Was looking around local branch of Currys last week, looking for a freezer. Came across a display of telescopes and casually looked through a couple, having recently been seeking out a spotting scope for zeroing, but not keen on shelling out hundreds (or thousands) for something posh.
Anyway I tried a Celestron 70 (40x)and was greatly surprised by the quality, so I bought one for £53. I imagine it will do the trick. Havn't tried it yet but have been reading my neighbour's planning application notice from around 100m.
The inevitable ....but is that the tripod attachment is a bit flimsy.
