Bought for my partner for our anniversary, he's gotten a lot of use out of them and has had no issues

Estuve mirando durante tiempo un producto similar y este maletín es super completo, con filtros de colores y augmentos; no incluye filtro para el Sol, pero igualmente es buenísimo. Buen material, bien protegido

The quality and variety of the optics in this kit are great. They're not top of the line (that's the X-Cel line), but for an amateur looking to have fun with his telescope and also be conscientious of his budget, the price is unbeatable. The pieces I use the most are the moon filter, the 32mm, the 17mm, and the 6mm. Just these pieces alone cost more than the kit, and you have all the other items to play with, plus the case which is actually pretty nice and customizable (I cut extra holes in it to fit my erect image lens and a few other optics I had). The barlow is ok, nothing to write home about. Definitely recommend it if you don't already have the pieces I mentioned.

This is an amazing price for this many eyepieces and filters. These are high quality Plossl (4 elements) eyepieces. The selection of filters is about all you will ever need. I haven't used my telescope for a while and managed to lose the eyepieces so I bought this set. These are better quality eyepieces than I originally had so it was fortuitous.Plossl eyepieces sell for around $40.00 each, and the Barlow costs about the same, so 5 eyepieces and a Barlow bought individually would cost about $240.00. Filter prices range all over the place depending on quality. The cheapest I found was a set of six filters from Orion for $120.00. Don't forget to add in the padded case for about $50.00 to arrive at $410.00. While this set offers great savings, the advertised claim that the value is over $700.00 is greatly exaggerated. However, a $280.00 saving is still a great deal.For the novice. magnification is calculated by dividing the focal length of the Mirror (reflector) or Primary lens (refractor) by the focal length of the eyepiece. For example, my telescope has a focal length of 1,000 mm (1 inch = 25.4 mm), so the 32 mm eyepiece gives me 1,000/32 = 31x. Perfect for looking at nebulae like those found in Orion. At the other extreme, the 6 mm lens gives 167x, and the Barlow doubles that to 334, good for studying Mars (If the planetwide dust storm ever settles).I recommend buying these other items to enhance your experience.1) I use a medium sized refractor for most of my observations so a diagonal prism for ease of viewing is almost essential. Reflectors don't really need diagonals because of the position of the eyepiece. The one I bought is "Meade Instruments #918A 1.25-Inch Diagonal Prism." for $29.99. Here is the link: https://amazon.com/gp/product/B0006NAS8K/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=12) A light pollution filter if you live in an area with a lot of street lights. there are some very expensive ones, but, I bought the "Gosky 1.25 Inch Light Pollution Filter for Telescope" for $19.99. Here is the link: https://amazon.com/gp/product/B01LGZNMGG/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=13) Optional, 4mm eyepiece for higher magnification. Most complete sets of eyepieces have the 4 mm eyepiece, so I was surprised it was not in this set. No matter, it is still a fantastic set. I bought the "Celestron Omni Series 1-1/4 4MM Eyepiece" for $23.00. Here is the link: https://amazon.com/gp/product/B00008Y0S5/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1The case has a couple of slots cut out in the foam liner for the addition of extra pieces. Using the cutouts you can store the extra filter, eyepiece, and diagonal in the case. I removed the foam from the filter area to store the extra filter and as luck would have it, it was the perfect length to use as a spacer between the diagonal and the extra eyepiece (eyepiece hasn't arrived yet). You can always cut the foam that you remove from the large cutout area, it was just nice to have the perfect fit. As you can see from the photo (Amazon rotated it 90 degrees) it all fits nicely.This is the perfect set for casual astronomy buffs who don't want to mortgage their houses to buy astronomy equipment. Since it's Celestron, you can count on it being good quality.

Cet achat a été effectué en complément indispensable au télescope Celestron NexStar 4 SE.Je n'ai rencontré aucun soucis de compatibilité.Tout s'emboite parfaitement.Les filtre et les différents objectifs sont tous très bien protégé dans leur plastique puis dans la mousse prédécoupée à leur forme qui tapisse la mallette.Cet ensemble me convient tout à fait, le rapport qualité prix a été imbattable pour moi.Je recommande vivement

