## Description

Barlow Lens 2X, Bysameyee 1.25 Inch Fully Multi-Coated Metal Barlow Lens with M42 Thread Camera Connect Interface for Telescope Eyepiece

Review: Great quality for the money! - What an easy way to boost your telescope's magnification. This barlow lens has very good (even heavy) build quality and works as advertised. It comes with great lens caps at both ends to keep the dust out (which can be a real problem). Just remember to put it onto your scope first and then add your 33x or 66x (or whatever) optics after that. Fitment is great! And the pricetag is a real bonus!
Review: Good to have. - Objects are clear and beautiful. I use this with my Dianfan 650/150 telescope. When I place it with the 25mm I can barely see the rings of Saturn and the moons around Jupiter. With the 10mm, things get blurry because I think I am going past what my telescope can handle. Calculate whether this makes sense for you and your telescope. If it can work, I recommend it.

## Features

- Doubles the Magnification: This 2X Barlow lens doubles the magnification and capacity of any 1.25 inch eyepiece at the cost of a single eyepiece.
- Interface with M42x0.75 Thread: With T/T2 (M42x0.75mm) male thread for T/T2 connectors, work as a t adapter. Connect DSLR or SLR camera to telescope easily via a separate sale t ring adapter. (Adapter not included)
- Multilayer HD Broadband Green Film Optical Glass Lens: Offer a high quality observation without introducing additional chromatic aberration. Chromatic corrected; provide high transmittance; ensure clear; sharp views.
- Quality Made: Aluminum stock and black anodized body, precision machined; sturdy for a long term use.
- Free Dust Cap: Keeps lens clear easily with 2 pairs of dust cover. With safety undercut and brass compression ring, ensure the eyepiece barrels will not be marred by the captive set screw.
