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

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
Laser Colliminator . . . . Rs. 4,800

Columniation, or optical alignment, is critical for the performance of all aspheric systems. Our laser colliminator incorporates a viewing port that allows you to see the reflected beam. Simply insert the device into your 1.25"OD focuser, and adjust the optics until the return spot superimposes on the beam. Check for both high and low focuser position. The laser colliminator is ideal for any reflector, especially those with focal ratios of f/5 or lower. It fits any 1.25" eyepiece holder and Includes two LR-44 batteries and instructions. Length, 5-3/4". Precise collimation ensures that you’ll enjoy the sharpest possible images
GREEN Laser Pointer . . . . Rs. 7,500

523 nm / 5mW
After a telescope, the best aiming tool at night powered by AAA battery is a GREEN Laser Pointer. It can seemingly touch the stars millions of miles away. Ideal pointing tools for Astronomy compared with red laser pointer, the bright green beam remains visible and penetrates the air much further. On a clear night it can easily shine a dot miles away. With it sharp laser beam, you can pinpoint the exact star and constellation you want. Greatly accelerates mapping, learning astronomy and professional presentation
