Please help me to choose a "TELESCOPE"!? - 8 inch newtonian astrophotography
I watched the stars for some time with a 7x50 binocular, and although better than watching the stars with the naked eye, since I do not see much with them and I) live in London (United Kingdom, as well as you can see the light pollution and the UK weather imagine, does not help us much. I want to buy a telescope, but do not know how to choose a beginner. A refractor, reflector or Newton? That the inclusion of 6 inches (150 mm) or 8 inches (200 mm)? What about the computer, "Go To" telescope? And they are expensive? Please explain. Thank you!

8 Inch Newtonian Astrophotography Please Help Me To Choose A "TELESCOPE"!?

Firstly, this is not the best place to get advice about telescopes. There are very few people here that also telescopes, let alone anything about them. I recommend the same question in a forum with users, such as "Talking Telescopes"

But you have to do homework. To get started, here are some excellent articles about telescopes for beginners:

For the treatment of deep, read the book by Phil Harrington's Star Ware (Wiley), 4 Reprint.
Many of the answers that were previously a tendency of the United States, most U.S. retailers will not be delivered to the UK site with excellent views of the United Kingdom, Steve Tonkin is the astronomical unit:

Personally, I have helped dozens of beginners, to start, and the best telescope for most of them was an 8-inch and 10 inch Newtonian reflector on a Dobsonian mount, sran as follows:

Computer GOTO add a lot of money for a telescope, usually at the expense of optical performance. You better money for an area with good optics and learn to find their way into heaven itself.
Try to imagine all www.bigbinoculars.com YouCan have to watch out for low-cost very high. Great website.
I agree with the election of Geoff, an 8-inch or 10-inch Newtonian telescope, but I would choose a location in the equatorial mount. It is more expensive, but it will be easier for the stars and follow eventually, you can mechanize. If the budget is limited to elected and thus the largest diameter mirror.
Another good option is more expensive telescopes cathadipotric. It depends on your budget. Please look at the sides or Celestron http://www.celestron.com/c2/category.php Mead ...

I would not choose a telescope, for example. The larger diameter are very expensive.
Eye are also important. When the telescope comes with Huygens or Ramsden means that quality optics are very good. Kellner or Plossl are much better.
Your choice will ultimately depend on your budget, try to gather as much information as possible. I can also say from experience that if you really try to look like the stars, you, the largest telescope you can afford to choose. You can last a long lifetime and a telescope to the very small size can disappointing in a few years. Good luck!
You get more money for a telescope. In the old days of heavy basic telescope was a 6-inch Newtonian reflector, but is now a day a Schmidt-Cassegrain 8-inch, often controlled by the computer. The Dobsonian is an inexpensive way, a simple manual Alt-Az Mount Newton, often very large as 12 inches or more.
Take a look at the sources.
The "forbidden zones" with GPS are often very expensive.
In general, the more open the better. A "mirror" and "Newton" are more or less the same. I prefer that "refractors.
The only solution to the lighting of the city is out of town if possible. They are not much smaller than the moon and the planets in London.
