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

I should add that the telescope had probably traveled a few miles around the globe when it got to me, but the box and packaging were in pretty good shape when it arrived.
When I got it, I initially compared it to another $50 reflector, the Celestron 76 mm Discovery, and the results were very disappointing, the smaller one was much sharper. I spent hours reading on the Celestron and other sites on how to adjust collimation with a simple "hole in the cap" and got nowhere. The image was always relatively blurry. Day or night, polaris or no polaris.
I later bought the Celestron 24mm to 8mm zoom eyepiece, which allows me to zoom in without changing eyepiece, and it works very well on the smaller 76mm telescope, but again blurry images on this one.
After quickly becoming an expert on reflector collimation, I noticed that nothing seemed collimated properly. I guess they don't even try at the factory on this one? I decided to order a Celestron 1.25" collimation eyepiece ($30), which can be useful in aligning the optics (the two mirrors) in reflectors like this one. I tried it out on this one, and got repeatedly confused on what should be seen in what reflection when you adjust this or that. I spent entire afternoons fiddling with secondary versus primary mirror adjustments, achieving virtually nothing as far as improved sharpness is concerned.Read more ›
Let me say from the start that I'm a refractor man and proud of it! I've always found chromatic aberration a minimal disturbance compared to the sharpness of resulting image due to a clean unobstructed tube of light. (and, yes, I know about and use off-axis aperture stops on my reflectors when higher magnification, but they are only practical with 8" mirrors or larger.) Refractors are virtually maintenance-free and, except for rare occasions, the tube remains completely sealed (i.e. nothing can fall in). I still have two old 8" and 13" Coulter Odysseys that I take out occasionally, but I've always found them awkward to use and move around and the views not all that satisfying despite their greater light gathering power (a slightly overrated attribute).
I have two large refractors (a 6" Celestron and a 4" Tal) that I use and love, but they weight a ton and hard difficult to haul around. The Celestron takes at least 15 minutes or more (depending where you are) to set up properly. For several years, I've been looking for an inexpensive, lightweight scope with good optics I could keep fully loaded and assembled that I could quickly and easily take outside and start viewing.
Several years ago I picked up a 90mm Meade refractor which was so overall terrible I didn't think the scope I wanted even existed. In November, I came across the Celestron 70 AZ Powerseeker for a super low price and sent to a young but sharp cousin of mine. I got such a favorable report, I decided to gamble on one for myself.Read more ›
As for assembly I have noticed some reviews for this product stating it was difficult to assemble and parts were missing and/or broken. I must say I was fortunate not to run into any of these problems. I was able to assemble everything in about 20 minutes and this is my first experience with an equatorial mount. everything fit together logically and I didn't require a manual to put it together. It was a case of open the box containing the next part,look at the picture on the box, and slap it on and move to the next piece and so on. Once assembled it took about another 10 minutes to balance the scope on the mount. This I used the manual for since as I mentioned before I have never used an equatorial mount. The Manual could have been a little more detailed for a beginner like me, but it wasn't exactly tedious either. Performing the Polar Alignment was a snap. The Hardest part was trying to find something to keep me occupied while I waited for the sky to get dark.
Navigating the sky using the included software was easy and straight forward. My wife and I were able to navigate to the moon, mars, and Saturn very easily.Read more ›
