Yes...if you're using KDE as your windows manager you should have KStars by default. It's a good program, and there are plenty of others you can find online as well. Have a look at this site...

If you're looking for a scope for later on, the best scope for a beginner is a 6-8" dob (dobsonian). That's a scope on a type of alt-az (altitude-azimuth) mount. Very easy to handle and in the size I mentioned quite portable. A 6-8" scope will give you plenty of light gathering capability and good resolution on objects. A scope like this will come with either one of two sizes of focuser...1.25" or 2". 1.25" is pretty much the standard size of focuser they fit to scopes, and this will handle the standard 1.25" eyepieces. A 2" focuser will handle 2" eyepieces, but can take the smaller ones with an insert for the smaller eyepieces added to the focuser. Also, the smaller eyepieces are cheaper than the 2" ones. Then you need to consider the size (focal length) of the eyepieces. You will need 2, at least, preferably 4 eyepieces. To give you a good spread of magnification, a set of 5/6mm, 9/10mm, 12mm, 15mm, 20mm, 26mm, 32mm and maybe a 40mm eyepieces would do. And a good x2 barlow thrown in to give some extra mag' choice. You can either buy them separately or in a set...which would be the best way for a beginner on a budget to buy them.
Bintel offer various eyepiece sets in good aluminium cases. Worth looking at. You can also get filters for visual observing that help enhance features of the planets by preferentially allowing different wavelengths of light to be observed. Most of the sets come with filters. One you will need, if the set doesn't have, is a neutral density filter. It polarises the light entering the eyepiece and cuts down on the glare. You'll need one for looking at the moon...in a 6-8" scope, looking at the moon without a filter can be rather startling and painful because it's just too bright. From there on, whatever you add to your equipment collection is bonus.
I needn't remind you of the danger of looking at the Sun through a scope. The only way to safely do that is to stop down the scope (reduce its aperture...with a mask) and use a mylar filter for the size of your scope. But that is if you want to go in that direction.
Hope that has helped
