This is the first reflector telescope ive owned, I read a lot of reviews about how difficult this telescope is to collimate before I bought it and decided I was up for the challenge anyway. It turned out to not be as difficult for me as others suggested it would be. I used both a chesire collimating eye piece and a laser collimator. I was afraid to take the focuser out of the tube and remove the lens to laser collimate it as many people have suggested, so I used the Cheshire collimator first and then used the laser to confirm it was collimated. Next I shined a flashlight through to focuser tube and aimed the telescope directly at the wall to see if the light came out Evenly and it did. The final test was the star test aiming the telescope at a star and two planets (saturn and jupter) and zooming out to show the crosshairs of the main tube lining up with the image perfectly. So all in all, the collimation process for this telescope isn't the monster a lot of people make it out to be in my experience. Due to the primary mirror's shape being spherical rather than curved like true Newtonian reflectors, the trick to collimating this telescope is to have the primary mirror as straight as possible rather than tilt it, then adjust the secondary mirror accordingly to line up with both the focuser tube and the primary mirror. The second thing I want to address is the view which was nice I was able to see the planets saturn and jupiter relatively clearly, but was somewhat obstructed due to the atmospheric distortion between the temperature inside my room and the outside air as its the middle of November and its already quite cold. Something I learned about reflector telescopes is in order to get the best image, the air inside the telescope must match the temperature outside. This telescope is said to max out at 300x magnification, but I was able to push it to 480x magnification using the 3x Barlow lens that comes with the telescope, another 2x barlow lens, and a 12.5mm eye piece before everything became too blurry to see. At that point I could make out a few of Jupiter's colored bands but again the atmospheric distortion hindered the view. The 20mm eyepiece it comes with is ok up to 150x magnification with the 3x Barlow lens but after that the quality drops sharply, so it wouldn't be a bad idea to purchase additional pieces, I haven't really used the 4mm eye piece because the lens is so small it would be a pain to look through so I just stack Barlow lenses with wider eyepieces. Finally the finder scope isn't too bad despite the negative reviews. Mine isn't even perfectly aligned and I had little trouble finding objects in the night sky. Also, this may be a nice "beginner" scope for budding astronomers, but I certainly wouldn't give it to a kid to put together, mainly because of its size and weight. It does take a little tinkering, time, patience, and the right tools to get the most out of it. You'll need a size 2 allen wrench to collimate it. All in all, I'm satisfied for the price I paid for it. I'm glad I ignored all the nay sayers who bash this telescope and its particular design in general. One last thing, be careful with the telescope cap for the main tube, its not as sturdy as it looks and is really the only complaint I have about this product. I've dropped it once or twice and a nice sized crack appeared in it Review: It’s a great scope, but it takes a LOT of practice and getting use to. - I think this telescope is really great for the price. The stand is kind of flimsy, but that is where they went skimpy. I haven't gotten the chance to view anything at night yet. I did set it up the other day and could see individual raindrops hanging on individual pine needles at the end of my driveway (we have a very long driveway). I was super impressed. I do recommend getting the accessory set ($30 on desertcart right now). We are going to order it since the smallest eyepiece that comes with this one is pretty much useless. That is pretty much the deal with any telescope you get though. You'll always have to upgrade eyepieces. Overall, I am very happy with my telescope. Like I said, be prepared to collimate it. Any reflector telescope is required to be collimated though. There are videos on Youtube on how to do it. I haven't attempted it yet but from the tutorials (and using a laser collimation tool) it looks pretty easy if you are handy. I am an engineer so I am really not afraid to work with stuff like this. UPDATE: I have collimated it and used it multiple times now and I am VERY impressed. I will say, the collimating means everything when using it. I recommend collimating at least every month (or after any bump the telescope takes). This will keep your views clear and your time more enjoyable. We also bought the accessory kit like we were planning. I don’t see how you can use this scope without it. We were BLINDED trying to view the moon (quarter moon at the time I believe) and had to go filters that came with the kit. The eyepieces that came with it are higher quality and much clearer than the included eyepieces. I discovered that viewing at night with lights around you ruins the experience. Just having the kitchen light on in the house ruined our views from out in the yard. Make sure it’s as dark as possible. We also learned that your views aren’t anywhere near as good if your eyes aren’t adjusted to the dark. The first time I viewed Orion’s nebula I had just walked outside and viewed it. A few nights later I set up again and waited about 20 minutes outside before viewing and WOW!!!! The difference was incredible. It went from a slightly white cloud to a BEAUTIFUL image with colors and significant detail. We also got to view the andromeda galaxy and that was pretty amazing as well. Tonight’s target is the moon, Orion’s nebula, and the 7 sisters. If you know how to use it, you will enjoy it greatly. I plan on upgrading telescopes eventually because of my experience with this one. These are the items we have bought for or upgraded on the telescope: Binoculars. Got a really good pair at Sams Club. We can see nebulas with them as well. They’re great for finding sky targets. Accessory kit. Get it. Worth every penny. A new finder scope. We got the laser dot one on desertcart for about $20. Totally worth it. The one that came with it is pretty much useless. Sky maps. These help in finding what you want to see. Red flash lights. These are a must have since they will not affect your night vision. I got 6 of them for $9 on desertcart. Some star apps for iPhone. Download Celestrons app. It will help a lot. I also recommend SkyView. Not as good as SkyPortal by Celestron but still good. I also feel like I should mention that the free software package you get for your PC is AWESOME. I really recommend using it. EDIT: I uploaded some pictures I took with my DSLR camera. They are a little blurry because I didn’t have a remote shutter. The camera moved some when I pressed the button. Hoping to snap a shot of Orion soon once I get a remote shutter. ## Features - PERFECT ENTRY-LEVEL TELESCOPE: The Celestron PowerSeeker 127EQ is an easy-to-use and powerful telescope.

