Celestron 21049 PowerSeeker 127EQ Reflector Telescope, Black

A special birthday gift. Seems of good quality, son says it was quite easy to assemble, and looks very good. He recommends purchasing a separate filter as there is some glare when looking through at the moon. But was thrilled to receive it.

Really good. Just effort to get it out of the spare room init

This is a great entry level telescope, is good value for money, and easy to use once you have set it up but!!! The set up guide is pretty much useless and feels as though it is written by a geek who, being expert in their subject, is to busy and important to disseminate the information required to mere mortals who are unworthy of his attention. The manual provided is written in German, which is great for German speaking people, not so much for anyone else and he registration process is best undertaken from Microsoft laptop, because it won't work on a Mac and neither will the software that accompanies the product. Also, there is no UK support number, so you're pretty much restricted to email. This is the only reason I have rated this product as a four star rather than five which the product certainly is. Technical details about the product:- The Celestron PowerSeeker 127 is a 5” equatorial reflector with enough aperture to show you clear views of the brighter star clusters, nebulas, and galaxies. Its Newtonian reflector optics give you detailed and sharp views of the Moon and planets, as well – without the faint purple haze of chromatic aberration (spurious colour) that surrounds every bright object in every refractor scope in this price range. And this Celestron telescope does it at a price that’s shockingly reasonable for this size telescope. The construction of the optical system is first rate, as the Celestron PowerSeeker has all-glass optical components, with high reflectivity aluminium mirror coatings for enhanced image brightness and clarity. The equatorial mount has slow motion controls in both axes, to let you easily track objects across the sky. The Celestron PowerSeeker 127 has a light grasp 329 times that of the sharpest eye. Combine that light grasp with its two eyepieces (a 20mm and a 4mm) and 3x Barlow lens, and you have the ability to see many, many celestial sights that are simply invisible to the unaided eye. It can open a whole new world to you, at a surprisingly affordable price. This Telescope’s Optical System . . . Reflector optical tube: 127mm (5”) aperture Newtonian reflector with all-glass mirrors. Each mirror is coated with highly reflective aluminium and over-coated with quartz for long life. No plastic mirrors. 1000mm focal length aluminium tube with protective tube end rings. f/8 focal ratio. The reflector design of the scope is totally free of the purple haze of spurious colour visible around the Moon and planets in lesser refractor scopes. Images are sharp and clear. You can even collimate (align) the mirrors for the sharpest images. This will have to be done only rarely, thanks to the special design of the cell holding the lightweight mirror. Rack and pinion focuser: The 1.25” focuser has dual focusing knobs for precise image control with either hand. The large focus knobs are easy to operate, even while wearing gloves or mittens in cold weather. Two eyepieces: You get a high power 1.25” 4mm (250x) eyepiece and a low power 1.25” 20mm (50x) with a 0.9° field of view (nearly twice the diameter of the full Moon). Both eyepieces have antireflection coatings on their lens surfaces for sharp images and good contrast. The 4mm eyepiece is right at the scope’s usable magnification limit on the rare nights of very good seeing conditions. An optional 6mm or 7mm eyepiece comes closer to providing the highest useful power on a night in/night out basis. Barlow lens: A 1.25” 3x Barlow lens is included that triples the magnification of the two supplied eyepieces to 150x and 750x. The 150x of the Barlow and 20mm eyepiece combination will be the useful maximum power on those nights of average to so-so seeing conditions. The 750x magnification of the 4mm eyepiece/Barlow combination is realistically substantially beyond the scope’s usable magnification capability, however. Do not count on using that optical combination very often, if at all. A lower power eyepiece, such as a 40mm (25x; 75x with the Barlow), would provide a pair of magnifications more useful than the impractical 750x of the 4mm and Barlow combination. Finderscope: A low power 5x24mm Finderscope attaches to the side of the optical tube. The straight-through viewing refractor Finderscope provides a traditional inverted mirror-image astronomical view. If properly collimated (aligned) with the view through the main telescope, its crosshairs will help you centre distant objects in the telescope so you don’t have to search for them using the narrow eyepiece field of view. This Telescope’s Mount . . . Equatorial mount: The equatorial mount is designed for astronomical observing. By aligning the mount on the north celestial pole, you only need to turn one slow motion control knob to follow planets and stars as they travel across the sky. A counterweight on the opposite side of the mount from the telescope balances the weight of the optical tube and makes it easy to move the scope effortlessly from one part of the sky to another. Setting circles: Setting circles (graduated scales marked in either hours and minutes or degrees) are provided in both right ascension (the east/west position of objects in the sky measured in hours and minutes) and declination (the north/south position measured in degrees). These allow you to align the scope on the approximate position of an object in the sky by using its RA. and DEC coordinates from a star chart – before you search for it in the Finderscope and eyepiece. Setting circles can reduce the time it takes for you to find the fainter and more difficult deep space objects. Manual slow motion controls: There are two slow motion control knobs connected to the mount by long flexible cables so they are easy to reach while observing. One controls the scope’s motion in right ascension (the east/west direction in the sky). Turning this knob enables you to follow the motion of celestial objects as they travel from east to west across the sky. The second controls the scope’s motion in declination (the north/south direction in the sky). Turning this knob enables you to correct for any north/south drift a celestial object may take as it drifts across the sky, due to an improper alignment of the scope on the north celestial pole when you first set it up. The two controls combine to give you complete access to any part of the sky. They give you the ability to star hop from a known object to an any other object by using a star chart. They let you centre objects in the field of view, and track them effortlessly with only an occasional quick turn of the RA. knob. Tripod: The lightweight aluminium tripod easily adjusts for standing or seated observations through the telescope. The tripod includes an accessory shelf that holds your eyepieces and Barlow. Software: A copy of Celestron’s TheSky X – First Light Edition CD-ROM is included for use in your PC or Macintosh. This planetarium and star charting software will let explore the Universe on your computer. It can print out custom star charts of the sky from its 10,000 object database to help you find faint deep space objects by star-hopping in easy steps from a known star to the object. Two year warranty: As an expression of Celestron’s confidence in the quality of their products, the PowerSeeker is protected by Celestron’s two-year limited warranty against flaws in materials and workmanship. HOW TO SET UP YOUR SCOPE: We found that the best information is located on, wait for it... YouTube! There are a number of videos from people showing how to set the Powerseeker 127EQ up, who obviously had the same difficulties that we did. Additionally we found a great community of Astronomers who have posted great videos about how to set up and use telescopes with equatorial mounts! In short, we have now got to grips with this scope and are pleased with it. It is however let down by very poor documentation, guides in the wrong language and software that only seems to want to work with Microsoft!

