That is an extremely impressive build, I take my hat off to you.

Do you build things for a living or is this just a do-it-yourself project?

Good to see you posting, look forward to seeing more.

Thank you for the comments, I made the pier yesterday and its about 700 kg of concrete 3.30 meters high.

I got some inspiration for the dome of the web but I guess its mostly my own design, but there are similar domes out there.

Im not a proffesional builder but I have been building some things in my back yard, this is my second observatory, first was a small roll off roof.

More pictures are coming soon.

Hello, I have used a tube for the pier, diameter is 30cm and I hope tha stability will be good, but if Im not satisfied I will add extra support to the pier from the walls at 2.40 meters.

I will tell you how it goes when I put the scope up.

Hi, for now the dome is just painted with high resistant paint but I might put on epoxy fiberglass later.

I´ve modelled all of my house in sketchup but only the exterior and it´s quite roughly made.

I meant to ask, I can see the wheels supporting the dome section appear to be attached to the top of the walls and the dome runs freely on top of them. What stops the dome sliding sideways? Is there just a channel in the wood on the bottom face of the dome bearing timber?

Hello, here is the latest update. I'm happy with how the pier came out, it's really stable and I think the stairs mounted to the pier on the first floor gives it a little extra stability.

Telescope is mounted and there is a picture of one of the wheels holding the dome in place.

That looks lovely. Let's hope nobody walks up or down the stairs while you're imaging. :hello2:

Do I see this right? Did you make a pier adapter of concrete? That's an excellent idea!!

Hello, the pier adapter i made of concrete, works fine i think.

The plan is to control the camera from downstairs when taking pictures so vibration from the stairs won't be a problem:)

Hello, I had a 3m papertube that i filled in one go and did the last 0,5m with a slightly smaller tube the day after.

The papertuba was specially made for concrete work with a plastic layer inside so it would be easy to remove.
