Question 1- I keep seeing telescopes that say they have a refractor. What does that mean and should I get one that has it? Question 2- I had been looking for the best all around telescope that can see deeply into space, or that could at least as I had said, find particular stars. If it can see farther, does that mean it is better? And the farther it can see, does that mean that the quality of the view has a chance at being lower because of it? I will almost definitely end up getting one of the telescopes that you guys recommend because I am completely in the dark other than for the light that you nice people have shed for me on this subject.