This is probably the best Beginner's Telescope you can buy. At under £120 it is incredible value for a metal telescope tube, tripod and EQ mount. The accessories are OK, but the 3x Barlow lens is very poor and should be thrown away. Excellent for viewing the Moon and Double Stars. Good for viewing the Planets and Bright Comets. OK for viewing Bright Galaxies and Bright Nebulae.

This is not an easy telescope to set up. Nor is it without its faults: The main cap is loose, a poor fit, and falls off easily. The eye piece focus unit exposes greasy parts and soon your hands are coated in grease. The finder scope is impossible to setup with any type of repeatability and is flimsy. It is also too close to the main tube to easily use and doesn't have a rubber sleave for those wearing glasses. My telescope arrived with a smear on the lens in the focusing unit. Luckily it was on the underside. There's no apparent way to easily clean the upper side. It took 3 hours to set up. I had to dismantle and refit the secondary mirror along with its supports. I still have a blur somewhere in the telescope I can't fix. I feel the optics are cheap. You will need to buy a collinator and know how to use it. Extra tools are needed to set up. I had to use my own spanners to tighten the loose bolts on the mount's main worm screw and I needed to add a M12 washer on one bolt to get a tight fit. Your own philips screwdriver is a must. The planet trackers are ok but only one is a worm screw so the other can run out. I do have experience with mechanics, have a workshop, and a degree in astrophysics so perhaps it's less bother for me than might be for someone else. As a city dweller I rate it OK for moon photos but IMHO it's a waste of money if you have poor "seeing" in your area. After several days of effort I was able to take this photo of the moon using the supplied 20mm sight (supllied) and a mount (not supplied) for my mobile phone. One final point: the entire system vibrates quite badly. Even a minor adjustment requires time for it to settle. I'll probably keep it but I will make my own finders scope mount and replace the finder scope with something better. For ~£200-300 your getting exactly what it's worth. Expect to spend more money and time to get something better out of it.

