NexDome Deck Underway South Coast
Finally started prep work on my deck on the South Coast NSW for a NexDome 2.2m observatory which is due to arrive late January 2021
I opted for an elevated H4 framed hardwood deck 400mm FFL in lieu of a concrete slab as I wanted to have a 360 deg clear line of sight from 20deg up at the rear of my property which has a narrow backyard.Due to the tight space, the 2.2m Nexdome suited my situation perfectly.
There are 4 piers 250mm dia , one central pier for a future pier mount and 3 tripod piers which will be used for now
Underside of deck will sit 6mm above top of pier level with 3 x 80mm holes drilled through deck boards for tripod feet in the final polar aligned position ( Also provision is made for a bigger EQ8-R mount either pier or tripod mount in the future ( I currently use an EQ6-R mount )
A trench has been dug from rear of house to deck which will carry a 230V 20A dedicated power circuit and 2 x Cat5e UTP data cables in HD underground conduit. Dual data outlet is already fitted off in the house ( Study )
Next step is the deck footings and galv stand off brackets then framework
I’ll update when frame is completed
Cheers
