About this deal

The 2x Achromatic Barlow lens doubles the magnification of an eyepiece, without any noticeable loss in image quality. Therefore, an increase in the effective focal length of the telescope results in an increase in magnification. Both Barlow lenses and Powermates act as image amplifiers by increasing the effective focal length of your telescope, thereby increasing the magnification achieved with any eyepiece. It enables you to use eyepieces with a long focal length and therefore comfortable eye relief for higher magnification.

Go behind the scenes with Celestron’s product development team and learn more about our award-winning and patented innovations. The most important factor in ensuring successful microscopic imaging is choosing the appropriate optics and camera for your application that gives you more data and higher image quality. Typical Barlows have a magnification of 2x and are composed of two or sometimes three elements in a single group, forming a negative lens.This award-winning optical system reduces visual defects like field curvature and coma, creating an ultra-flat field for pinpoint stars all the way to the edge of today’s largest imaging sensors. This three-element multicoated design places the lower lens element at the very base of the barrel, meaning it does not include a filter thread. The Tri-Mag 3x Barlow is a simple design neatly finished in a black silk with a plain, mainly chrome, 1. We are using the very latest Zygo MX software to provide a more detailed report compared to other standard reports. A Barlow lens is an optical tube containing lens elements that diverge the light passing through them.

The magnification factor of the VIP Barlow at visual use depends on the distance between the top end of the Barlow element and the eyepiece. With the Barlow element you can move the focal plane further out, eliminating this problem in most cases. There are two retaining thumbscrews to hold the eyepiece in place, but there is no anti-marring compression ring.Also can be used to attach your camera (with appropriate T-Ring) with or without the lens cell for astrophotography. Subsequently, you can use lower power eyepieces in Barlows to act as much more powerful eyepieces, but retain the larger ocular size and more comfortable viewing that comes with lower power eyepiece designs. It has a middling weight of the lenses reviewed at 165g, and the body is elegantly designed, with a silver undercut lens barrel and chunky rubber grip. When you use a Barlow lens with an eyepiece, you get double the magnification, but the eye relief is not affected.
