well that is what happens with a cheap scope and mountlong time ago I had small telescope with max 40x magnification but I was not satisfied by it, mainly because it was very unstable where the least wind causes shaking and everything I see through it was very blurry including nearby planets like Mars and Venus.
Quality cost money
again I aim you at the thread V50 posted where all this is discussed
So, what sort of budget do you have ? and keep in mind that something stable is going to cost
~ US$500 and up. Buying something less that ~ US$500 is going to give you all the same problems
that you had with that first scope
