I know these have been discussed in the past, but its been many years. I came across this one online at www.astroshop.eu/instruments/omegon-tent-observatory/p,12278

I think I could get some use out of this, even if its just leaving a polar aligned setup outside for a week of potential clear nights. It's also just about 4.5Kg which makes it quite portable for travel to dark sky sites, and is about the cheapest I've seen at just €179.

 

Hi John,

I have one of those (or a very similar one).  It works quite well except the roof/lid on mine is not quite big enough to properly keep the rain out.  I ended up buying a patio table cover on Amazon to act as a 'roof'.

When the lockout ends I can drop over to you if you want to take a look.

Michael.

Thanks Michael, hopefully we can all  meet up some clear night after this ends. I think I'll be heading for Lugalla once we're let back out to play
In the meantime I found this review of the tent on youtube:

Hi John,

That's the one I have.

Michael.
