They brought a mini excavator in and dug it down two feet. Power is direct bury but I put in in conduit, the ethernet is direct bury without conduit.

I bought some 1/2"x4" Lag screws and bolted the Skyshed POD down. I am 3 short, no big deal I can get more. I had twice as many washers, maybe I have another bag somewhere.

Next thing I did was take the scope down and the CGEM mount so I could attach a teflon based material down on the Starizona CGEM plate, pay no mind to my crude drawing. I wasn't sure after peeling the sticky side whether I could see through it so I measured to be sure.

You can see after sticking it down I could see the holes that I need to cut out:

Finished cutting away the access:
Teflon, to help with Azimuth movement by AstroJeff, on Flickr
Anyone with a CGEM knows what I mean when I say that moving the mount in Azimuth using the knobs and next to impossible. Too much friction, even with the center bolt loosened. You turn and turn and turn and nothing happens. Then its that last frustrating turn that the mount finally moves the amount of the many turns. With this teflon substance it is as smooth as a baby's bottom and I have to thank a fellow member of CN (ORION58) for packing up, sending and paying for postage to send me the teflon substance he had left over. It is people like him that truly makes being part of this extended family we like to call CloudyNights an amazing experience.

I would worry about strong current surge induced by lightning strikes. I've seen underground cable runs that were never affected but I have also seen some 40 ft runs that burned out electronics repeatedly from ground lightning strikes up to a mile away.

Thanks for sharing your experience & suggestion for the OP.

The power run is from the panel to the switch and only one circuit. I will look into putting in a switch.
