Features 6

  • TRIPLE THE POWER OF YOUR TELESCOPE EYEPIECES: This quality X-Cel LX 3x Barlow triples the magnification of any 1.25 astronomical eyepiece. It's perfect for owners of fast, short focal length telescopes.
  • 3-ELEMENT APOCHROMATIC OPTICS: All air-to-glass surfaces are fully multi-coated with anti-reflective coatings. You'll enjoy bright, sharp images with excellent color correction.
  • BRASS COMPRESSION RING: Rather than setscrews, the X-Cel LX 3x Barlow is equipped with a brass compression ring to hold your eyepiece securely in place without the risk of scratching or marring its barrel.
  • ACCEPTS 1.25" FILTERS: The Barlow is threaded to accept standard 1.25" telescope eyepiece filters. Place the filter directly on the Barlow to use it with any eyepiece.

Description

When inserted between the eyepiece and telescope, this premium 3x Barlow lens triples the magnification of all your 1. 25" eyepieces. This is a perfect accessory for owners of short, fast telescopes, and is especially helpful for boosting the magnification during lunar or planetary observations under good seeing conditions. The apochromatic, fully multi- coated optics offer great color correction and contrast. The black anodized housing with orange highlights matches the eyepieces in the Celestron X-Cel LX line. A centralized rubber grip helps to keep your hands securely on the barrel, even when your fingers are cold or you are wearing gloves. A brass compression ring just inside the top of the X-Cel Barlow grabs your eyepiece gently but firmly when you turn the thumbscrew. Once the thumbscrew has been secured in place, the brass ring keeps your eyepiece in the Barlow instead of relying on the tip of the thumbscrew itself, offering a better and protecting the barrel from scratches. The barrel of the Celestron X-Cel LX 3X Barlow is threaded to accept 1. 25" filters, allowing you to change eyepieces without requiring you to remove and re-attach the filter from each eyepiece barrel. Set Contains: 1 x X-Cel LX 3x Barlow Lens 1.25 inches

Zero Loss of Quality for me
Size: 3x - 1.25” – X-Cel LX Barlow Lens Style: X-Cel LX 3x Barlow Lens
Only thing is it’s hard to find objects when you’re super zoomed in - but yeah probably better to get this than an eyepiece that is too powerful for your aperture. Recommend , but take the time to get used to finding objects before showing it off. Fit - Percect. Magnification- Excellent. Brightness - Great. Value - definitely ... show more

Does What It's Designed To Do
Size: 3x - 1.25” – X-Cel LX Barlow Lens Style: X-Cel LX 3x Barlow Lens
A real quality product that works well with my telescope. I'm new to using telescopes so I haven't done enough to make the necessary comparisons but this Barlow Lens appears to do what is was designed to do. I'm still playing with how it connects to the DSLR Camera Adapter and if the image quality is enhanced or limited in any way. I'll provide an update as I get more familiar with the telescope I'm using and the results I'm getting. ... show more

I feel like I was robbed!
Size: 3x - 1.25” – X-Cel LX Barlow Lens Style: X-Cel LX 3x Barlow Lens
Opening) was suprised when I removed it , it was bigger than I imagined. (1st impressions) it appears first impressions was a factor when designing it . Looks good , feels nice . (Utilization) put it in , took a look and was satisfied but just barely. It was humid out so I figured the moist air diminished the quality of what I saw . Well tonight is super clear and went out to look up and thought to compare the stock 3×barlow. When I swapped for the new one I couldnt believe how the new barlow was that much better than the stock barlow. They are both 3×'s and I figured the knew it would look better but it appeared to be 2-3×'s higher magnification and exponentially higher clarity . Im not just satisfied im blown away as well , pisst off is also a good description for the simple fact that the stock barlow is an insult , so celestron if u read this throw that crap away and give a better barlow please ... show more

Performs as expected.
Size: 3x - 1.25” – X-Cel LX Barlow Lens Style: X-Cel LX 3x Barlow Lens
This this is powerful, I really enjoy getting close up views of the moon and planets. The zoom is intense so be sure to if you have a telescope that requires you to move on its own that you position ahead of the earths rotation.

New tricks on an old dog.
I have a 20 year old Celestron 114" Newtonian telescope that was in the attic for a number of years. The really basic eye pieces that it came with back in the day were terrible to start with. I had a ton of fun with them nonetheless. So when the Comet Lovejoy got all the craze, I decided to pull out my old telescope. I cleaned the mirror and looked up. The eye pieces were scratched and utterly useless. So I purchased both the 25mm and the 7mm X-Cel eye pieces and this X-Cel LX 3x barlow Lens. All I can say is holy smokes! It's like a whole new telescope. The clarity and field of view is amazing. The X-Cel LX series of optics is so well worth the price, I really can't say enough of how amazed I was with them. ... show more

Size: 3x - 1.25” – X-Cel LX Barlow Lens Style: X-Cel LX 3x Barlow Lens
This is by far my favorite barlow. I currently have an Orion 2x and a VTE 5x, but this one blows both of them away!!! It's well constructed, heavy, fits really well which reduces the shakiness and the optics are beautiful. I am very happy with this purchase.

Blown away
This is truly a quality piece of equipment. The first time I popped this little guy into my scope and looked at Saturn with something like 260x magnification, I was floored. The image was so crisp and beautiful that it really made me wonder where all the hate for Barlows comes from in the first place. If you are on the fence about getting a Barlow, look no further. For those wondering about the actual size of the piece, it is just about 6 centimeters long NOT COUNTING the end piece that rests inside of your focuser (or other Barlow if you are feeling particularly adventurous). The thicker part of the tube is about 4.5 centimeters in diameter. Despite the bulkier looks, it is actually surprisingly light. Does not come with any sort of case, just the box and the two endcaps. ... show more