I want to be able to see all the planets in our solar system with color, will this do it?** A: I am a novice user who started using this telescope Early Summer 2017. I was able to observe Jupiter and Saturn with some practice and patience. Luckily they were easy to find in the night sky and followed behind the path of the moon. I could make out the colored bands if Jupiter and could see the rings of Saturn with this telescope. It was blurry but still exhilarating!! I can’t wait until next Summer when I can view Mars! **Q: What will i see with this?** A: Great view of the craters on the moon close to the terminator. Jupiter (and possibly the great spot on a very clear night with appropriate filters). Jupiter's moons (point sources) and their movement around Jupiter. Saturn and it's ring(s!). Mars as a red dot. Venus and its crescent. Orion nebula, ring nebula, and a handful of star clusters. Keep in mind that the weather is a determining factor in your observations. Good luck! **Q: I am planning to travel with this. What would be total weight and dimension of this in a packed box along with tripod and all accessories?** A: This is not a scope I would think that would travel well. First off it is a Jones-Bird Reflector design which means it is difficult and somewhat time consuming to collimate. Travel would just complicate that more. The box is fairly large as well - As far as weight 30.9 x 16.9 x 8.5 inches ; 17 pounds assembled - 30 pounds packaged. You would be better off with a small refractor type scope for travel or a small maksutov-cassegrain around 90mm or so. **Q: Is this a good telescope for astrophotography (nebula, star clusters, galaxies?) Can I attach a Canon EOS 60D to this using a T mount?** A: Not with a camera that heavy the mount and counter weight couldn't take the load. To do any good deep sky images you need to put the motor drive on it and its also would handle that heavy of a camera. This telescope can see many deep sky object I have seen M81 (Bode's Galaxy) in Ursa Major. You can put on a Celestron Motor Drive and a Orion 52175 Star Shoot Solar System Color Imaging Camera IV and take great pictures.

I got this one as a Christmas gift. It seemed like a good telescope for basic astronomy, with many nice features. But I was initially quite disappointed by the fact that the images seemed rather blurry. It took me two weeks to correct this problem, to the point where now I am finally starting to like it. 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. I did replace the secondary mirror alignment screws with better stainless steel ones that would not strip, they are metric m4. I then tried to collimate this thing on the North Star (Polaris) and that is, for this one, another pure fantasy. The reason is that Polaris is faint, and every time you move a mirror by a tiny bit (as explained in the Celestron instruction) the star just darts out of view in the eyepiece. More frustration and still no luck in getting this thing in focus. Lastly, I ditched all the Celestron recommendations on day and night collimation (using either the celestron collimation eyepiece or the "ring pattern" for out of focus point sources) and did instead the "EYE-DOCTOR TEST" : I wanted to see how sharp I can get this one, when there is no wind, no shake, no atmospherics, no moving planet, no mist etc. So I placed the telescope at one end of a long corridor in my house, and a nice clean printed envelope with some sharp text on it at the other end. With this method (which I seemingly invented, as it is not described anywhere in the instructions nor on the Celestron site) I was finally able to adjust (by very small increments) the three screws on the secondary mirror till I FINALLY got a nice sharp picture of the writing on the letter. Note that this last procedure did NOT require the collimating eyepiece! Just the regular 4mm eyepiece that comes with the telescope. Success! As a by product, I found that in fact in the end all three eyepieces work rather well, down to the 4mm which is a bit faint, the 20mm with the 3X Barlow is better. Now I can finally see the main two stripes on Jupiter and the Orion Nebula with some clarity. In conclusion: Plusses : Potentially sharp optics and large aperture. Reasonable price. Sturdy mounts. Useful eyepieces. Cons: Imo optics needs to be carefully aligned by the method described here. Mine was definitely NOT aligned and, initially, as a result disappointingly blurry. EDIT: After a few more weeks of use (February 2014), I spent some time using the Celestron collimation 1.25" eyepiece ($28 here on Amazon). My conclusion is that it is a very useful, if not essential, tool for this telescope. To avoid any further issues due to my previous messing around, I first screwed in the secondary mirror (by loosening up the three alignment screws, and pulling in the secondary mirror all the way in until it barely touches the mount), and later pulled out the primary mirror as well(by pulling out all six screws until the whole unit comes out, then reinserting the mirror after making sure the secondary was pointing the right way, straight to the back). Then, using the Celestron collimation eyepiece with its crosshair, I