I bought this for my Meade DS 2000 series telescope. (it's a 4.5 in reflector with a 1000 mm focal length). I used it to look at Saturn tonight and I was able to visibly see the rings of Saturn. To clarify for everyone, many people have been saying the included 6 mm is too powerful, this is not true. The 6 mm by itself worked fine and I was able to get it in focus. I wasn't able to get it in focus with the Barlow attached, it was just too hard to focus. The Barlow is great and worked with some other Meade lenses I had as well. Great experience thus far. I have no issues with any part of this product. The whole set has worked out great and I am very satisfied with the optics, clarity, and the quality of the build. It's a great set and by far a much cheaper alternative to buying just a Barlow or buying one of the 150 dollar sets. You will always get higher quality when you spend more money and buy each eyepiece separately but as far as bang for your buck it doesn't get much better than this. I would recommend this to anyone with a reflector telescope.

I purchased this for the Celestron Powerseeker 80EQ and it has made a wonderful addition to my scope. All three eyepieces are made with good to great quality. The red and blue filters are medium quality, although the moon filter is plastic it does it's job well. My favorite eyepiece is the 15mm and with the blue filter attached i can see the cloud bands of jupiter as well as the big red storm. The 6mm is made better as it is a standard plossl and it is capable of showing planets and brighter galaxies (Andromeda, M81) very well. Also the 2x barlow is great because is contains the threads that can be used for attaching a dslr camera. For you to do this you will need the correct t-ring for your camera. If you only have a standard digital camera you can find the Celestron or Orion universal camera adaptor here on Amazon. I have seen more detail in the moon with my scope and these eyepieces than i could ever draw in my life. If your about to buy a telescope and are looking for more power and better veiws than this is the kit for you. Although i would not use the 6mm eyepiece with any scope under 60mm; due to light loss from to much power. With the celestron powerseeker 80eq the power of these eyepieces are as follows 15mm-60x, 6mm-150x. You can then double the magnification of both eyepieces with the included 2x barlow. Also the barlow can be used with any other eyepieces you may have that are 1.25". To see how much power these eyepieces will give you for your current telescope or one different than mine you use this formula, focal length divided by the size of the eyepiece. Example, my scope has a focal length of 900 so i take 900 and divide it by 15. If i had to do it over i would still purchase this product. I would recomened this for anyone over the age of 8 for a great way of upgrading your telescope.

The lenses feel high quality, have given me excellent, clear views of the stars and planets. The case they come in is incredibly poor quality plastic, hasn't latched back since I opened it the first time, but the padding inside the case is enough to protect the lenses. I have a large carrying case to put my scope and all my equipment in and the case fits in the pocket keeping it closed, otherwise it would fall open.

Well worth the money, I only wish I have bought them sooner, the moon filter is a definite plus and the extra magnification makes you feel like you are on the moon. I can't wait to have the chance to view the other planets.

I am a 34 year old beginner in astronomy and just bought my first telescope 6 months ago. I got a celestron astromaster 114 (Newtonian 4.5") but up until now I was limited to the 10mm eyepiece and the 20mm erect image eyepiece that come with it. I wanted to get a few more eyepieces and some planetary filters without spending much, so I decided to get this kit. So far I have used my scope around 20 times since I bought it... so, I don't have much experience in the field, but here are my comments:

Ok! so, the optical quality of the eyepieces... I know these are from the economic line but they are still very good, I specially liked the 15mm one and I use it a lot to observe the moon and the stars. The 6mm is also good but the images do get a bit blurry at least on my scope. Even so, I use it to observe details on the surface of the moon and Jupiter when I want to increase the magnification power.

I tested the x2 barlow lens with all the eyepieces I have and it works fine, although the image quality is not as good as with a single eyepiece (i.e. it's better to use a 10mm eyepiece than a 20mm plus x2 barlow). However, I really like using it with the 20mm erect image eyepiece that came with my scope (for terrestrial observation).

The blue filter is great!, I tested it observing Jupiter and it reduces the glare significantly making the planet's bands easier to observe. You will see the planet a bit blueish, of course... While observing Jupiter, I like swapping between the 6mm eyepiece with the blue filter attached and the 10mm eyepiece with no filter.

The red filter didn't work so well with Jupiter (all I could see was a uniform-red disc), I read somewhere that it is more used to observe Mars but haven't had the chance to test it yet. The moon filter is made of plastic (the others are made of aluminum) and it works ok removing the glare during the brightest phases, although the image becomes a bit greenish. If you like to observe the moon you will probably want to get a better filter for it (I got this one... http://www.amazon.com/gp/product/B0069VY9CO/ref=cm_cr_ryp_prd_ttl_sol_0). All filters can be screwed to the bottom of the eyepiece nice and smoothly.

Overall I'm very happy with this kit, I really recommend it if you are a beginner in astronomy because you can learn a lot using it without spending much, later you'll find out what works best for you and then you can put a little more money into it... Until then, you can get a lot more from your telescope with this kit. if you do the math, you're paying around $7 USD for each accessory, so the cost-benefit ratio is really good.
