ASTRO EYEPIECE 1.25" OD
Are you in need of a good quality eyepiece / Barlow? Do you want to upgrade the magnifying power of your telescope? We offer fine standard eyepieces and Barlow lens for your telescope. Our reasonable parfocalised eyepieces are manufactured with a 1.25"OD American Standard barrel diameter.


SUPER PLOSSL EYEPIECE
These four element oculars feature the classic symmetrical doublet design which is very famous for field correction (Image view is very sharp from the centre to the edge). Multi-coated and black coloured edges of lenses deliver a crisp, high contrast image (specially priced for Planetary viewing). It’s field of view is 52° panorama for F/ratios as low as F/4.5. (44° for the 40mm Supper Plossl). These eyepieces are excellent performers with telescopes of all types. It also has a thread for photo-visual filters.

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.

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.

    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.
