Astromania 2X Barlow Lens Upgraded 1.25 inch Metal Fully Multi Coated Telescope Accessory with M42 Thread Camera Connect Interface for Telescope Eyepiece, Telescope Barlow Lens with Filter Thread
ABOUT LATEST 2X BARLOW LENS Give your telescope eyepieces a 2x power boost! The Shorty 1.25-inch 2x Barlow Lens doubles the power of any 1.25-inch telescope eyepiece it is used with. For about the cost of a single eyepiece or less, the practical Shorty 2x Barlow effectively doubles the number of telescope eyepieces at your disposal.
MAIN FEATURES:
• Applies to all 1.25-inch interface telescopes
• Metal barlow magnification 2 times magnification
• Imaging clarity can be up to 15 times
• Apo design and multi-coated lens
• Full metal constructed and precisely CNC-machined
SPECIFICATION: Diameter: 1.25" (31.7mm) Magnification factor: 2X Lens material: Pure optical glass lens Lens coating: Multilayer HD broadband green film Sleeve material: Metal Thread interface: M42X0.75 pitch Color: Black
Optical Components -- The Real Physical Calculation Magnification The Shorty 2x Barlow Lens doubles the magnifying power of any 1.25- inch eyepiece, essentially dividing the eyepiece's focal length by a factor of 2. For example: Using a 25mm eyepiece in the Shorty 2x Barlow provides the same magnification a 12.5mm eyepiece would normally exhibit (25 / 2 = 12.5).
Using this simple formula, you can easily determine how each of your 1.25- inch telescope eyepieces will perform when inserted in the Shorty 2x Barlow Lens. A 20mm ocular will behave like a 10mm eyepiece; a 6mm eyepiece will provide the magnification of a 3mm eyepiece, and so on. Using the Shorty 1.25- inch 2x Barlow Lens is easy. Simply insert the Shorty 2x Barlow into your telescope's focuser or diagonal, and then insert any 1.25- inch eyepiece into the Shorty, gently securing it in place with the two thumbscrews. Then, adjust the telescope's focus wheels to enjoy double the magnification of the eyepiece used. Think of the money you can save with this practical and affordable telescope eyepiece accessory!
Advantages of Latest 2X Barlow Lens
The 2X barlow lens body adopts precision CNC machining, and the internal thread design can eliminate stray light and reflected light, making the captured image clearer.
The housing is precision machined from aluminum stock and black anodized to a hard finish. The lens edges and inner barrel are blackened to provide maximum contrast.
This Barlow features an air-spaced, three-element, Apo design with fully multicoated optics which can effectively reduce reflected light, increase light transmittance, and provide you with brighter and clearer images.
【Updated Detail Design】 The body is all-metal construction with premium aluminum stock and black anodized body by CNC, and optical lense adopts apochromatic glass. Also, it has extra filter thread for mounting any 1.25" telescope filter and improved two large locking thumbscrews can make to fix eyepiece tightly and conveniently.
【2x Magnification Result】 The high-quality barlow lens provide a 2x increase in magnification for allowing you look more closely and more detailed at the moon's surface and other planet during astronomical journey.
【Muti-Coated Optics Lense】 Anti-reflective internal finish to maximize image contrast. The optical glass lens offers better viewing without introducing additional chromatic aberration for obtaining color correction and providing high light transmission, ensuring a clear, sharp view.
【For Visual Observation】 1.25-Inch Telescope Eyepiece Extension Tube provides extra focuser back travel which is often needed for short-range terrestrial viewing or astrophotographic applications. Barlow element separates from extension tube and threads directly into a 1.25" eyepiece, doubling the power of 1.25" telescope eyepiece with this barlow lens - for 1.25" eyepieces from Celestron, Orion, Sky-Watcher, Meade and most brands of telescope.
【Astrophotography Shooting Achievement】 The barlow lens will solve the problem about some T-adapters that some telescopes will not focus properly without barlow to get infinity focus. M42x0.75 male thread allows connection of a SLR/DSLR camera or mirrorless camera with T-ring to telescope, which can works as a T-adapter, connect DSLR/SLR camera to telescope easily via a separate sale T-ring adapter or a camera lens to capture different views of planets and nebulae in the night sky.
