Note:
1. The image is for illustration purpose only and the telescope eyepiece is not included in this listing. This Barlow lens has been designed to fit 1.25" eyepieces with 30x1mm barrel thread.

2. Sometimes when a DSLR camera is connected to a telescope with the camera lens being removed, or an image diagonal lens is added to the telescope (to convert the upside down image to right side up), the image cannot be focused on the camera's viewfinder (or seen through the eyepiece). This is often because the image focus point is shifted beyond the focus adjustment range of the telescope. This compact lens also serves the purpose of adjusting the image focal point and enables the camera to get a focused image through a wide range of telescopes.
