telescope!!!

one of my cousin wants a telescope for a birth day present , but i don't know which model should be good for beginner (personally i don't have much interest in it). i am planning to buy a medium range telescope for her. issue is i don't know what configuration is good. i searched on Google which gives it's parameters like focal length , focal ratio, even there are two types terrestrial and astronomical and many more configuration. If someone has used/know about that can you please suggest me?

Aperture width is much more important than magnification - the more light it collects, the better.

How far from his window is the pretty lady? :laugh:
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

:laugh: :laugh: :laugh: for that purpose one can use video calling feature on the smart phone. you won't need a telescope for that.

He means the other pretty lady. The one that he can't call due to a court order.

You don't think his cousin is going to be pretty? :laugh:

There is an expensive Celestron model that takes a database of stars' locations and lets one train the telescope on any specific star one chooses to view, correcting for one's location on earth. Locating a celestial object should be easy as pie with that device.
Used one of them about a decade ago. It was incredible. At the time, GPS and electronic compasses were simply not available for the inexpensive mass-market, so we had to tell it the lat/long and also orient its base. From there, it knew where it was and what it was looking at. It even had a feature that would take you on a tour of sorts, visiting interesting bodies along the way. It was rather small and nothing like the 18" diam one we've looked at the moon with, but the tour left us speechless. That was by far one of the neatest things I've played with. Using a manual one to look at the rings of Saturn was another exciting moment. Too bad I didn't take a 35mm photo - that'd be neat, having a negative that was chemically changed by the light that had actually bounced of the surface of the ringed planet.
"When I was 5 years old, my mother always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up. I wrote down 'happy'. They told me I didn't understand the assignment, and I told them they didn't understand life." - John Lennon

Of course not! :laugh: I missed the "her" is all.

Best thing to do here before spending any money; find a local astronomy club and attend one or more of their skywatches, or stargazing evenings. Something similar to this is ideal: http://nhastro.com/skywatch.php[^] This accomplishes several things, all without spending lots of money on equipment. 1. it gives you exposure to astronomy as a hobby. 2. It gives you a better idea of whether there is a true long term interest in astronomy. 3. You get to sample a variety of telescopes and their usage. 4. You meet a bunch of hobby astronomers that really know their stuff. A good telescope is going to be fairly expensive. A cheap telescope is much more likely to turn the budding astronomer away from the hobby than anything else.

A friend of mine had, as a child, a 6" newtonian reflector with a manual (not motorized) equatorial mount. It provided enough detail that we could recognize nebulae that we'd seen photos of, and brought in enough light that you could use it successfully in the city. It was easy to move outdoors when he wanted to use it. The mount doesn't matter a bit if you're going to use your own eyes to look at stars. It matters a lot if you want to hook up a camera, because an equitorial mount tracks the stars' motion with a single degree of freedom so you can make long exposures. In those bygone days of film that wasn't an issue for kids, but in these digital days, it might be. It was pretty fun for a summer, but after a couple of years he had moved on.