where to start? i'm a beginner to astronomy and this seemed too good a deal to pass up comparing to similar priced entry level scopes. pros: looks amazing, easy to set up once i got past the issues listed below. cons: my package had the mounting bolt missing. amazon refunded me 15 quid as compensation - no replacement offered upon inspection the equatorial mount bracket for the telescope was 90 degrees off. the side to side movement only goes one way lining up the search scope to the actual telescope lens is a nightmare to get right - still havent it spot on which makes it really difficult to dial in the scope to view stars definitely not for beginners

Nice and in good condition received. But i am suggesting that take with motor set Which focus automatically

جا فكرتون مرتب ماشاء الله وسهل التركيب طريقة استخدامه فيه مقاطع كثيره باليوتيوب لطريقه التكريب والاستخدام شكرا على سرعة التوصيل

三脚もしっかりしていて安定は良かった。まだ、月の観察のみですが土星を観察するのが楽しみです。この値段では大変安いと思います。

This scope catches a lot of flack in the forums and here. Let me demystify some of the bad reviews. 1) Collimation This telescope can be collimated easily by eye, if you want to collimate with a laser, you'll have to remove the corrective lens in the focuser tube. If you love to tinker knock yourself out however, this isn't the most powerful scope you can buy so, eye collimation is more than enough to be happy. 2) The finder scope is unusable While I agree, it's not the best finder scope out there and lining it up with the telescope can take a long time but, it is possible with time and patients. It's also replaceable so if you don't like it, get another one. (note: it is a scope and not a finder, the image is reversed in the finder) 3) I can't see anything out of this thing You need to collimate the scope and line up the finder scope, the instructions are in the manual for eye collimation (tip: back the focuser tube all the way out when you collimate, doing this will let you see both the secondary mirror and the primary, also note, this went through shipping and if it arrived with all the mirrors aligned and ready to go, get a power ball ticket because you'd be the luckiest person on the planet 4) The Barlow is useless Please google and youtube what a barlow is and how to use them, it's not a true lens and once you find out its true purpose, it'll make more sense 5) The 4mm lens is useless See my comment on the barlow, using the barlow with the 4mm will tame things a bit, also, get a lens and filter kit with a 15mm and a 9mm lens. 6) The Telescope doesn't stay put on the tripod. The counterweight on this telescope is not for looks, you need to use it to balance the telescope on the eq mount. when the counter weight is properly balanced, you can put the telescope in any position on the right ascension axis and it'll stay put. The Telescope itself also has to be balanced front to back in the mounting hoops (youtube it, there are a billion tutorials on how to do this.) One last comment on this issue is, do not try to push the telescope into position with the clutches locked, use the controls on the tripod to position the scope, if you need to make big adjustments, loosen the clutches (should be OK because your telescope is balanced) position the scope to the general area of viewing, lock the clutches and use the controls to fine tune. If you push the scope around with the clutches locked you're manhandling the gears that the controls are attached to and you can push them out of whack, don't do this. Here's the deal, this is a marvelous telescope for UNDER 200 American green backs!!! When properly set up, balanced and overall ready to view, it's a great scope and it's a lot of fun. Buying upgrades for the scope will add to your viewing pleasure. Yes you can see our planetary neighbors, the moon looks fantastic, in a dark place, you can see some deeper space stuff. Is this a good scope for beginners? Yes I think it is, backyard astronomy is not a plug and play out of the box and looking at Jupiter kind of deal. A telescope is a pretty sensitive thing that takes a little love. If you're just starting out and collimation, calibration and generic tinkering is not your thing, this may not be your hobby, heck aside from sitting on the couch, I don't know what hobby doesn't require a little hands on setup and tinkering. Finding stuff in the sky is hard, small movements at the scope have a huge impact on where you're looking in the sky, youtube is your friend, so is google.
