Celestron 21041 60mm PowerSeeker Telescope
Celestron 21041 60mm PowerSeeker Telescope
Celestron's value priced Powerseeker 60 telescope takes a basic "just the facts" approach to affordable entry level telescopes. The package includes an adjustable aluminum tripod with an alt-azimuth mount and stabilizer, a Kellner type K20 eyepiece, a Ramsden type SR4 eyepiece, a 3x barlow lens, and a 5 power cross-hair finder scope.
The Powerseeker 60 comes disassembled in a compact box, but it won't take long to put everything together. 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.
My first view of Saturn's rings and star cluster M13 in Hercules came with a 60mm telescope, and I enjoy celestial viewing with the Powerseeker 60 to this day. The secret is to use the low power K20 eyepiece and only extend the tripod legs half-way. This gives me sharp and steady views, whether I'm looking at nearby hills, craters on the Moon, the Double Cluster in Perseus, or even the Andromeda Galaxy!
With a 1.25" focuser and diagonal mirror, it's easy to add better eyepieces. The Kellner type K20 eyepiece yields a 1.1 degree true field of view, better than the Huygens or H-type eyepieces still found in many beginner scopes. Adding an optional Celestron 25mm E-Lux eyepiece is better still. With nearly 2 degrees true field of view, the 25mm E-lux makes it much easier to find objects, either on land or in deep space. The SR4 eyepiece is less impressive; it's like peeking through a pin-hole. Adding the 3x barlow to the SR4 to get that 525x proclaimed on the box is peeking through a dim, fuzzy pin-hole.
I'm surprised that a telescope this inexpensive can be this good. It's good enough to show me Saturn's rings at night or a Steller's Jay at 100 yards during the day. In my opinion, the Powerseeker 60 would be an even better bargain if it came with a K10 eyepiece in place of the 3x barlow and the SR4 eyepiece. Also take a look at Celestron's Firstscope 60AZ; it's only a little more expensive, but it includes two useable eyepieces, a red-dot finder, and planetarium software for your computer. -Jeff Phillips
