Just curious Peter - what's your northern horizon like? What's the lowest angle objects you can see in the direction?
There's a few low N messier objects I'd like to capture. I'm hoping to get some shots at Ron's this Sat, but wondering if 10 Chain is ok to the N (lower than 20 degrees off horizon I'm talking). Realise seeing etc is likely to be rubbish that low.
Ta,
Rob
