First advice: make sure your mount and tripod are rock solid. Many beginners go off astronomy because the telescope is wobbly and they can't see anything with it. A word of caution; I noticed you wrote "675X4.5 inch". I presume this means the company claims you can magnify up to 675 times. First of all, magnification is the *least* important attribute of a telescope. The size and quality of the primary mirror, a good collimation, sturdy mount are the things you should look for. Second, the rule of thumb in astronomy is a *maximum* of 50X per inch of mirror. In your case, this translates to 225X. Anything beyond that will give you mediocre, distorted images. I hope this helps. Enjoy exploring the nightsky.