carefully adjusted the secondary and primary orientations (three screws for each mirror) until all the crosshairs overlapped perfectly. In other words, the crosshair in the eyepiece has to overlap perfectly with its reflection through mirrors 1 and 2, and back to the eyepiece. This takes time and patience. After having done that, the image quality seems pretty good and rather sharp. I went down to about 8mm, I don't recommend getting lower than that. The best setup for this one is the 20mm eyepiece, either by itself or with the included 3x Barlow (which then gives 20/3 = ca. 7mm). I also got some Ploessel eyepieces, but they will do you no good if the mirrors aren't aligned first. PPS. I found (April 2014) that the best way to collimate this (Bird-Jones or catadioptric design)telescope and get nice sharp images is to remove the focusing lens at the bottom of the focusing tube (takes 10 mins), align the secondary and primary mirrors with an inexpensive LASER collimator (mine is an LK1 $30 from seben dot com, takes another 10 mins to do this part), put the corrector lens back in and reinsert the focusing tube (don't touch the lens with your hands, takes around 5 mins). With this method the results are guaranteed to be reproducible and consistent. The images are then consistently sharp. PPPS. The other day (June 2014)I talked at length to a very nice and helpful person at Celestron technical support (Will?). He suggested to check the following thing. The secondary (smaller, flat) mirror is oval-shape and mounted right under the focusing tube, held in place by three (outside)-plus-one (center) screws. Now put a focusing cap (just an eyepiece cap with a small 1mm hole in the center) at the (top) end of the focusing tube. Then make absolutely sure (after you take again very carefully the correcting lens out of the focusing tube) that the inside of the focusing tube and the secondary mirror, as viewed through the focuser, are perfectly concentric when you view them through the hole in the cap. That is, the secondary mirror has to be perfectly centered when viewed from the top of the focusing tube. Note that the secondary mirror is oval shaped, but will look like a perfect disc when tilted at about 45 degrees. On mine this required several turns on the (secondary) center screw. After this is done, make also sure that the tilt on the secondary mirror is such that you can see the center of the primary mirror (on mine I put a black pen mark at the dead center). Now re-align the secondary and primary mirrors with a laser (in my case), with the cap with a hole, or a cheshire eyepiece. Then put back the correcting lens in the focuser, and you are done. The end result is that on mine it improved the sharpness a bit (I did the eyedoctor test again). I was also able to see more detail on Saturn with a standard 9mm eyepiece, will try taking a few pictures soon. PPPPS: This telescope really shines (due to the light gathering abilities of it's fairly large mirror) when you want to look at fainter objects. Recently we had good viewing conditions and I had a chance to look the the Great Cluster in Hercules (M13), the Lagoon Nebula (M8), the Omega Nebula (M17), and two more star clusters in the same general region (M4 and M62). I took some fairly nice pictures of these objects with a Sony HX200 camera (30x zoom) mounted piggyback on the telescope, using the Celestron motor drive for the 127EQ and long 30sec exposures at 800ISO. See the pictures I posted on the right. I was surprised how well the telecope mount, equipped with the Celestron $30 clockdrive, works when taking long exposures. PPPPPS: It's October, seven months after I did the laser collimation, and everything is still fine and exactly the same. That tells me that the collimation on this one only needs to be done once, maybe if it gets out of whack during shipping. After that there's no need - unless you bump it or drop it badly. At least that's my experience. PPPPPPS: It is end of February 2015 now, and I had some very good views of the great Nebula in Orion M42. The scope is still perfectly collimated since almost a year ago, last time I did the collimation with a laser. Again, the message here is that if you spend the time to collimate it properly and don't bump it after that, it will stay sharp almost forever ... Btw I love the $32 celestron R/A single axis motor drive on these telescope, and in my opinion it is a very worthwhile investment. Objects stay in view for almost an hour w/o adjustments. ## Frequently Bought Together - Celestron 21049 PowerSeeker 127EQ Reflector Telescope, Black - Celestron – Smartphone Photography Adapter for Telescope – Digiscoping Smartphone Adapter – Capture Photos and Video Through Your Telescope or Spotting Scope Eyepiece - Celestron 94119-A 1.25 inch Moon Filter - Suitable for Lunar Observation, Extra Bright Planets or Terrestrial Viewing Over Sand or Snow, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/1144597-celestron-powerseeker-127eq-reflector-telescope-for-home-astronomy](https://www.desertcart.gr/products/1144597-celestron-powerseeker-127eq-reflector-telescope-for-home-astronomy) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-26*
