Welcome!<br /><br />A Celestron 114 is a good scope to start with. Celestron are good optic, and you can see a lot of interesting things with a 114. What you will see will greatly depend on the quality of your night sky, though.<br />For planetary, no problem, you'll have access to all sorts of interesting things:<br />_You'll be abble to see mars as a tiny red disc, and on good nights you could be abble to see some of the biggest surface formations (in the form of darker areas).<br />_You'll have access to Saturn rings and the Cassini division, which is always quite spectacular (probably one of the most beautiful things you'll see, in a small or in a big telescope). You will also be abble to see one or two satellites, like Titan.<br />_ the most spectacular planet, to my mind, is Jupiter. First because it has the biggest apparent diameter in a scope, but also because it offers a great number of details even in a 114: cloud layers, great red spot, but also 4 satellites that change position from a day to another. You can also observe their transit in front of the planet and see their shadow reflected on the planet's clouds (quite a nice experience).<br />_you'll also have access to Venus phases, but no much other details;<br />_and of course, you'll have access to thousands of craters and formations on the moon (if you're interested in that you can get a moon atlas which will be very helpfull to find them).<br /><br />for deep sky, it depends as I said on thequality of your sky. If you can access naked eye to 5 magnitude stars, then it starts to be really interesting:<br />_first, there are a lot of double stars which are accessible even under poor skies, and which provide nice shows. Albireo, notably, is one of the most spectacular, because the two components show very strong and differenciated colors even in small telescopes.<br />_messier objects are all accessible to a 114. But not a lot of them will provide you great details. The most spectaculars in a small telescope are,
