It worked out-of-the-box with my 12" dob and resolved my inward focus issue completely. I was able to capture stunning frames of Jupiter and Saturn right from my light-polluted backyard with minimal setup and NO TRACKING. Just what I needed! :) Review: Nice workmanship, but 1.25” interior lens, not 2” - Themis Barlow eyepiece is very nicely constructed. However, the interior lens diameter is 1.25”, not 2”, which obviously lets-in less light through the lens. Decent value for the money, but not very practical for good nighttime viewing in low light conditions. ## Features - Precision 2.5x Magnification Boost: This 2.5x deluxe barlow lens delivers authentic 2.5x magnification without compromising edge-to-edge sharpness; perfect for capturing planet or lunar rille details at extended focal lengths - Professional-Grade Multi-Coating System: Feature fully multi-coated apochromatic lens system with 4 elements design; effectively minimize chromatic aberration and ensure clear and sharp imaging performance; perfect for high-contrast planetary observation - Engineered with Mutiple-Layer Material: Constructed from anodized aluminum provide using cycle and lightweight portability; Integrated with premium optical glass significantly enhance chromatic aberration correction and deliver exceptionally better image - Double Adapter System: Functions as 2 inch to 1.25 inch adapter enable compatibility with 1.25" & 2" eyepiece as well as other telescope accessory of same diameter; equipped with precision CNC-machined brass compression ring and dual knurled thumbscrews - 2 Inch Bottom-Mounted Design: This 2 inch telescope barlow lens includes 2" tube diatemer that connect to 2" telescope focusers or other 2" telescope accessories and M48x0.75 female thread to connect to 2" telescope filter with M48x0.75 male thread ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0140UAG7M | | Additional Features | 2.5x Magnification, Equipped with 1.25 Inch & 2 Inch Eyepiece Connecting Ends, Equipped with Filter Thread | | Best Sellers Rank | #22 in Telescope Barlow Lenses | | Brand | Astromania | | Built-In Media | 1 x 2.5x Barlow Lens, 2 x Dust Covers | | Coating | Fully Multi-Coated | | Compatible Devices | 1.25 Inch Eyepiece, 2 Inch Eyepiece, Telescopes with 1.25-inch Focuser | | Customer Reviews | 3.6 out of 5 stars 27 Reviews | | Exit Pupil Diameter | 20.4 millimeters | | Eye Piece Lens Description | Barlow | | Field Of View | 2.45 degrees | | Finderscope | Reflex | | Focal Length Description | 20 inches | | Focus Type | Manual Focus | | Item Weight | 5.6 ounces | | Manufacturer | Astromania | | Manufacturer Part Number | SKU_AM_BL2X4 | | Model Name | Astromania Upgraded 2.5X 2 inch Barlow Lens | | Model Number | SKU_AM_BL2X4 | | Mount | Fixed Mount | | Objective Lens Diameter | 25 | | Power Source | Manual Operation | | Telescope Mount Description | Fixed Mount | | Unit Count | 1 Count | | Zoom Ratio | 2.5:1 | ## Images ![Astromania Barlow Lens 2", 2.5X Barlow Lens for 1.25/2" Telescope Eyepiece - Image 1](https://m.media-amazon.com/images/I/7175mwLp5lL.jpg) ![Astromania Barlow Lens 2", 2.5X Barlow Lens for 1.25/2" Telescope Eyepiece - Image 2](https://m.media-amazon.com/images/I/713paofAiRL.jpg) ![Astromania Barlow Lens 2", 2.5X Barlow Lens for 1.25/2" Telescope Eyepiece - Image 3](https://m.media-amazon.com/images/I/71vEA+PXRyL.jpg) ![Astromania Barlow Lens 2", 2.5X Barlow Lens for 1.25/2" Telescope Eyepiece - Image 4](https://m.media-amazon.com/images/I/71zQfNgPZzL.jpg) ![Astromania Barlow Lens 2", 2.5X Barlow Lens for 1.25/2" Telescope Eyepiece - Image 5](https://m.media-amazon.com/images/I/717sEYGgUIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Barlow *by P***K on July 10, 2020* What a great barlow, perfect for prime focus astrophotography. It worked out-of-the-box with my 12" dob and resolved my inward focus issue completely. I was able to capture stunning frames of Jupiter and Saturn right from my light-polluted backyard with minimal setup and NO TRACKING. Just what I needed! :) ### ⭐⭐⭐ Nice workmanship, but 1.25” interior lens, not 2” *by R***H on July 15, 2020* Themis Barlow eyepiece is very nicely constructed. However, the interior lens diameter is 1.25”, not 2”, which obviously lets-in less light through the lens. Decent value for the money, but not very practical for good nighttime viewing in low light conditions. ### ⭐⭐⭐⭐⭐ A customer made mistake *by A***R on December 16, 2021* The product enabled me to use a 2" eyepiece on a 1.25" telescope. My telescope is 1.25" and I needed this adapter to enable me to accommodate a 2" 2.5X Astromania Barlow lens on my 1.25" telescope. When the items arrived I tried it on the telescope and I couldn't get the Barlow lens to focus no matter what I did. I tried it on terrestrial which usually works quite well but it still didn't focus so I figured the setup I had was incompatible with a 1.25" telescope and sent it back asking for a refund. Now the product itself was fine. I'm sure it works great with a 2" telescope. The construction of the lens/adapter was great. It felt like it was made of metal; however, it was rather heavy as if it was made for a much bigger more expensive telescope. My telescope was neither. Like I said it was my mistake ordering something that I felt might not work with what I had. Would I recommend it to others? Yes. I'm sure it would work great on a larger, better-designed 2" telescope. Also, customer service was great and they issued a prompt refund once they go a notification from Khols (one of their drop-off points) that the items were turned over to them for shipping.
