Hi Mike,
You can get a good starter scope for about £200. Sky-Watcher are generally a good make, as is Celestron, so you are definitely on the right lines. But I would avoid the Skyhawk 114, because I think it's a complete waste of time. It contains an extra Barlow-type lens of rather low quality to boost the focal length up to 1000 mm so the result is that you don't get good views at high power because of the extra lens, and you can't use it for low powers because of the extra lens. There are similar scopes from other manufacturers, and the supposed advantage is that you get 1000 mm focal length with a short tube, but in my view they aren't worth having.
The Explorer 130 and the Celeston equivalent are popular scopes, and I know that the Sky-Watcher gives good images for its price, but many beginners find that the equatorial mount is a pain. If you think you can cope with it, it offers the chance of tracking a planet using a single slow motion, which is good. The 130M at £179 or thereabouts has a motor as well, which gives the equatorial mount a real purpose, and you could do simple astrophotography by piggybacking a camera on the mount (bu not photographing through the scope -- that isn't so feasible).
But for your budget you can get a 150 mm Sky-Watcher Dobsonian (£199). No motors and no equatorial mount, but a larger aperture, and for me larger aperture is always worth having. That's the sort of scope that Jonathon Ross was shown in preference to his more complicated computerised scopes. Though I have to say that all he needed to do was to read the manual -- the Celestron Sky-Align Go To is very simple to set up though outside your budget.
A 150 mm (6-inch) will show you real detail on planets when they are high in the sky, and will also show a wide range of deep-sky objects.
Incidentally, if you join the Society for Popular Astronomy (
www.popastro.com) you can get a 5% discount from several suppliers, which will virtually pay for the £16 annual subscription when purchasing a scope -- and you get excellent value from SPA membership in itself. But then I would say that as I am Vice President....
