1.25-inch 5X Barlow Lens & Moon Filter Kit-for Telescope Eyepieces

A Must-Have Accessory for Any Stargazer – Elevates Your Telescope Experience!I recently purchased the Starboosa 1.25-Inch 5X Barlow Lens & Moon Filter Kit for Telescope Eyepieces, and I can confidently say it’s one of the best additions I’ve made to my astronomy setup! As an avid stargazer, I’m always on the lookout for accessories that can enhance my viewing experience without breaking the bank, and this kit absolutely delivers on both quality and value.First Impressions and Build QualityRight out of the box, I was impressed with the sturdy construction of both the 5X Barlow lens and the moon filter. The Barlow lens feels solid in hand, with a sleek black finish and clear labeling that reads "5X Barlow Lens – Fully Multi-Coated." The moon filter also has a premium feel, with a threaded design that makes it easy to attach. Both pieces are made to fit standard 1.25-inch telescope eyepieces, which is perfect for my setup (I use a Celestron telescope, for reference). The packaging was secure, and everything arrived in pristine condition, which is always a plus when ordering delicate optical equipment.Performance – Barlow LensThe 5X Barlow lens is the star of this kit (pun intended)! For those unfamiliar, a Barlow lens increases the magnification of your eyepiece by the stated factor—in this case, 5X. I paired this with my 10mm eyepiece, which normally gives me a decent view, and the Barlow transformed it into the equivalent of a 2mm eyepiece, providing incredible magnification. I was able to get jaw-dropping views of Jupiter’s cloud bands and even spotted some of its moons with stunning clarity. The fully multi-coated optics really shine here, as I noticed minimal light loss and no noticeable chromatic aberration, which can sometimes be an issue with lower-quality Barlows. The image remained sharp and bright, even at higher magnifications, which is a testament to the quality of the lens.One thing to note: because this is a 5X Barlow, it does significantly increase magnification, so you’ll need a steady mount and good seeing conditions to get the most out of it. On nights with a bit of atmospheric turbulence, I found it better to switch to a lower-power eyepiece, but that’s more about my telescope’s limitations than the Barlow itself.Performance – Moon FilterThe moon filter included in this kit is a game-changer for lunar observation. Without a filter, the moon can be overwhelmingly bright, especially during a full moon, which washes out details like craters and maria. This filter screws easily onto the bottom of my eyepiece, and the difference was immediate. It reduces glare and enhances contrast, allowing me to see fine details on the lunar surface that I’d never noticed before. I spent an entire evening exploring the Sea of Tranquility and the craters along the terminator line, and the experience was nothing short of magical. The filter has a neutral density, which means it doesn’t tint the moon in an unnatural way—just pure, crisp, detailed views.Ease of UseAttaching both the Barlow lens and moon filter to my telescope was a breeze. The Barlow lens slides into the telescope’s focuser (or diagonal, depending on your setup), and then you insert your eyepiece into the Barlow. The moon filter screws onto the threaded end of your eyepiece before you insert it into the focuser or Barlow. It took me less than a minute to set up, and everything fit snugly with no wobbling or misalignment. The 1.25-inch size is standard for most beginner and intermediate telescopes, so compatibility shouldn’t be an issue for most users.Value for MoneyThis kit is an absolute steal for the price. You’re essentially getting two high-quality accessories—a 5X Barlow lens and a moon filter—for the cost of what some brands charge for just one of these items. The fact that it’s an Amazon’s Choice product and has over 100 purchases in the past month speaks to its popularity, and I can see why. It’s a fantastic option for beginners looking to expand their telescope’s capabilities or for seasoned astronomers who want a reliable, budget-friendly addition to their collection.Final ThoughtsThe Starboosa 1.25-Inch 5X Barlow Lens & Moon Filter Kit has truly elevated my stargazing experience. Whether I’m zooming in on distant planets with the Barlow or marveling at the moon’s intricate details with the filter, this kit has made every night under the stars more enjoyable. The build quality, optical performance, and ease of use are all top-notch, and I can’t recommend it enough to anyone looking to get more out of their telescope. If you’re on the fence, don’t hesitate—this kit is worth every penny and then some. I’m already looking forward to my next clear night to explore more of the cosmos with this fantastic accessory!

I bought this lens to go along with my 16 year old son’s telescope, and he was really happy with it. He still uses all of his lenses with his telescope to learn about and view the planets, stars, eclipses, etc. Finally he has found an interest to keep him busy other than Roblox!

Haven't used it yet, but it seems well enough made. It's not one of those silly plastic ones. My biggest complaint is that it is labeled 5x Barlow lens. I almost freaked out when I saw that, as I ordered the 2x selection, considering I already have a 5x and learned the hard way that a 5x is too powerful for my telescope. (I openly admit I am a total noob at this, but I do love astronomy regardless)It wasn't until I revisited the product page here on Amazon, and saw in the description it says that despite being labeled 5x, it's actually a 2x Barlow lens. With that, I calmed down a little. I can handle that. Figuring out a way to relabel it should not be hard at all. Anyway, that little labeling snafu lost this product one star in the review. I will follow up on this review after use.

Does exactly what it says, just doesn't benefit my particular scope much (8" dob). Not much different than my 2x, so I'm probably exceeding meaningful magnification.

Does its job I guess. Value for the money. Moon filter is pointless though ..

Just what I needed
