Have a nice time i find Meade ETX-80AT-TC Achromatic Refractor Telescope - Silver (0805-04-21) I will think This Interesting ,and you can see that
BuZZ from Customer Shopping
It's NOT the Hubble...but for under $300, really delivers.
If you take the time to calibrate the motors, train the drives, and lay it level, point to true North, it does go to objects asked for.
And if you use the high precision mode, it references to a proximal known point, then slews accurately to the asked-for object. A final caveat - use lower power for searches, then up the power. Optics are crisp for this price point.
Poor way to allocate your telescope dollars
This scope seems to have, on the surface, a lot to recommend it- decent optics, computer guidance, etc., and to the novice amateur astronomer, it looks like a pretty good deal. Meade's pushing it as a slightly smaller version fo their very popular ETX90- but is it?
The ETX 90 is a long-focus Maksutov-Cassegrain- their attempt to clone the Questar at a fraction of the cost. The ETX doesn't really compare to the Questar (not surprising, as Questar spends more on the optics than the ETX costs!) but it's still pretty good for the money. An ETX90 can deliver sharp images up to perhaps 200x under ideal conditions.
The ETX80, though, is a very different animal. It's a short-focus 80mm refractor- sort of like half of a pair of binoculars- on a computer drive. And a short focus scope of this size is really only good up to about 40x magnification before secondary color starts blurring the image. Yes, you can see the rings of Saturn, but a decent pair of 7x50 binoculars will show you that as well.
The computer guide is less useful than it might seem; it takes time to set up and align and is really not needed on such a low powered telescope. You don't need a computer to find the moon, the larger planets or the brighter objects that this scope is capable of seeing. What you have, in essence, is a $150 telescope on a $150 computerized mount. In that price range, it's silly to spend half your budget on automation.
If you have $300 for a telescope, Amazon also sells Orion Dobsonian reflectors in various sizes that have far more light gathering ability and can see much dimmer objects. They're also steady as a rock. They may not have the same high-tech coolness factor, but they never need batteries, and for the typical beginner they're a much better choice.
Awesome performance for the price
First off, buyers must be aware that this is only an 80mm refractor and will not blow you away with its deep sky ability. That being said, this scope is a perfect starter scope for lunar and planetary exploration.
I was pleasantly surprised with the go-to unit found on the ETX-80. Easy alignment with an option to park the scope back at home position so that if you set up the telescope in the same place everytime, you don't have to align near as often.
Observing with the scope was very easy as my target was in the eyepiece field (26mm) all of the time. Saturn's rings were fully visible with the 9.7mm eyepiece as were Jupiter and her 4 largest moons. With clear viewing, cloud bands are even visible on Jupiter.
The only drawback I have found is that with the 9.7mm + barlow combination (82X magnification) it becomes very difficult to fine focus in on Jupiter. The focus knob is a little unwieldy and shakes the telescope when "dialing in". A more stable tripod and a different focuser would make this a 5 star item.

Product Description
The compact and portable design of the ETX-80AT-TC Refractor Go-To Telescope will have you out observing the inexhaustible quantity of visible phenomena in no time. The ETX-80AT-TC double-tine, fork mountings include high-torque DC motors on both telescope axes, permitting electronic operation from the included plug-in AutoStar hand controller. You can instantly select any speeds simply by pressing the SPEED button on the AutoStar controller. As an added bonus, the ETX-80AT-TC telescope comes with Meade's ultra-sturdy, easy-to-use, Standard Field Meade #882 Tripod that features micrometric controls to provide precise equatorial alignment of your telescope at any observing latitude from 20 to 90 degrees. This alignment is useful for fully automatic tracking of celestial objects in right ascension. Should you decide to look at the surface of your own planet for a while, the Altazimuth (90-degree) Orientation option provided by this tripod is useful for terrestrial viewing. This is also the preferred mode for astronomical applications when you use the AutoStar controller for automatic object location and tracking.
