The Benefits Of Barlow Lens
   
One of the most useful and cost effective tools in an amateur astronomer accessory case is a good quality Barlow lens. It is a simple concave (negative) lens or doublet that increases the instrument's effective focal length boosting the magnifying power of any eyepieces. Using a 2x Barlow your 12mm eyepiece effectively becomes a 6mm eyepiece. Also increases eye relief. Here STARTRACKER SYSTEM offers four variety of Barlow lenses

For those observing targets where you need more power than your eyepieces alone can provide, we offer the new ED Barlow lens to offer 3x magnification boost to any 1.25" eyepiece it's used with.

This is desirable for lunar and planetary observing and for extracting higher powers from fast telescopes such as f/5 and f/4 refractors and reflectors.The features 3x ED Barlow lens use two-elements, fully multi-coated lenses with blackened edges for excellent color correction and sharpness that effectively triples the focal length of the telescope's optics. 

All housing is precision machined from aluminum and black anodized to a hard finish. The chrome portion of the barrel are glare threaded and blackened inside to provide maximum contrast. The lens end of the barrel is threaded to accept any standard 1.25" filters.

The GSO Universal 1.25" T-Adaptor Barlow is designed to allow you to attach your Digital SLR Camera to any telescope with a standard 1.25" focuser and simply drops in like an eyepiece. This versatile Barlow will double the power of any 1.25" eyepiece and triple with extension adapter for visual use. The adaptor requires the appropriate T-Ring for your make of camera to securely attach the camera to your telescope's focuser. The telescope then becomes the camera lens allowing you to image the night sky. The built in Barlow lens in this T adaptor will increase the magnification by 2x or 3x, ideal or Lunar and Planetary imaging. 

Doubles and triples the magnification of eyepieces & has a T thread for camera and Brass compression ring.

This Barlow T-Adapter will also solve the issue on many Newtonian reflectors that do not reach focus with a Digital SLR.
Features T-Thread for direct camera attachment

Enjoy your telescope more with our colour-corrected 2 element Barlow. This 1.25” OD 2x or 3x Barlow is for high power application. A Barlow lens is always superior to use in conjunction with a short focal length eyepiece. This is because the Barlow decreases the spherical aberration of the eyepiece being used while retaining it’s superior eye relief, multi-coated for maximum light transmission
 
 
GSO 2x ED-Barlow-Lens (Multicoated) . . . . Rs.4,800. 
   

This 2", 2x Barlow lens is made of high quality materials, including Extra Low Dispersion (ED), fully multi-coated optical lens to translate to higher contrast, sharper images. The lenses have a diameter of 37mm, thus you can even use 2" wide angle eyepieces without vignetting effect.

Our 2" ED Barlow lens comes with a 1.25" adapter, brass compression rings on both the barlow and the 1.25” adapter and barrel is threaded to accept 48mm filters. Two dust cap included.
