As the listing advises, this telescope should be considered a beginner and/or kids telescope. The 300mm focal length is the minimum to be considered for astronomical uses. Despite this, the scope does a respectable job of magnifying the moon, and terrestrial (earth) objects. I have not yet tried it on other celestial objects.This kit has everything that a beginner would need in a scope, and more. It comes with the telescope, a finder scope, a tripod, a diagonal mirror, three eyepieces, a 3X Barlow lens, an erecting eyepiece, a moon filter, a mobile phone holder, and a carrying case. The mobile phone holder should be a real plus, since many folks want to take pictures through the scope, which this allows. Unfortunately, it did not work for me. More on that later. A great inclusion in this kit is the case. Since this is a compact telescope, the case allows for convenient storage of all components and even has extra room for other things that you might want to carry when out on an excursion to view the stars.Assembly of the scope is easy. Screw the scope to the tripod, install the diagonal mirror, install the desired eyepiece and you are ready to go. If you want an easier way to align the scope onto objects, then you will want to install the finder scope. This is a mini-scope that allows you to better align the main scope onto your object. It is often difficult to get properly aligned, so I always use the finder scope.The nature of this, and many other telescopes, is that the image is backward when viewed through the eyepiece. An example of this is if you are looking at a sign, the wording will be backward. This is not necessarily a problem when looking at a celestial object, but it can be confusing if viewing a terrestrial object. Fortunately, the kit includes an erecting eyepiece that corrects the image.The three eyepieces come in different magnifications and the Barlow lens further magnifies the images, as does the erecting eyepiece. Depending on the lens selection, the magnification ranges from 15x to 150x, which is a significant range.The included mobile phone mount did not work at all for me. When attached, it did not stay in position. Nothing that I did would keep it in place. I suggest that you do not use it unless you have an old phone or one that has a great protective case in the event that it falls to the ground. I did not knock any stars off this scope because of this, since the rest of the telescope works great.
