The telescope you refer to is a good entry level small newtonian reflecting telescope mainly intended for astronomical observations although some of the catalogues suggest it is suitable for terrestrial observations as well but there is no mention of an erect image eyepiece or prism and without one the image will be upside down.

It will give good views of the moon.  It should show the moons and basic details of Jupiter and Saturn and the phase of Venus and maybe a bit of detail on Mars at opposition (as it is now).  it should separate double stars down to around 3 seconds of arc  say castor in Gemini and show the brighter nebulae like Orion and Andromeda.  Get out and use it as soon as possible all these are visible at the moment!

The best way to find out if it's any good is to try looking through it at Saturn (look for a bright star which doesn't flicker, somewhere to the south east in the late evening - you'll know it's the right one when you see it because it'll have handles) and see if you can detect its biggest moon Titan - you should be able to see Titan moving from night to night, so you'll soon find out if it's really it or just a background star. With a birdwatching telescope it's possible to see Titan if you don't look directly at it. If the optics of your telescope are any good, you should still be able to see it even if you look directly at it. If you have trouble finding Titan, get your eye in first by watching the moons of Jupiter for a few nights (though it isn't well placed any more - look for it in the west at first dark).

Nice tips David.  Jupiter and Venus have been nice companions for me (and each other) on my walk home from the station every night for the last few weeks. 

Kierae - you can use this site to work out where to look in the night sky, or understand what you are looking at

Plug in your coordinates (I use the compass ap on iphone to get mine - although because I basically live on the prime meridian I can normally remember 51 N 00 E) and the time and you get a star and planet map.  It will take a deal of time to work out what is going on - but that's the fun.

You can see an erect image of terrestrial scenes by standing beside the front of the scope with the top of your head toward the back of the scope.
