    Amazon.com Review
    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

    its an "alright" telescope3
    set up of the telescope is a breeze. the instructions were clear and also had pictures for reference. it took me about 10 minutes to get it together. i see people complaining the tripod is "unstable" NOT TRUE! its called tightening it! problem solved.
    the finder scope is made of plastic but hey, its not your main scope and look at what you paid for. the entire setup does feel cheap but think of it in terms of value.
    the entire weight is manageable, not portable but not very heavy.
    the direction adjustment knobs stick out way too far for what it does and it might get in your way if your not careful.
    now, lets get too the good stuff. WHAT CAN YOU SEE???
    my first target was the moon, it was clear and high detail, not a difficult task. i went onto jupiter, pretty much the brightest thing in the sky, you can barely make out the red and cream swirls it has and you can see bright spots around it which are the 6? moons. you cannot see jupiter up close even with double scopes (x20 normal plus the x3 add-on). the image isnt the clearest but hey, terms of value.
    if you are serious about getting into astronomy, move along with a different telescope. if you are looking for something to have some quick fun with friends and family, this is it.

    A Good Telescope 4
    Itis a wonderful product with minimum cost. I have tried to and have been able to see some spot in the Moon.
    Good product.

    A bit heavy and bulky4
    Celestron 21045 114mm Equatorial PowerSeeker Telescope

    On my deck this telescope is somewhat shaky,
    In a recent Readers Digest an article explained that ALL Telescopes are shaky to a point unless you set it up an solid ground, that took care of the shaky problem. Its hard to move everyday, with the tripod open its very difficult to get through a standard doorway, alot of work to get the legs folded up for every trip outside. the Optics is great, higher magnification is blurry but ALL telescopes do that...all in all? I say its a great star gazer!

  • Field of view at 1,000 yards: 298 feet

    Tech Talk
    Objective Lens: The diameter of the objective or front lens. The larger the objective lens, the more light that enters the binocular, and the brighter the image.

    Field of View (F.O.V.): The side-to-side measurement of the circular viewing field or subject area. It is defined by the width in feet or meters of the area visible at 1000 yards or meters. A wide angle binocular features a wide field of view and is better for following action. Generally, the higher the magnification, the narrower the field of view.

    Roof Prism System: In roof prism binoculars the prisms overlap closely, allowing the objective lenses to line up directly with the eyepiece. The result is a slim, stream-lined shape in which the lenses and prisms are in a straight line.

    Tech Talk

  • Magnification: Magnification is indicated by the first number given. For instance, "7x" means that you will see an object seven times closer than if you were viewing with the naked eye.
  • Objective Lens Diameter: The objective lens diameter is indicated by the second number (e.g., 21mm), which indicates how much light is able to enter the binocular. The larger this number is the better your sight will be in lower light conditions.
  • Roof Prisms: Roof prism binoculars are streamlined and compact because they utilize trim roof-shaped prisms to elongate the light path. Roof prism binoculars are usually more expensive than equivalent porro prism models.

    Good disposable emergency travel binoculars3
    Good disposable emergency travel binoculars

    I bought these binoculars to leave in my SUV as an emergency backup when I forget my excellent Nikon 7216 Action 8 X 40 Binoculars. They are much lighter and smaller and I can leave in my map holder on the door or even in my pocket and forget I even have them which leaves the old saying binoculars are only good if you have them with you. And that's where these binoculars shine they are very tiny and very light.

    They do bring things in close and after a little bit of focusing and adjusting width you can make things out if you have plenty of light. The little case they come with is pretty decent as well.

    Now for the bad parts. The eye relief is pretty bad, you will have to prop your eye glasses above them and or remove them to use. Also they are pretty dim which of course a lot of cheaper 10x25 binoculars are. The strap is a small little string that does the job but is pretty thin. But hey for the price go ahead and purchase a couple one for your coat pocket and one for your vehicle oh and maybe one for your camera bag.

    These would be a great pair to have children learn on as if they drop or abuse them its no big deal.

    Pros:

    Nice case
    Super small size
    Super light weight
    Disposable price tag
    Great learning binocular to hand to small children

    Cons:

    So so focusing
    Just Ok low light ability
    Just Ok optics
    Not water tight or resistant

    Verdict:

    Purchase as disposable emergency travel binoculars and or as a toy for children to learn birding with and no more.

