Digital Cameras Photo Reviews of Celestron 21045 114mm Equatorial PowerSeeker TelescopeCustomer Review: Very good telescope for the money. Summary: 5 Stars
I must admit that this is my first telescope, but I did play with other telescopes and spotting scopes before.
What other people say about it is true: the mount is shaky, and this is an issue for high magnification modes (more than x45). In fact, even a light wind will cause it to move.
The manual is also very basic, doesn't describe much at all.
However, putting it together is very easy, and shouldn't take more than 30 minutes. The instructions are easy to follow, but you might need some help from another person when you mount it for the first time.
The only thing I really don't like is how heavy and big it is, especially with the tripod extended. If you plan to bring it in every night after you are done with it, then consider the fact that you will need to 'unextend' the tripod, which is hard to do because it is heavy and big. I wish there was an easier way to extend the tripod, without screws.
On the other hand, I got it for less than $150, including shipping, so I can't complain.
The image quality is excellent, and it can be very well used for ground observations, although the image is upside down, and the mount is not really meant for ground observation (EQ mount).
For example, there is a radio relay about 1 mile away, and with the naked eye you can't see much of it. However, with full magnification (675 times) you can see the lighbulb on top of it as if you were just a few meters away. Such high magnification comes with the downside that the image is very dim.
Overall, this is a very nice telescope to have as a hobby, but if you want something better (computerized mount, higher magnification, etc.) then you will have to spend over $500

Celestron PowerSeeker 114EQ 45X-225X Reflector Telescope I love bargains, so I was eager to try out Celestron's new Powerseeker 114 Newtonian reflector telescope. With its 4.5-inch mirror, Celestron's Powerseeker 114 gathers three times more starlight than popular 60mm refractors. The Powerseeker package includes two eyepieces (K20 and SR4), a plastic 3x barlow, and a lightweight equatorial mount. Optically, the Powerseeker 114 holds its own when compared with my Celestron Firstscope 114EQ. Using the K20 eyepiece included as standard equipment, about 45x magnification, it's easy to see the Andromeda Galaxy and its smaller satellite galaxy M32. When compared to 60mm refractors, the Powerseeker 114 brings out much more detail in the Orion Nebula, reveals many more stars in Perseus' Double Cluster and even brings out a few individual stars in globular clusters like M13. Saturn looks quite small at 45x with the K20 eyepiece, but using my own 7.5mm eyepiece (120x) I can easily detect the shadow cast by the planet on the rings, and even glimpse the ring's Cassini Division. When the mirrors are properly lined up or "collimated," the images are reasonably sharp up to magnifications of 225x. I find a collimation tool helps get this fine tuning just right. As good as the optics are, however, the effect of cost-cutting shows up in the mechanical components. The focuser is plastic, the finder scope is plastic, the rings that attach the telescope to the tripod are plastic. Even when the tripod legs are clamped at their shortest setting, the telescope wobbles when I try to focus at higher magnifications. Celestron's instruction manual correctly recommends that most viewing be done in the range of 40x to 130x. So what about that 675x magnification proclaimed on the box? I'd say it's not worth the trouble. Overall, the Celestron Powerseeker 114 is a budget priced telescope with good optical performance, especially when using the low power K20 eyepiece. If you're willing to spend a little more money, either Orion's SkyQuest XT4.5 or Celestron's Firstscope 114EQ will give you a sturdier mount, an improved finder scope, and better eyepieces. Also, for about the price of the Powerseeker 114, I like the dependable refractor design of Celestron's Firstscope 70EQ. --Jeff Phillips Pros: - Low cost
- Good optics
- Serviceable K20 eyepiece
Cons: - Wobbly mount
- Difficult to collimate
- Plastic finder and focuser
