## Overview

The Celestron 93436 2 Inch Luminous 2.5X Barlow Lens is a premium telescope accessory that multiplies eyepiece magnification by 2.5x. Featuring fully multi-coated 4-element apochromatic optics, it delivers sharp, high-contrast images free from color distortion. Its hard-anodized aluminum barrel is threaded for 2" filters and includes a brass compression ring for secure eyepiece attachment. Compatible with both 2" and 1.25" eyepieces via the included adapter, it offers versatile use backed by a 2-year US warranty and dedicated support from a trusted brand since 1960.

## Description

The Celestron 2" Luminos Barlow Lens increases the magnification of your 2" and 1.25" eyepieces by 2.5x. The premium 4-element apochromatic optics are fully multi-coated for optimum light transmission and yield high contrast, true color images. The beautiful hard-anodized aluminum housing matches the eyepieces in the Celestron Luminos 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 Luminos 2.5x Barlow grabs your 2" eyepieces gently but firmly when you turn the oversized 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 grip and protecting the barrel from scratches. A matching 2" to 1.25" adapter is included so that you can increase the magnification of all of your eyepieces, both 1.25" and 2", in this versatile Barlow lens. The insert barrel of the Celestron Luminos 2.5x Barlow is threaded to accept 2" filters. This is a nice feature, because you can change eyepieces without removing and reattaching the filter each time.

Review: Absolutely outstanding workmanship, especially for the price! - An important rule to remember: When it comes to adding anything to your optical path in astronomy, don't shop "on the cheap". You will be sorely disappointed with the results. If you can afford a Televue, do it. If not, the Celestron Luminos is the best bang you can get for your buck. 4 elements. This thing is not only gorgeous for visual observation, but it's outstanding for astrophotography. Strongly recommended.
Review: Great purchase - Solid, not too heavy. And could get focus on a nextstar slt 130 with astro camera without issue. Have to be careful though, looking at Jupiter with this and an eyepeice was quite bright, needed to use a filter. However I so suffer from light sensitivity, so probably not an issue for others

## Questions & Answers

**Q: Does this barlow come with dust caps?**
A: Yes, the Luminos 2-inch 2.5x Barlow Lens comes with dust caps and a vinyl drawstring pouch for storage. Sincerely, Garrett at Celestron

**Q: Will this work celestron 6e ? what adapters do i need if any? thank you**
A: It's a 2 inch diameter barlow. If your current setup can handle a 2 inch eyepiece, there is no issue. Not familiar with your 6e. I'm not an experienced astronomer but I think a 2 inch barlow is probably overkill for a 6 inch mirror assuming it can accept the piece.

**Q: I bought this barlow for use with a 12inch Meade. Well constructed lens, but can't get the image in focus, even with an extender. Recommendations?**
A: I had to use 3” extra to focus it in my RC 8”.
Can you try it even farther? Even just holding the eyepiece/camera farther by hand can give you an idea.

**Q: I have a starsense 102az. i do not have a 2” diagonal. can i use this in between the objective and the 1.25” diagonal that comes with the telescope?**
A: No, you're going to have to buy a 2 inch diagonal to use this eyepiece.
