Product Description
Without spending a fortune you can get a telescope that will not only satisfy the kids, but the kid in you! Our SkyQuest XT4.5 is a quality telescope, with point-and-view simplicity that makes it easy to use and makes stargazing fun! The optical performance is far and away better than flimsy department store models. Its 4.5" (114mm) mirror, housed in an enameled steel tube, gathers 260% more starlight than a 60mm refractor. More light means you can see a lot more celestial objects in greater detail. In a review of beginner telescopes under $200, Sky & Telescope (12/05) proclaimed the XT4.5 "The best of the bunch - a solid combination of optics and mechanics." Try it and see for yourself!

Amazon.com Review
Orion's Skyquest XT4.5 is the smallest in their Dobsonian line of telescopes that includes the B00020WZB0 XT6 , XT8 , and XT10. Newcomers to the hobby are always surprised at how large amateur telescopes are, but to experienced observers, this XT4.5 is considered a very small scope. Tiny, in fact (It's so small, astronomers are buying them just because they think they're so cute). Make no mistake, though--the XT4.5 is a full-fledged telescope, and is a serious observing tool that could last you for years.

Your money buys you a lot in this case. Included are a good-quality 4.5" f/8 primary mirror, two eyepieces, a finder, and a CD-ROM with a stripped-down version of The Sky, a software guide to the sky. The scope comes in two cartons. One contains the optical tube, and the other is a flat-packed box containing the base, which you assemble yourself. Orion includes all the hardware and tools you need, and the instructions are well written. Allocate about 30 minutes to assemble and align everything.

the XT4.5's features
There are a couple of cost-cutting measures. The primary mirror is spherical, not parabolic (this is not likely to affect the views, however). Also, the focuser is plastic. While I've never seen one break, plastic focusers are by nature less robust than metal ones. Finally (and this may be the most serious concern of all), the scope is a little short for an adult. The eyepiece is only 3 feet off the ground, which may force you to stoop over (hint: try sitting on a short chair or stool while observing). On the other hand, the height is ideal for a child, and as a result, I heartily recommend this telescope for children.

Under the stars, the XT4.5 exhibits excellent performance. Once properly collimated (aligned), the optics give clear, sharp, contrasty views. I've spent enjoyable nights using these telescopes, both as a teaching tool and by myself. Jupiter's cloud band and four moons are no problem to see, nor are Saturn's rings. The Orion Nebula is a glowing fan of green gas, with a quartet of tiny stars at its core. Under dark skies (and with some diligence) the XT4.5 can even pull in some of the fainter deep sky objects, like the brighter galaxies in the Virgo Cluster.

Despite the fact that I have a garage full of expensive telescopes, I never feel compromised with any of Orion's XT scopes. As recently as a few years ago, the old adage regarding telescopes was that you must spend at least $300 to avoid buying junk. While this is still mostly true, Orion's little XT4.5 breaks the price barrier in a big way. As long as you can deal with the short eyepiece height, it's a great starter scope.

Pros:

  • Very good optical and mechanical performance
  • Fully accessorized
  • Great value
Cons
  • Short eyepiece height
  • Plastic focuser

4 out of 5 stars nice, small telescope   August 12, 2008

Well, first of all, I think most of these "reviews" are fake. I don't like that at all.

This is a fine, small telescope which can show you planets like Jupiter and Saturn. It gives very faint views of messier objects, like open clusters. You need good eyes to see those.

When it arrived in the mail, I was baffled by all the parts, which didn't look like the parts in the pictures. A skilled carpenter assembled it for me, and he had to use several tools, which I wouldn't have known how to use. So, assembly is complicated.

I now use the telescope every night. I have been looking at the Double Cluster in Perseus recently. The weight is good and makes it very moveable. I am considering getting a larger scope in this series, because the 4.5 inch mirror is small.

I am new to astronomy, and this was my first telescope. It was easy to assembly, and I have been enjoying it very much. I can now see the 4 moons of Jupiter, and the rings around Saturn, and to view the moon is totally awesome. This is a great beginner scope at a reasonable price!

This is a great scope for beginning astronomy--and beyond. It is sturdy and simple to operate. It has enough light-gathering power (more important than magnification) to reveal dim star clusters, nebulae, and galaxies and good enough optics to show you the surface of planets like Jupiter, Saturn, and Mars. Affordable as this scope is, there is no reason to give so much as a glance at the trashy 60mm refractors with exaggerated magnification claims that litter the market.

Some advice on selection. Dobsonians come in a range of sizes; the bigger the instrument, the more you will see. A long-focus 114mm (4 ") like this one is a fine instrument, especially for children and others whose ability to carry large objects is limited. A teen or able-bodied adult should consider going up to a 150-200mm (6-8") scope. Bigger Dobsonians (250-300mm and above) are too heavy and bulky for some people.

Some advice on use. Viewing through a telescope is less like playing a CD and more like playing a guitar. Finding objects takes a little bit of practice. To simplify it, I would suggest supplementing the finder supplied with this scope with a "red-dot" finder to aid in initial pointing. You will also need to buy a star atlas (Sky & Telescope's Pocket Sky Atlas is the best available), a red flashlight to read it without blowing out your badly-needed night vision, and a guidebook to lead you to interesting objects. These investments will greatly add to your enjoyment.

What more can I say? This is the kind of scope that experienced observers have been trying to steer novices towards for decades. Although, I recommend that you do your homework before buying any scope--learn the sky and get to know experienced stargazers who can advise you--when it comes time to purchase, this scope is a fine choice.

For more advice, see my encyclopedic guide here on Amazon, "So you want to buy a telescope."



5 out of 5 stars Great telescope for kids and adults   October 4, 2006

We received the SkyQuest XT 4.5 about two weeks ago and we absolutely love it. My six year old daughter and I opened the two boxes, put it together, and within 15 minutes we were out in front of our house looking at the moon, start clusters, the moons and cloud bands of Jupiter, and the Andromeda Galaxy. It is big enough to see all of these things from a big city yet it is small enough to easily fit in a closet.

If you are looking for a light weight scope you can pull out of the closet on a whim, big enough to see the items mentioned above, and easy enough for a kid to use, this is the one.
