Never use a Newtonian telescope (Or 'Catadioptric Newtonian') with a spherical mirror under f10 These telescopes are an exercise in cost cuting and give awful image quality. The primary mirror is not parabolic and so CANNOT bring all the light to the same focus. No matter what you do the image will always be a little blurred and unsharp. Also, the Barlow lens in the draw-tube is supposed to 'help' with this problem, but only magnifies the error in the main mirror. The Barlow also makes collimating the telescope almost impossible! Awful instruments - Avoid them. AVOID any telescope with a spherical (Non-parabolic) mirror and avoid all telescopes with a built in Barlow. These typically have a total length of about half the focal length stated... So, I you have a Newtonian that says 1,000mm focal length and the tube is about 500mm long - Bin it! Get yourself a Parabolic Newtonian, without the Barlow (Typically the tube will be the same length as the focal length). You will have much much better images and setting it up will be easier and more accurate too!Read full review

Great telescope for the price. Images of the moon are amazing. I do stay in a area with no light pollution though.

A lot off slack in the lense slides/ adjustment. poor set-up instructions/ adjustment in sight scope. Have managed to see moon despite above, but clouds etc so could not assess lense fully yet.
