Celestron 21045 PowerSeeker 114EQ Reflectortelescoop - met twee oculairs, Barlow-lens, in hoogte verstelbaar statief en luxe accessoirehouder, Zwart

Vraiment top, les 2 "embout " pour voir a un grossissement different font le job.On voit mieux la lune que sur ma photo prise avec un iphone, je vois rassure, c'est très net!Attention quand même, la lumière de la lune après un bon quart d'heure sans lunette sur le yeux ou filtre fait baisser la vue de l'oeil au niveau de la luminosité, même si j'ai bien tout récupéré.

I have no comparison for this other than the more simplistic Refractor Telescope my father got me as a kid...so now the circle continues, as I got this for my own son. This is the type I always dreamed of getting as a kid, but back then these were in the $500 range and easily too much for my parents growing up. The price point on this for what it offers is awesome, and I selected this after about 6-8 hours of reviewing specs, feedback, and much contemplation. It was this or the 114mm longer tube version, and I opted for this in the end (I figured this had a little more power and it looked more portable than the longer tube of the 114, since we have to go somewhere to view the sky due to the forested yard we have). We have taken it out twice now, & I was NOT disappointed, HOWEVER, a few pointers will definitely help if you're thinking of getting this, to give you the best success chance possible:1) What i read about was VERY true--buy a telecope for the tube itself, NOT the eyepieces it comes with. After MUCH searching I decided upon a zoomable eyepiece to buy along with this: figured this would be a nice way to avoid having to replace eyepieces (it comes with a 20mm and 4mm, and comparing those to this zoomable one is night 7 day difference...the quality and the versatility of the zoomable blows the stock ones out of the water). Its especially nice to start in the 24mm (24x) place, align everything, find your target & focus, then zoom in on it (even with the barlow for additional zooming power), refocus slightly and then enjoy the sight! We successfully located and watched both mars & saturn on our first 2 attempts (using only the free google skymap app for Android to help us locate the planets). What they say about the rings of saturn are so true...you will never forget the first time you see them. It IS a bit small, but you can make them out if everything is in focus and you dont touch the the telescope once everything is in view (until the planet moves out of the field of view, in which case the fine-tune movements of the telescope really shines!). All in all, buy this telescope NOT for the eyepieces, but for the tube itself, which is one of the bets values from everything I have seen. If you pair it with any non-stock eyepiece you will not be disappointed! If you choose not to go with this zoomable one I mention here (that the only additional thing I got for this when I first bought it), even though the price is very reasonable currently @ $51, I'd recommend the 9mm one from Celestron (currently about $20). The stock 20mm eyepiece is "ok" but the stock 4mm I found utterly useless. At least the 9mm aftermarket eyepiece gives you about a 2X zoom vs. the stock 20mm. And then you have to decide if the stock 3X barlow (see next) is worth using at all either.2) BARLOW. Had no idea what this was before I bought this or started researching info about telescopes. Basically its a zooming piece for your normal eyepieces. The stock version that comes with this is "ok" but I dont have anything (yet) to compare it against. Lets just say it "works" to some extent, but all the reviews I read about said this one sucked...to go after an aftermarket 2x or 3x. From all the reviews and research I've gathered, and now using the stock version, I'd say I'd have to agree in all likelihood. Due to this, and since my son seems to have really enjoyed our first 2 outings, I decided to take the next step & get a combo 2x barlow that also serves as a T-adapter to allow for photography! At only $45, that seems like a really good deal, especially since the 3X barlow I found from Celestron was around $80. The 2x combo can be found here: can't say for sure how this will be, but I can tell you it certainly cant be worse than the stock 3x, which seemed very cheaply made (again you buy the telescope for the mirror & tube). Paired with the zoomable aftermarket 8-24mm eyepiece mentioned above and I think itll be a slam dunk. Plus it allows for adapting for use with a digital camera (well possibly non-digital as well, but we have a sony DSLR that should work with the T-adapter for the model we have, which was only about $10...for $55 I get an aftermarket 2x barlow that adapts to allow a DSLR...pretty decent!).3) Other accessories: I have not chosen to get any more than I have listed here, but there was 1 have to mention that I may have to invest in at a later time. One of the concerns