We came across what we think is a great idea for an observatory for winter.
:: It's a very solid construction. 38mm powder coated steel tubing frame with click together design
:: Cover is very strong heavy duty polyester weave
:: 3 mt wide 2 mt deep
:: Wind resistant waterproof and very sturdy because of the ground level frame
The front veranda can be rolled back to the first bar for a higher elevation when using with the roof on
The roof can be removed completely to observe at zenith
Rear entry with centre zip or rear cover can be removed
The front window can be zipped to enclose the whole unit for cozy observing when viewing with the roof off
Once erected and you want to change your viewing the whole unit can be lifted and turned to face the front in any direction ( We may add wheels to ours for easier rotation )
3X2 mt gives us plenty of room inside for ourselves the two scopes tables gear and two chairs. If your into imaging there's plenty of room for laptop gear etc.
Lots of options with this great unit very strong and sturdy. We think it would be great for astro camps also .

With the temperature sometimes getting close to zero here
we definately needed something.
We now have a portable observatory for the colder months at a
very affordable price 
We've packed it away now until needed.
We can't wait for those clear dark winter skies
