Universe is simply infinite. And even the nearest planetary and star systems are at tremendous distance.
We just can’t get there for now. But then, at least we want to watch it. See it.
But I have seen people complaining “with a small telescope they can’t see much!”. And you too might agree on that.
And you know what? They are right! They will never be able to see more than what they try for.
This so-called beginner astronomers get discouraged, because they don’t get the results they expected.
Observing sky is not like spying your neighbors with binoculars. Its not that quick!
A good sky observer is also good in patience and is able to stare through the eyepiece for hours.
