3x Achromatic Barlow lens, 3x magnification, 1.25″ fitting

Description

This 3x achromatic Barlow lens can be fitted to a standard 1.25″ eyepiece holder of telescopes to increase the overall image magnification by 3 times.

Description:

• Increase the overall image magnification by 3 times.
• Can fit almost all types of telescopes with a standard eyepiece barrel diameter of 1.25″ (31.75mm).
• Built with top quality optical glass Bak4 and with multiple anti-reflection achromatic green coatings.
• Double lenses for high quality images without false colour.
• Overall length: 66mm
• Eyepiece holder length within the Barlow lens: 30mm
• Length of Barlow lens section to fit into the scope’s eyepiece barrel: 29mm

Note: A Barlow lens multiplies the focal length of your telescope, increasing magnification without needing additional eyepieces.
For example: A 25mm eyepiece becomes equivalent to ~8.3mm; A 10mm eyepiece becomes ~3.3mm

This allows you to achieve high-power viewing—especially useful for observing:

• The Moon’s craters

• Jupiter and its cloud bands

• Saturn’s rings

• Venus phases

• Double stars

• Fine details on terrestrial targets