I've been eyeing this kit ever since I bought my first telescope just over a year and a half ago (Celestron PowerSeeker 114EQ). I got that one used from the warehouse, it came in almost new condition (in fact, I would not have known the difference if I didn't make the purchase).The same is true here, all original packaging, however it was missing the keys, which I did not plan on using anyways, and it was also missing the filter guide (which is a non issue, really. This is why Google exists).The eyepieces themselves are very nice, metal barrels that are a very tight fit in my scope. I mention this because the two beginner EPs that came with the 114EQ are loose fitting and plastic.The glass is very clear, only viewed a church steeple a mile away (it was cloudy last night when I received them, will update once I view the sky with these). Image was very clear across all sizes. The barrels are threaded for filters, which screw in very nicely. Again, will update this section later.UPDATE: Was able to do some observing with these: the clarity is astounding compared to my beginners. I was able to distinctly see the individual stars in the Orion Nebula, specifically the four star group in the middle of it. Before, I could only just make our that I was seeing M42.A huge plus: the EPs are set to (almost) the same focus, so you don't have to refocus much when switching lenses, unlike the beginner EPs.Other thoughts: The case has enough space to hold my laser collimator, my other two EPs and barlow, as well as my mini screwdriver that I use for collimation.tl;dr: HUGE value, great quality, highly recommended to build your EP collection. I cannot be pleased enough with this acquisition!!!

I picked up this set of eyepieces and filters after first getting the Celestron Powerseeker Accessory kit with the 15mm and 9mm Kellner eyepieces to go with my Celestron Powerseeker 80EQ (refractor) and Powerseeker 127EQ (reflector) telescopes in order to gain a feel for how the different sizes of eyepieces worked before taking a big plunge and getting a larger set like this one with more options and advantages with the Plossl type of eyepieces. I did my homework before buying and calculated out the maximum magnifications that both telescopes could support in terms of stand-alone eyepieces or in combination with the included 2x Barlow and all of the set's eyepieces were within the limits of the 80EQ refractor as standalone but beyond the 13mm couldn't be used with the 2x Barlow (the 127EQ reflector could use up to the 8mm + 2x Barlow) and still focus sharply, so bear that in mind when considering this set relative to your own telescope's capability/limitations.Since I have astigmatism and prefer to keep my glasses on when doing observations whenever possible, the biggest advantages of this set have come from using the 32mm, 17mm, and 13mm Plossl eyepieces alone or in combination with the 2x Barlow to get the clearest and most comfortable views. These have proven to be superior to the Kellners I picked up originally and are now my go-to choice for observations. The 32mm is particularly useful for star-hopping and locating what I'm looking for before getting a closer look with either the Barlow or one of the smaller eyepieces and then stacking the Barlow to get even closer views. The multi-coated lenses deliver outstanding clarity for both planetary and stellar observations and I'm very pleased with them as a result. I've combined these with a star diagonal in the refractor and have been successful in observing several Messier objects as well as some splitting out various double and triple stars at high power magnification along with the usual nice views of the Moon, Jupiter's cloud bands and moons, crescent views of Venus, etc. The smaller 8mm and 6mm eyepieces have proven less useful due mostly to eye relief issues and magnification limits but are still good eyepieces to round out the set and provide some options for those who don't have to contend with eyeglass interference like I do. I've used a clock motor drive with them effectively to keep items of interest within the field of view at higher magnifications and allow my eye to 'roam' around freely and see more as a result.The filters that the set includes are a nice value-add, but the best of the lot has proven to be the Neutral Density (ND) Moon filter. It provides sharper views and greater detail than the 'green' Moon filter that comes in the Powerseeker Accessory kit in my opinion and is a marked improvement for sure as it keeps the moon's natural color without adding the green tinge while still reducing the brightness to bearable levels even when beyond Half Moon stage. I've played around with the various planetary filters mostly while viewing Jupiter and didn't really see a huge added improvement with the various filters but they are there as an added bonus. The real value of the set is definitely in the eyepieces and the multi-coated 2x Barlow.The case is also very handy, just the right size, lightweight but durable due to the aluminum construction. The foam inside is typical egg crate type cushioning foam. I've modified the foam inside slightly to accommodate all of my eyepieces (including the Kellners from the earlier set) and my night-vision red LED flashlight so everything all fits in one box.All in all, I'm very pleased with the set and the expanded capability it provides for the price. It's given me a very solid foundation to work from should I decide to go all-out in the future and buy specialized eye-pieces to further compliment this broad range of options I now have with this set in the collection.

Just got it...Happy with the package from courier. Product looks good. I don't see any deficiency in quality..well made.Atmosphere is cloudy...so waiting to use the lens.