about the Newtonian scopes (this is one) was the possibility of having to correct/adjust the mirrors. I chose not to buy the collimator (adjusting tool) out of the box, but was prepared to buy either the cheaper $20 one or possibly the more expensive but from all I can see, more worth it, laser-optics one for about $70. Thankfully it seems my scope did not need it out of the box, but I suspect the lower star reviews that say it didnt work out of the box either had the rare scope that needed it from the get-go, or else the more likely scenario, is that the patience needed to align the finder mini-scope on top of the tube, with the eyepiece view (using the 20mm or in my case, the much better zoomable 8-24x eyepiece, which allows for a much wider field of view than even the 20mm stock) was probably the major factor in most of the low reviews. Having done my research I knew it would require patience when using (see more on that below) and it paid off hugely when you have a 6 yr old and an 8yr old wildly ecstatic with waiting a half-hour to get Saturn's rings into view...see below for details).3) With the accessories out of the way, lets talk about SETUP & USE. First, for setup, I was very meticulous about it and very careful, but from opening the box to final setup & cleanup, I was done in an hour. NO TOOLS were required. Just a touch of patience and carefulness. Seemed very reasonable to me.4) USE: as I mentioned we have taken this out on 2 outings already (have had it less than a week) and both times were widly successful. I have to say that its really useful to have google's free skymap with you when you use this, or even another product I got from Amazon, called Stellarium. Both are good apps and do things a little differently. Together they made finding the planets a breeze and helped us find, focus, and enjoy the views VERY quickly. Both mars & Saturn were easily found using the apps, mars being the easier one to figure out even without the app, due to its orange-tinge color.First, we aligned the mini-scope on top (finder scope) using a distant cell tower as a target (rem the images are UPSIDE DOWN, which when viewing stellar objects is not a big deal). Once we had this aligned (took about 5-10 mins) we located mars, and due to the patience of doing the finder scope, we saw mars in the unzoomed 24x eyepiece ON THE FIRST TRY. So do not skip this step if you can!Now, when we first viewed mars it was a huge fuzzy, hazy blob, with the crosshairs intersected it (in the eyepiece, not the finder scope). I knew we had to focus. So in less than 30 seconds we had it focused and viola! The orange "star" (aka, mars) was seen! The kids were ecstatic! But i told them this was just the beginning :). I zoomed in with the zoomable eyepiece and we could actually make out the slightly crescent shape of mars. But the real goal was saturn's rings! One of the kids had to use the restroom but they said they'd hold it till we saw saturn. I was up against the clock now. but in my 30 mins of use thus far I knew we could do this!In less than 5 minutes later I had saturn in view at low power with rings clearly visible! Kids were in awe (as was i!) and we even tried the 3x barlow (stock). For this, i found that zooming in past about halfway was not very useful. the image was a bit fuzzy. the 3x barlow at 20-24x was good though. I later discovered that this was probably the upper end of the scope's ability to magnify, roughly 250-300X maximum without image distortion/loss. Thus, going back to the barlow section eariler, is why I think a 2X barlow will be great, using the maximum zoom of the eyepiece (8mm).FURTHER THOUGHTS: I hope you have enjoyed my "journey" described here and maybe help someone else decide if this telescope or Astronomy endeavor is worth it and which one to go after. The more expensive motorized ones are probably worth it if you are really into Astronomy, but I could nto afford them (they start around $300 for 114mm scopes, which is pretty reasonable), or the $250+ Dobsonians (non motorized but even more powerful than this one) are a good option too. But i suspect with the low-cost additions I already have ordered noted above, this scope will do just find for now. Plus they have an motorized addition for this thats only around $35, but it does not auto-track. If you align everything properly reviews have said it does help a lot. Thats something else I may invest in down the line. All in all, for under $200 starting, I got this scope & the aftermarket zoomable eyepiece which I almost call a must. For around another $50 you can get an aftermarket barlow that even opens up some astrophotography (but I am sure thats going to take a lot of patience to be successful from what i have read). Good luck and REACH FOR THE STARS! :)

Nice and in good condition received. But i am suggesting that take with motor setWhich 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。
