New observatory

My mount is a Vixen SXD with the NexSXD upgrade & Celestron controller.

What stops the roof being blown off by the wind?

I hope this picture will get you an idea of the rolling system.

Yep just what I was after - many thanks!

The roof is locked by 2 of these and another one to keep it open.

Until now it survived 2 storms.

Very nice indeed!!

The shed is also windproof. When the wind blows there is only a negative pressure over the roof and the positive pressure under the roof is lower compare to an open shed.

If I'm wrong let me know it

There are a few other Obby Roofs with this feature a secure hole and a bar/bolt that enters the hole as the roof slides shut, so one end of the roof cannot be raised up by the wind or would be intruders, i surpose this idea could be extended to both ends one internal and one external, then add a couple of clamps inside to stop it rattling in the wind....

This is a brilliant idea the hole and the bar. I will add it also.

An alternative is a captive mechanism like this. The advantage is that it will hold the roof down in any position, not only in the completely closed position.

This system is also good in reducing the air intake.

The scope & the mount are now on the pier. Now I need a good clear night to polar align the mount.

Next job is the wiring for the electricity.

All my equipment is stored in a big toolbox.

looking good, how comes the door at the bottom is wet?

[Astrobug]

It was wet due the strong winds. But not so long ago I added a rubber/aluminium strip on the outside. Wind and water dont get in anymore.

I like your tool chest in the corner. Great idea for kit storage.

[jaspalchadha]

It shouldn't got in the first place the money you must of paid to get it built

On both side in front of the rolling system I added a rotating panel.

It is now much faster to make the shed wind tight.

In the winter I keep it closed and in the summer it will be open.

[Astrobug]

Now I'm busy installing the necessary cables. With 12 outlets, I will have enough.

Along two sides are red lamps.

Fortunately, I've found somewhere old lamps that my grandfather used for his Christmas decorations.

The top of the armature is covered  and through a dimmer the intensity will be adjusted.

The ducts are placed at 1m so that they remain above the worktable.

The maincable comes from  under the floor. The airvents comes handy here. It helps you to place the cable at the right place.  I use a similar white gutter from the floor to the horizontal gutter.

I will place a picture later this week.

Here are a few more pictures. It is nearly done. The cables are 3G2.5mm.

The 2 red lights are controlled by a dimlmer.

I still need to install the light near the door on the outside, it can be put on from the house.

[Astrobug]

1st light was tonight. It was not a long observation (1,5h) with the upcoming clouds and the bad seeing.

[jaspalchadha]

I am installing 100 2 cable and 50 metre of it
