Telescope Barlow Lens for Telescope Eyepiece

Each telescope has its own maximum magnification capability. After this maximum, the image becomes blurred. The maximum usable magnification is usually twice the telescope's aperture. For instance, a 60mm aperture telescope has a maximum usable magnification of 120x.

The FMC (fully multi-coated) 2-group lenses can increase light transmission and produce a more crisp and sharp image. The internally blackened barrel helps avoid internal reflection and maximize contrast.

The 5x Barlow lens can magnify the image by 5x, allowing you to see the moon's craters with a low-power eyepiece, making observations more comfortable. If you have a 30mm eyepiece paired with a 5x Barlow, you can achieve 6mm of magnification. Simply insert the Shorty 5x Barlow into your telescope's focuser or diagonal, then insert any 1.25-inch eyepiece, securing it with the thumbscrews. Adjust the telescope's focus to enjoy 5 times the magnification of the eyepiece used.

The entire body of this 5x Barlow lens is made of durable aluminum alloy, ensuring long-term use.

If you're unable to focus the telescope, it's likely that the magnification has exceeded the telescope's maximum capability. Similarly, if the image quality is poor, it could be due to the magnification exceeding the telescope's limits or the telescope being out of focus.

It is common for image quality to decrease when using a Barlow lens, as the image is being further enlarged. Consequently, you may observe fewer details when using a Barlow compared to without it, especially when observing flat or less detailed celestial objects.

Compared to other products, the SV198 Guide Scope, Aspheric Eyepiece, Cell Phone Adapter Mount, SV165 Mini Guide Scope, SV207 SPL Eyepiece, and SV105 electronic eyepiece offer different features and specifications, with varying customer ratings and prices.

The 5x Barlow lens doubles the magnification of any 1.25-inch eyepiece, effectively doubling the capacity of an existing set of eyepieces at the cost of a single eyepiece. The lens is made of quality aluminum stock with a black anodized body, featuring a 3-element, 2-group multi-coated optical design for crisp, sharp images. The shorty aluminum stock and black anodized body provide a convenient, long-term solution, with the 2-element, 1-group broadband green film multi-coated optical glass and blackened housing maximizing image contrast.
