    This was my first telescope and I think it is good for beginners and kids. It is good for the price that it is. I use it in my suburban backyard where there is significant light pollution. Pros: -Fast shipping, scope came two days after ordering, all contents was packaged nicely. -With this telescope you can see: 2 clouds bands and 4 moons of jupiter, ring of saturn, orion nebula, craters on the moon... -Stable tripod, no shaking or vibrations. -Finder scope is good quality. (But flips image upside down). -All lenses good for terrestrial / daytime use. -Slow motion control for tilting works well. Cons: -View suffers from minor chromatic abbreviation around moon and planets. -The Barlow lens must be used before the diagonal to work. (Makes changing magnification difficult). -Barlow lens used with the 4mm eyepiece is useless at night. It does not focus at all. -The tilting mechanism is finicky, but you get used to how to control it. My only real complaint is that the Barlow doesn't work better. I would recommend this scope to anyone interested in amateur astronomy.