    12-3-2008 Update:

    Went to the store and tested a lot of different small bincoulars trying to find a pair that are almost as good as my Nikon Action 7216 8x40's and found the perfect one. If you need small and want a good view and a good price get the Nikon 7508 Travelite 8 X 25mm V Binoculars. They are: light (8.9 oz), fit the hand well are well made and very bright in the viewfinder for their size.

    You get what you pay for?3
    For the price, it's difficult to find fault with these binoculars. Tasco is evidently trying hard to make a high-value product (not just a toy) at an extremely competitive price. They are light, small, reasonably solid, and for the price I never worry about taking them into situations where they might get a little wet or a little mechanical abuse (e.g., bumps or scrapes).

    So these would be a great choice for occasional or emergency use (e.g., to throw in a glove compartment or emergency bag, or to take hiking or backpacking), when having a small, lightweight, relatively high-power set of binoculars would be beneficial.

    If you'll be using these for extended periods of time, I would encourage you to keep looking. The eye relief isn't great, so if you wear glasses you won't be able to see the full field of view. Also, and it could just be my pair, mine do not focus very sharply (spherical aberration?), especially at larger distances.

    Also, be aware that these are probably best for active outdoors activities (hiking, hunting, etc.) in bright light -- if you can put up with the extra weight and cost, you might be better served by a pair with larger effective aperture and corresponding exit pupil (e.g., 10x42 or even 10x50) for pursuits like astronomy or (more sedentary) birding. This is not a criticism of these binoculars; they are designed to be 10x25, so the only thing I might complain about is the transmission of the AR coating, but that's simply not fair at this price point.

    If you do get a pair, do some thorough field testing as soon as you get them, and return them if they don't suit your expectations.

    Three stars may be too tough on these, but they're just not good enough optically to warrant more. Still, especially given their price, they're a whole lot better than nothing in a pinch.

    From the Manufacturer
    Nikon has updated its popular zoom binocular, the 8-24x25 Eagleview. This sleek, compact adventure binocular was designed to become a favored companion of knowledgeable travelers--whether theyÕre heading to the Rocky Mountains of Colorado, the beaches of the French Riviera or the wilds of the Peruvian Amazon. It's available in either black or silver.

    The 2005 Nikon 8-24x25 Eagleview Zoom model includes new ergonomic styling to allow a better, more comfortable grip on the dual-hinge polycarbonate body. Nikon has retained all of the user-friendly features that have made the Eagleview one of the most popular and versatile zoom binoculars on the planet:

  • Turn and slide rubber eyecups allow the user to quickly achieve the eye relief necessary for optimum viewing, with or without eyeglasses.
  • An exclusive, centrally located zoom control lever that enables the user to select any magnification from 8 power to 24 power with the push of a finger.
  • Bright, sharp Nikon multicoated lenses and high index BaK4 prisms provide true color rendition and crisp, clear viewing.

    Measuring just 4.7 x 4.3 inches and weighing only 12.5 ounces, the Eagleview Zoom is sized to fit in a coat pocket, purse or glove box. The binocular provides a 240 foot field of view at 1,000 yards when set on eight power, and possesses a 4.6 degree field of view at 8x, as well.

    Like all Nikon Binoculars, the Eagleview Zoom is covered by Nikon's 25-year limited warranty and No-Fault Repair/Replacement Policy.

    These things are AWESOME!!! I bought them for my best friend and she loves them. My dad wants a pair of them now. Will be getting him some for Christmas!!! Also, Amazon shipped them extremely fast!!!

    Very pleased!5
    Bought these for my husband for our anniversary, he is hard to please, very picky, but he was impressed with this purchase. He enjoyed using them at the football game. I like the compact size and the light weight.

    Very good product, but not for me4
    I purchased these glasses as a possible replacement for a larger pair of Nikon glasses because i hoped they would provide the same view in a smaller, more compact package. Unfortunately, I enjoyed the glasses but not enough improvement to supplant the older larger model. In short, the smaller package didn't provide enough improvement to make the change.
