DaveS's Obsy Build Thread

Not at all, happy for any suggestions.

Two of the hold-down blocks have been replaced, just a matter of finding time in between doing the other obsy work to do the other two. They have been cut ready, now to fit them.

We don't get much snow here, last year it was just a dusting, and no snowfall this winter.

The roof is, as you say, much too light. I should have had a look back at my original plans which *did* call for heavier timbers when I was putting the orders in to Wickes. I was also trying to keep the height below 2.5 metres for the "Permitted Development" rules.

I think I can use 45 x 70mm beams on end. Will investigate the geometry.

Cool. Development and city/township rules, they vary so much everywhere and some I have heard about are downright inhibiting.  The city where I live has its rules like all do, but as far as sheds/buildings/observatory, etc. go, the limiting factor is size, not height, and is fairly generous. There are actual dimensional restrictions (floor square feet) but rule of thumb is you can build anything without a permit as long as it not large enough to accommodate an automobile, which would then classify it as a garage. That gives a fairly wide latitude considering the size of the average auto here in the USA.
As always, nice work Dave. I will be returning every so often to see it progress.

Where I live is in a "Conservation Area" which puts another layer of rules on top of the ordinary Permitted Development regs, including what area of building you can put up more than 20 metres from the main building.

At least this isn't a "Listed Building" else I'd have had to get planning permission for any structure within the "Curtilage", ie the grounds next to the house.

Another photo.

The beam runs the length of the roof rail, doing two jobs, providing a secure anchorage for the toggle as well as providing a barrier to rain being blown under the roof. It will need a coat of Creocote as it hasn't been tanalised.

The other three are pretty much the same.

Slapped a coat e of Creocote on the beams this morning, had roof open most of the day for ventilation.

Been doing some fiddly jobs around the 'scope and now feel confident enough to leave the TG cover off.

May try to get the door hung if my back is up to it tomorrow.

Waiting on the Chroma filters before putting the camera on.

Time for some more photos. Been installing the roof automation.

The motor

And the control box.

There are two mains leads, one connected directly, the other through a UPS. When there is a power cut the software will park the 'scope and shut the roof.

And a shot through the door of the whole interior.

Great progress Dave.
This subject and the nice work you have done has gotten me to thinking about building another small garden house/shed myself, not to be used as an observatory (I do not have a good vantage point for a fixed scope/obsy due to sky obstructions of neighboring trees), but rather one to store my telescopes inside of year round so I don't have to carry them out of the basement, up stairs, thru doors, then down deck stairs and into the backyard every time I want to observe or image. Naturally, I would have to insulate it fully to protect my equipment as I am a stickler for that. The winters here are hell regarding the cold and snow.
