Objective Lens Mount

why should you always use the low power objective lens to locate objects mounted on the slide first?

Because it's easier; you'll have a harder time locating anything if you are under high power and only looking at a tiny area of the slide.

does anyone know what should i be able to see with this ? i have no idea how to use it, it came with a 10,000 item sighting CD but its so confusing to use, anyone here pro enough to tell me what should i be able to view with this scope, or any websites that can tell me what i can view...

thanks for your help

This is similar to my first telescope. With it I was able to see the Moon, Venus, Mars, Jupiter, and Saturn, many double stars, and over 50 deep sky objects, mostly open and globular clusters, but also some diffuse and planetary nebulae and galaxies. It's an OK beginner's telescope.

There are a number of books which will help you learn to use your scope and find these things with it. Try NightWatch by Terence Dickinson (Firefly), Turn Left At Orion by Consolmagno and Davis (Cambridge) or Star Watch by Phil Harrington (Wiley). Joining a local astronomy club may also help, since clubs usually hold observing sessions where the more experienced mebers help the beginners to find things in the sky.

One piece of advice. Don't bother using the 10mm eyepiece or the Barlow lens, as these are usually junk. The instructions which come with Tasco scopes are usually poorly written. Try using these instructions for a similar scope instead:
