Lots of reviews already for this, and I won't bother with a ton of details. For the money, it's the best scope I've used, ever. It's not perfect, but for my 8 year old son, it's a wonder.
Easy set up, light, very portable, excellent images. Excellent brightness of even faint, distant objects. This thing really does produce very bright, vivid images. Moons of Jupiter? You bet. Bands of Saturn? Sure, under ideal viewing conditions. And the moon, wow. Super crisp and vivid - and you do need the moon filter for that, it really should be included (mentioned as a CON, below). Color is really great, too...there's enough light gathered that colors are surprisingly distinct. I'm having a lot of fun with it, and my boy is, too - again, very good viewing for the money.
Breathing hard on the thing, much less working the focuser roughly, will throw you off target. Steady hands, go slowly, light touches. The tripod is adequate, but even the slightest wobble or position shift will require re-finding your target. As long as the tripod is on a solid base (concrete, firm deck, whatever), it's fine. In the grass? Not so good.
The spotting scope is not completely useless, but close. If you're very precise lining up the dots, and holding your head steady, and have perfect vision, it WILL get a single star somewhere in the viewing field. Larger objects are easier to find. But be prepared to spend 5 minutes fussing with it every time you change your target. Still, it gets the job done if you're very careful and precise with it.
There's quite a bit of play in the adjustment knobs, so fine tuning something into the center of the field takes a steady hand. Treat the knobs as you would a kitchen timer or barbecue grill flame knob, and you'll do better. Turn a knob a bit past your desired position until you take up the "slack", then turn back the direction you want to go while there's good tension on the knob. Works much better that way.
With a DSLR attached to the optional camera mount, you get very impressive photos...but again, you need a very steady hand. I use the remote to snap the shutter, because just touching the camera body to press the shutter button can throw my image off.
The moon filter is necessary, really, but you have to buy it separately [Celestron Telescope Moon Filter - 1-1/4" 94119-A].
