Temporary observatory / light pollution shielding

[Stargazer51N]

Has anybody experimented with temporary observatories (e.g. Tents, gazebos, awnings, etc.) or light pollution shielding?

Due to fences and trees the best place to observe from in my garden is smack in the middle - so a permanent observatory is not really an option. I wondered if it would be worth rigging up some temporary screens (canvas or tarpaulin for example) to block out the worst of the LP from my neighbours. I have tried getting under a large sheet of darkroom fabric (covering me and the eyepiece end of the scope) - this is an improvement, but rather awkward!

Anyone got any ideas?

Some folk have made frames fron plastic trunking (the stuff used to run cables through, about 25mm diameter) to make a frame and then hang/fasten sheeting to that. You may find details in the DIY section.
