Things to consider before buying Barlow lenses:
Focal length with usage requirements: The distance from the lens to the focal plane or point where the eyepiece or camera would go. It also means the length of the telescope, the point from where the image is viewed to the point where it is formed. A good focal point is essential in forming a clear image.
Check for chromatic aberration: Confirm if there’s a problem or flaw in optic lenses where there is fringing of colour, that is the lens is unable to focus all the colours on a singular plane.
Learn how to insert a Barlow lens: To insert a Barlow lens with a telescope, you remove the eyepiece from the telescope first. In its place attach the Barlow lens and then insert the eyepiece into the Barlow.

Glossary
Throughout our Barlow lens reviews, we’ve used a few technical terms. Here is what each of them means.
Focal length
It is simply the distance from the lens to the focal plane or point where the eyepiece or camera would go. It also means the length of the telescope, the point from where the image is viewed to the point where it is formed.
Eye-relief
To put it in the most simple manner, it is the distance from the outer lens to the eyepoint or the pupil of the viewer.
Magnification
The amount to which an image can be enlarged. This is a highly desirable optic property. The greater the magnification, the greater the details in the image. Remember magnification does not equal image quality.
Focal length
It is simply the distance from the lens to the focal plane or point where the eyepiece or camera would go. It also means the length of the telescope, the point from where the image is viewed to the point where it is formed.
