I demolished a barely used rotten shed and realized that it had a nice concrete pad under it.  It was facing South so I decided to put a simple obsy on it just for that part of the sky - because that's all the space I've got besides the driveway where I normally set up.

 

The design is as simple and as cheap as it gets.  It is a 6x8' metal shed modified to make the roof a lid that I can slide off and on with 2 handles, no rails.  The shed was $490 after taxes, the handles $30, built with some plywood and 2x2s cut from 2x4s from the old shed.

 

Here's how it works, I'm pretty happy with it.  We have grey and wet weather so I didn't set up my gear in it yet.  I have yet to seal the cracks under the wall that let water in.

Not bad at all.  waytogo.gif  I believe that I would have some type of roof latch on it.

As Carl said, you need to tie down the roof. The wind will take it into the neighbors yard.  Nice setup.

Thanks for the replies and the suggestions! 

 

I added 4 latches.  Simply by drilling holes through the 2 adjacent frames (walls and roof) and sticking a nail through it held in place by a rubber band.

 

I rounded off the edges of the roof frame a bit and practiced keeping the roof straight when closing.  Now it doesn't bump anymore.  I think I am all set.

I added counterweights that make lifting the roof very easy.  Here is a movie that shows how it works: http://haling.synolo...13438372e4d4f56

I never posted a picture, I should have.  Here is one.

The observatory is a success!  Imaging is now easy.  I may only have one quadrant of the sky, but that leaves plenty of targets to keep me busy.

 

With the counterweights, it does not take much effort to put the roof back in place.  Having it 5 steps away from my dining area's sliding doors is handy too when you have to fix something manually.  The WiFi works fine once you figure out how to network the WiFi repeater. 

 

I have put all my telescopes and gear in it. I hope it stays dry in the rainy season.  I filled the gaps below the walls in with yoga mat foam then caulked it up.  Hopefully that will be sufficient to keep everything in there.
