I can tell you what this guy will do.
First of all what you can do with telescopes is limited by a number of factors many of which I won't go into.
Aperture, or the size of the objective lens, is the most important factor. It determines how much light the telescope gathers. Next is power, and this is determined by the eyepiece and barlow lens. I see the power of this scope with the included lenses is 25 or 50 power. The lower the power, the brighter the image and larger the view.
At those powers with a 2 inch lens what you will be able to see is small discs for the planets. You will probably be able to tell Saturn has a disk and certainly that it has rings, but not be able to see much detail. You should be able to see the moon and it's craters very well. Look at the moon when it is not full, and notice how the shadows are enhanced. You will also be able to see the disk and moons of Jupiter, and if you draw sketches, should be able to note their movement over the course of the night and even better over several days. You will not see detail.
You may be able to see the Great Nebula in Orion, just below it's belt. This is a patchy region that many folks can see with their eyes slightly diverted in a very dark sky.
You will be able to gaze into the Milky Way, and imagine just how many stars are in it.
You should be able to see small star clusters, like the Pleiades, or Seven Sisters, in the
constellation Taurus.
There are a few more great things to see, which are detailed better here:
http://irwincur.tripod.com/ten_best_obj_-_small_telescope.htmThe problem you will face is how to actually get the objects into your field of view. You will need some kind of mount, camera tripod at least. Holding it by hand will be very difficult except for the moon. Galileo didn't have a mount initially, but it will be much simpler if you have one.
To find an object one way is to remove the lens and sight along the body of the scope, looking through the scope until you notice the light coming from the object. Then put in your lowest power eyepiece first, centering the object before moving to barlow and higher power, if you wish.
Do not be disappointed if you don't see a great amount of color or detail in nighttime objects. Scopes of this size cannot do that. What you will get will be a great glimpse of what Galileo saw and how his genius is still with us today.
If you plan on getting this for a child, you will have to help them find the object they are looking for, as this can be very tricky for kids.
WARNING: NEVER POINT YOUR TELESCOPE AT THE SUN! NEVER!!!
Best and enjoy,
