Good for starters
This is good to use at night or daytime, a plus. It's easy to put together and easy to change out the eyepieces lenses. Cons are that after you line up a planet with the view finder, it's very hard to get it in the telescope itself. The 'arm' that moves the barrel of the telescope is stiff, sticky, and moves too fast in any direction to help you locate the planet in the eyepiece. It's well constructed but because of its size, it is difficult to store -- my cats have tipped it over and done some damage, so this is my second unit.

Great Scope
Was looking for something to assist in teaching the kids about the universe and this was a great find. This 90 AZ can allow you to see so many more things in detail than other smaller scopes. My kids love it and beg me to take them to the country away from the lights as often as we can!
