Amazon.com Review

Celestron's value priced PowerSeeker 60 is an affordable entry level telescope with some nice extras like a correct image prism and "The Sky" astronomy software included. The package also includes an Alt-Azimuth mount with adjustable aluminum tripod, high and low power eyepieces, a 3X barlow lens, and a 5 power cross hair finder scope.

The PowerSeeker 60AZ comes disassembled in a compact box, but the fully illustrated quick set-up guide makes it easy to assemble. Go ahead and try it out in the daytime, that's the best time to align the finder scope while looking at a distant tree or telephone pole.

The optics of the PowerSeeker 60AZ are surprisingly good, especially when I use the low power 20mm eyepiece. The correct image prism and the 20mm eyepiece give me a magnification of 35X, so backyard birds seem five times closer than with my seven power binoculars. My first view of Saturn's rings and globular cluster M13 in the constellation Hercules came with a 60mm telescope similar to the PowerSeeker 60, and the new PowerSeeker 60AZ is just as good showing me literally hundreds of craters on the Moon.

The PowerSeeker 60 can be upgraded with standard 1.25 inch telescope eyepieces. A 25mm plossl eyepiece for example gives a true field of view of almost 2 degrees for delightful views of star clusters like the Pleiades, while a 6mm eyepiece provides a magnification of 117X, just right to see the rings of Saturn or the cloud bands on Jupiter. The Alt-Azimuth mount included with the PowerSeeker 60AZ is lighter and easier to use than an Equatorial mount, but it does not track stars and planets. As soon as you get the Moon centered in the eyepiece it starts drifting toward the edge, this is caused by rotation of the Earth. The Moon may stay in the low power eyepiece for two or three minutes, but with the high power 4mm eyepiece (175X magnification) a star will disappear in only twenty or thirty seconds.

Celestron's PowerSeeker 60AZ is a real value because it has surprisingly good optics in a package that's light, portable and affordable. The drawback is that it has a lot of plastic parts, including the finder scope and the 3X barlow. For a more rugged alternative, take a look at Celestron's AstroMaster 70AZ which has more powerful optics, better eyepieces, and a much sturdier Alt-Azimuth mount. --Jeff Phillips

5.0 out of 5 stars Great starter telescope, October 14, 2004
This review is from: Celestron 21041 60mm PowerSeeker Telescope (Electronics)
I am pleasantly surprised by the telescope I got for the price. It was intended for casual observing and I am getting a lot of enjoyment out of it. It has all the accessories needed for viewing. High powered eyepiece, low powered eyepiece, adjustable tripod (stable for this size) and fine adjustment control for easy panning. I have shopped telescopes before and noticed that the tripods and eyepieces aren't too good in quality. But this one is different. I love the way it is easy to use for land viewing and gives nice views of the moon and its craters, specially when I use the high powered eyepiece. Its pretty lightweight so I can take it outside easily. It assembles easily and in my opinion is a very easy to use telescope. Overall, a nice telescope at a great price.

1.0 out of 5 stars Too Small, Poor Mount, Useless for Astronomy, August 18, 2005
By 
This review is from: Celestron 21041 60mm PowerSeeker Telescope (Electronics)
This scope is not a good starter scope for anyone interested in astronomy. Here's why:

1. The objective is too small, only 60 mm, 2.36 inches, so it is too small to bring in the light necessary for even a beginning look at the universe. I suppose it is adequate for the moon, but that is it. The planets will appear as very small disks. One will be able to see Saturn's rings, but the image will be very small. Forget it for deep sky objects, clusters, galaxies, etc.

2. The mount is an altazimuth, which will not follow the celestial object in the sky. The earth is rotating, and anyone focusing on a star or moon will quickly find the object drifting out of the field of vision. A better mount is an equatorial mount which makes it much easier to track objects.

3. The 4mm eyepiece is too powerful for this scope. The observer will find it hard to look through (very small eye opening), and will in most cases cause blurred images. The 20 mm eyepiece... Read more

1.0 out of 5 stars Stay away from this scope, December 30, 2006

Doug Rice (Twin Falls, ID USA) - See all my reviews
This review is from: Celestron 21041 60mm PowerSeeker Telescope (Electronics)
This is a good example of the kind of scope astronomers warn beginners away from.

The first red flag is the ridiculously high advertised magnification of "600x." Do you know what you will see at 600x in this scope? Nothing but a dim blur. Note that the objective (main) lens is 60mm. All telescope optics have inherent limitations; maximum useful magnification per millimeter of aperture is about 2x. Therefore, with any attempt to use this scope at magnification of over 120-140x, the increase in image size will be more than offset by breakdown, and that's even assuming the quality of the objective lens is any good.

The finder is useless; a 6x30 is barely adequate, and this is not even that big. Finding any object other than the moon will be an exercise in frustration. the 1 1/4" size of the eyepiece is creditable, but too high a mignification for this scope. And the field of view is in doubt, and don't even think of using the barlow. Buy this scope, and after a... Read more
