THE SKY'S THE LIMIT WITH TELE VUE!

The planets and heavenly bodies never looked so great until I used a Tele Vue Barlow lens with my 9mm Nagler. I was able to see Jupiter & Saturn very clearly at 450X with my Meade 8" SCT. It makes a real difference when you use quality lenses! I strongly recommend that you switch to the Tele Vue Barlow lens, since it will make a world of a difference when you want to see crisp and detailed features on planets, nebulas and other magnificent objects in space.

Amazing!

I have Celestron 5SE and planets in my photos just seemed blurred and tiny. I read that this TeleVue barlow is amazing for planet photography so I decided to try it out. Well, simply put, it’s amazing! Planets in my photos are much sharper, bigger, and colorful. In addition, just using this barlow with eyepieces makes a big difference. Get it, you won’t regret it!

Quality Barlow from Tele Vue

This is a well made Barlow that provides great views with additional eyepieces. It feels very heavy and consists of nice materials. Compared to other Barlow's I've gotten as part of a package this is a far superior product. 1.25" filters easily screw into the Barlow as well. Very sturdy, all around great product. You get what you pay for with Tele Vue.

Great Upgrade to your Eyepiece Collection

I was very active in amateur astronomy in the 80/90/00. Aperture fever took me from an 8” Meade to a Celestron 11”. Never had a desire to own a Barlow. This TeleVue 2X has changed my mind. Works great with my far more portable 5”Celestron NexStar that better fits my advancing age! Another excellent product by TeleVue. Never buy any other brand!!

TeleVue Quality

The Tele Vue 2X Barlow is far superior to the Barlow that came with my scope. For some time I have suspected that my disappointment when using a Barlow was because the Barlow I was using was of poor quality. The Tele Vue has renewed my faith in Barlows. Also, this Barlow comes apart so that I can just use the half that contains the optics. Helpful for astrophotography. The Tele Vue Powermates are even nicer, but kinda spendy.

Made a difference

I purchased the Tele Vue Barlow to replace the 2x Celestron Barlow that came with my telescope 8"sct. Using a 9mm Orion Expanse eyepiece I noticed a definite difference in contrast when viewing Mars and Jupiter May 2014.

OK for this price

I use it on Orion 8" It's OK for 15mm and up With 6mm it's unusable, with 10mm not so clear.

Worth every penny

It is like the Barlow wasn't there. The image is just twice as big -- clear and sharp. If you haven't tried a televue eyepiece, you should know they are addictive.

Experience the exceptional performance of the Tele Vue 2" 2x Big Barlow Lens, a high-quality optical accessory designed to enhance your stargazing experience. This versatile lens is ideal for Newtonian scope owners, offering a 2x magnification that amplifies power and improves eyepiece sharpness.

The Big Barlow Lens is parfocal with both 2" and 1-1/2" eyepieces, ensuring a seamless transition between different eyepieces. It features a 1-1/4" eyepiece adapter and threads for 48mm filters, providing flexibility and adaptability for various viewing scenarios.

Designed with the user in mind, this lens includes a captive lock screw and full multi-coatings, ensuring durability and longevity. The Tele Vue Barlow line was crafted to complement the high performance of our eyepieces, using only two elements of high-index glass to reduce all aberrations to well below the airy disc in an f/4 system.

This lens is a testament to Tele Vue's commitment to quality, using multi-coated high index glasses for optimum aberration correction and exceptional contrast with virtually no light loss. The result is an aberration-free performance, even when tested with f/4 scopes.

The Tele Vue 2" 2x Big Barlow Lens also features brass clamp rings for secure, non-marring holding of eyepieces and accessories. However, please note that the Big Barlow is not recommended for use with 2" diagonals due to its length, which may prevent it from being parfocal.

In conclusion, the Tele Vue 2" 2x Big Barlow Lens is a reliable, efficient, and high-quality optical accessory that enhances your telescope's performance, providing a superior viewing experience.
