In which case a good telescope won't really help.However, sometimes it might be good.A colleague has just bought a Skywatcher Evostar 120mm ED Pro refractor (£1160 Sherwoods for instance) and Sky Tee altazimuth mount (~£400).This seems good value for an Apo or semi Apo 900mm focal length f/7.5.The specs say it will take up to 360x magnification, which I see no reason to doubt.I await his reports.Some say the dovetail bar is too short etc. and I think one may need counterweights as the mount will support up to two 15Kg telescopes.I would choose this over a Swarovski 95 or Kowa 88mm.With regard to large binoculars or a binocular adapter the problem is that visitors don't get the IPD or the dioptre correction right and I think they are much better off with a single eyed view.It would not surprise me if the view at night over the Bay at say 10 p.m. would be good.There is no reason not to view then as there must be lot to see in a brightly lit city.</blockquote>
