The concrete base for the observatory was laid yesterday. What my builder has done in two days would have taken me a month (or three) of Sundays! Next job is for him to lay a single course of bricks to set the wooden base of the observatory on. This will prevent water seepage under the edges of the base and prevent the base from rotting. That’s being done next week and he’s also replacing the rotten and broken fence panels you can see in the photo. There will be a 300mm gap around the observatory for maintenance access. After that’s all finished I can erect the walls and roof supports and then get the boys around to get the roof on!
Once the observatory is erected it’ll be time to kit it out. I’m planning to run a caravan power cable from the external socket on the house to a socket on the outside wall of the observatory. This will be a simple job to connect up each time when I want to observe. I have some old kitchen units and surface to use for storage and a work bench.
A new telescope and mount is going to go in there and once that is purchased I’ll need to work out what height steel pier to get/have made. The commercial ones tend to be in the 800-1100mm height range, I have no idea if that will be adequate yet. It needs to be high enough so that I get as low a horizon as possible but it also needs to be low enough so that the telescope can be parked horizontally without the roof hitting it. I won’t know the ideal height until I have the new telescope set up on a tripod for starters.
