Hi,

May already know it, but I suggest you not to point it to the sun nor look at the sun thru the telescope. Pointing it may bring the mirror to very high temperature (see a telescope as an amplifier for light and see heath as energy taken off from light. Telescope is a heat amplifier) which may break it. And, as your eyes are less strong than aglass miror, looking at this amplified light with your eyes will break them as well, which can be, at the end of the day, a problem !

Probably stating the obvious, but on the 20th don't look through it at the eclipse.

I have a small astronomical telescope which I use from time to time. I found it a bit tricky to begin with and the advice already given by d.browning should help.  There is also lots of stuff on the internet that might be of help to you. I have a programme on my computer called 'Stellarium' which is a very good interactive guide to the night skies. It was a free download and will let you know exactly what is going on above your head at any given moment.

i'd recommend you buy "star ware" by philip s harrington: isbn 978-0-471-75063-5

you'll get all the info you need about all the different types of scope, and towards the back loads of info about how to best use them. couple that with a star atlas plus a decent piece of software and off you go. don't try to use it indoors, your images will be affected by heat, and take the scope outside an hour, or so, before to get the lens accustomed to the outside temperature.
